Cold quarantine storage is the practice of subjecting citrus fruit to low temperatures after harvesting to comply with stringent international phytosanitary standards for export, but fruit quality can be affected during storage. Therefore, this study investigated the effects of glycine betaine (GB) and/or methyl salicylate (MeSA) on physicochemical changes, chemical attributes of juice, and peel color of 'Moro' blood orange at cold quarantine storage (2 °C) for 60 days. Fruit were treated with GB (15 and 30 mM) by vacuum infiltration at 30 kPa for 8 min and vapor treatment of MeSA (100 µM) for 18 h as well as the combination of both GB concentrations with MeSA. The key findings of this research revealed that the combined treatment of 30 mM GB and 100 µM MeSA significantly mitigated weight and firmness losses in 'Moro' blood orange fruit during the cold quarantine period. Furthermore, there was a decrease in titratable acidity (TA) across all treatments, with the highest TA recorded for the 30 mM GB + 100 µM MeSA combination. Conversely, total soluble solids (TSS), TSS/TA ratio, and juice pH increased in all treatments, with the control treatment displaying the highest values. Regarding peel color parameters, which encompass L* (lightness), b*, hue angle (h°), chroma (C*), and a*, as well as the citrus color index (CCI), these exhibited characteristic changes during cold quarantine storage. However, the application of GB and MeSA, especially at the 30 mM GB + 100 µM MeSA level, noticeably delayed these peel color variations. Overall, GB and MeSA treatments offer significant advantages in preserving the physicochemical characteristics and chemical attributes of 'Moro' blood oranges during cold quarantine storage. These findings underscore the potential of GB and MeSA treatments for maintaining the quality of 'Moro' blood oranges during cold quarantine storage, with a noteworthy synergistic effect between MeSA and GB in preserving fruit quality.

FRUIT quality , *CITRUS fruit growing , *ROOTSTOCKS , *PHOTOSYNTHETIC rates - Abstract
Citrus rootstocks are a relevant tree part that contributes to crops adapting to biotic and abiotic conditions, it becoming a key factor to face the current era of climate change. Although the emphasis of most studies on rootstocks has been placed on the yield and optimization of the citrus fruit grown in different environments, other studies have paid attention to the effect of rootstock on fruit quality. Hence, the quality of citrus fruit is becoming increasingly more relevant as consumers demand high internal and external qualities to eat citrus fruit fresh. To better understand how rootstock influences citrus fruit quality, the literature that focuses on physico-chemical parameters, nutritional compounds and physiological disorders has been revised. This review points out the influence that the external aspects surrounding plants has on fruit quality, such as the rootstock/scion interaction, the water uptake capacity of roots, the modification of the photosynthetic rate or availability of nutrient minerals.

An experiment was conducted to assess the influence of coconut oil and beeswax coating and modified atmospheric packaging (MAP) on postharvest storage quality of lemon at ambient storage. Sorted lemons were washed with water; fruit surface water was removed by using fan and then coated with coconut oil and beeswax mixture (90:10 or 80:20) or only coconut oil. After coating, lemons were kept open in crates or in MAP and stored at ambient condition (21 ± 2 °C and 50 ± 5% RH). The effectiveness of edible coating and MAP in extending the shelf life of lemon with quality was evaluated by determining weight loss, respiration rate, ethylene production rate, firmness, shrinkage, yellowing, decay incidence, total soluble solid (TSS), pH, ascorbic acid, juice content and also organoleptic quality were assessed periodically during storage. The results revealed that coconut oil only and mixtures with beeswax (both formulations) coating especially with MAP had immense effect on retaining green colour, reducing respiration, ethylene production, weight loss and shriveling, preserving firmness and moisture content of lemon throughout the storage.

Colombia requires blackberry genotypes with remarkable traits that improve the competitiveness of this product in the country. The objective of this work was to evaluate the characteristics of the quality attributes in fruits of ten Colombian blackberry genotypes in order to assess their potential in the berry markets but also as a genetic source to be included in breeding programs. The weight of fruits, the equatorial and longitudinal diameters, volume, firmness, color, juice content, flesh content, seed/fruit weight percentage, soluble solids content, acidity, pH and maturity index were evaluated in fruits collected during three different harvest periods in the province of Cundinamarca. Thirty fruits for every genotype and period were harvested and analyzed. These 10 evaluated genotypes showed important differences that allowed separating them into five different groups; however, genotypes 8, 4 and 6 showed the best results regarding size, color, juice content, total soluble solids content, maturity index, firmness and low acidity. These features make them good candidates for incorporating them into breeding programs. Nonetheless, their soluble solids content was considerably lower than values reported for genotypes Prime Ark, Natchez, Ouachita, and Osage that are recognized for these remarkable traits.

Em regiões como o Noroeste do Rio Grande do Sul, destaca-se como uma nova alternativa de renda para vários agricultores. Neste contexto, o presente trabalho teve como objetivo analisar o potencial fitoquímico de alguns cultivares de melão da região Noroeste do Rio Grande do Sul. A análise fitoquímica utilizando como farmacógeno as folhas, foi realizada para a verificação da presença de metabólitos secundários, tais como: saponinas, cumarinas, cardiotônicos, cianogenéticos, alcalóides, taninos, antraquinonas, flavonoides, e óleos voláteis. Também foi avaliado o teor de suco a partir dos frutos. Dentre os cinco cultivares analisados, Gaúcho, Imperial, Hy Mark, Magelan, e Cantaloupe, o cultivar Gaucho apresentou a maior variedade em metabólitos secundários. Na avaliação do teor de suco a cultivar Magelan se destacou em comparação às demais cultivares testadas.The melon (Cucumis melo L.) is a fruit highly appreciated for its qualities and its production has been growing and gaining space in the national and in the international market. In regions like the northwest of Rio Grande do Sul - Brazil, it stands out as a new income alternative for farmers. In this context, this study aimed to analyze the phytochemical potential of some melon cultivars in the northwest region of Rio Grande do Sul. The phytochemical analysis, using the leaves as pharmacogen, was performed to verify the presence of secondary metabolites such as saponins, coumarins, cardiac glycosides, cyanogenetic glicosides, alkaloids, tannins, anthraquinones, flavonoids and volatile oils. The juice content from the fruits was also evaluated. Among the five analyzed cultivars, Gaucho, Imperial, Hy Mark, Magelan and Cantaloupe, cultivar Gaucho had the greatest variety of secondary metabolites. In the assessment of the juice content, cultivar Magelan was superior compared to the remaining tested cultivars.

In this study, X-ray computed tomography (CT) was used as a non-destructive technique to characterise and quantify the internal structure of pomegranate fruit (cv. Wonderful). A commercial X-ray system with a radiation source of 245 kW and electron current of 300 μA was used to generate two-dimensional (2D) radioscopic images which were reconstructed into three dimensional (3D) images for the quantification and volume estimation of internal structural components of fruit. Segmentation of the internal fruit components (arils, peel, kernel, juice content, air space) and single arils was achieved using StudioMax volume graphics software. The calculated volume of each fruit fraction were 162.5 ± 16.2, 163.9 ± 21.4, 16.4 ± 1.8, 10.9 ± 2.6 mL for arils, peel, kernel and air space, respectively which accounted for 48.1, 48.3, 4.9 and 4.1% of total fruit volume. Furthermore, the calculated volume of juice content was 146.1 ± 16.3 mL per fruit which was equivalent to an average of 89.8% of total aril weight, while a single aril (0.3 ± 0.04 mL) accounted for only 0.09% of whole fruit volume. Destructive validation measurements of each fruit fraction showed similar results to non-destructive data, with volumes of 163.3 ± 15.2, 161.8 ± 20.6, 15.1 ± 1.6, and 12.3 ± 4.4 mL for arils, peel, kernel, air space, respectively, while volumes of juice and single aril were 142.7 ± 16.4 and 0.3 ± 0.09 mL per fruit, respectively. Furthermore, the results showed that fruit physical attributes such as length, diameter and peel thickness were underestimated by an average of 0.14%, 1.13% and 5.27%, respectively, while fruit radius was overestimated by 1.75%. Nevertheless, no significant differences were observed for length, diameter, radius and peel thickness between X-ray CT predicted values and actual measurements. This work has demonstrated the capability of X-ray CT as a non-destructive technique to suitably estimate the fruit volume and its fractions which could be employed for fruit quality systems.

Ta, [EN] Citriculture faces changing environmental scenarios that cause biotic and abiotic stress. The rootstock onto which a specific variety is grafted is an important tool to help to improve its agronomic adaptability to each crop area. The present Thesis was carried out to study the effect of rootstock on physico-chemical and nutritional fruit quality in some varieties of commercial interest today: 'Clemenules' and 'Tango' mandarins, and 'Tarocco Rosso' and 'Moro' blood oranges. In 'Clemenules', the fruit of the trees grafted into eight rootstocks at three harvest times was evaluated by performing studies during two seasons. Forner-Alcaide 13 and C-35 Citrange stood out for their earlier color change, which is very interesting for this variety, in which early harvesting is a relevant aspect from the commercial point of view. Forner-Alcaide V17 stood out for maintaining optimum acidity levels until the season ended and presented the highest contents in vitamin C, flavonoids, glucose and fructose. Carrizo Citrange brought about high concentrations of sucrose and vitamin C in fruit. 'Tango' is a mandarin variety that has been recently introduced into the Mediterranean Region. Its harvest time is very interesting because it starts when that of clementines ends. The present Thesis studies changes in the physico-chemical, nutritional and sensorial quality of 'Tango' fruit grafted onto two rootstocks (Carrizo Citrange and Forner-Alcaide 5) during the harvest period in the two main production areas in Andalusia. The results revealed that fruit quality during harvest was influenced by the location, which was particularly related to soil texture composition. In both areas, Forner-Alcaide 5 was the rootstock that induced higher acidity content, and more total soluble solids, sucrose, vitamin C and citric acid in fruit. The physico-chemical determinations, along with the sensorial evaluation, allowed the optimum harvest time to be established depending on the different studied

En esta Tesis se abordó el estudio de los cambios en la calidad fisicoquímica, nutricional y sensorial de la mandarina 'Tango' injertada sobre dos patrones (Carrizo Citrange y Forner-Alcaide 5) en las dos áreas principales de producción de Andalucía. Los resultados revelaron que la calidad de la fruta se vio influenciada por la localización de las parcelas, lo que se relacionó con la composición de la textura del suelo. En ambas localizaciones, Forner-Alcaide 5 indujo mayor contenido en acidez, sólidos solubles totales, sacarosa, vitamina C y ácido cítrico en la fruta. Las determinaciones físico-químicas, junto con la evaluación sensorial permitieron establecer el momento óptimo de recolección dependiendo de las diferentes condiciones estudiadas. También se ha incluido un estudio del comportamiento postcosecha de esta variedad, ya que no existían datos en nuestras condiciones de cultivo. La mandarina 'Tango' presentó síntomas externos de daños por frío a partir de los 20 días almacenada a 1°C y 5°C. Se realizó un estudio micro-estructural para caracterizar la alteración. Los frutos del patrón Forner-Alcaide 5 presentaron una menor incidencia de los daños por frío. El almacenamiento a 9°C no comprometió la calidad externa o interna. Dentro del grupo de naranjas, en los últimos años existe una creciente demanda por las naranjas sanguinas para su consumo en fresco. Para evaluar el efecto del patrón se tomaron las variedades 'Moro' y 'Tarocco Rosso' injertadas sobre ocho patrones. La calidad interna se vio afectada por el momento de cosecha, siendo más evidente en 'Moro'. En ambas variedades el patrón afectó a los parámetros de calidad durante la maduración. En 'Moro', se observó una reducción en el color del zumo debido a la degradación de los antocianos, siendo los patrones C-35, Macrophylla y Volkameriana los que mostraron un mayor descenso. Esta degradación se relacionó con los cambio de la temperatura durante el periodo de recolección. En 'Tarocco Rosso' no se evidenció ninguna degradación, lo que sugiere que esta variedad es menos sensible a los cambios de temperatura. En esta variedad Forner-Alcaide 5 y Forner-Alcaide 13 produjeron fruta con mayor contenido en antocianos y azúcares. Además se llevó a cabo el estudio de la aptitud a la frigoconservación de las variedades de sanguinas 'Tarocco Rosso' y 'Sanguinelli'. Mientras que la calidad interna no se vio afectada por el almacenamiento (1°C, 5°C y 9°C) durante 45 días, la fruta presentó síntomas de daños por frío a 1°C. 'Sanguinelli' presentó mayor incidencia que 'Tarocco Rosso'.

La mandarina 'Tango' va presentar símptomes externs de danys per fred a partir dels 20 dies emmagatzemada a 1°C i 5°C. Es va realitzar un estudi micro-estructural per a caracteritzar l'alteració provocada per les baixes temperatures. Els fruits del patró Forner-Alcaide 5 van presentar una menor incidència dels danys per fred. L'emmagatzematge a 9°C no va comprometre la qualitat externa o interna d'aquesta varietat. Dins del grup de taronges, en els últims anys existeix una creixent demanda per les taronges sanguines pel seu consum en fresc. Per a avaluar l'efecte del patró sobre sanguines es van prendre dues varietats, 'Moro' i 'Tarocco Rosso' empeltades sobre huit patrons. La qualitat interna es va veure influenciada pel moment de collita, la qual cosa va ser més evident en la varietat 'Moro'. En totes dues varietats el patró va afectar els canvis en els paràmetres de qualitat estudiats. En 'Moro', es va observar una reducció en el color del suc degut a la degradació del antocians. Aquesta degradació es va relacionar amb el canvi de la temperatura experimentada durant el període de recol·lecció. 'Tarocco Rosso' és menys sensible als canvis de temperatura. En aquesta varietat els patrons Forner-Alcaide 5 i Forner-Alcaide 13 van produir la fruita amb major contingut en antocianos i sucres. A mes s'aporta l'estudi de l'aptitud a la frigoconservació en les sanguines 'Tarocco Rosso' i 'Sanguinelli'. Mentre que la qualitat interna no es va veure afectada per l'emmagatzematge a cap de les temperatures assajades (1°C, 5°C i 9°C) durant 45 dies, la fruita va presentar símptomes de danys per fred a 1°C. `Sanguinelli' va presentar major incidència que 'Tarocco Rosso'. La fruita es pot emmagatzemar entre 5°C i 9°C durant 30 dies en el cas de 'Sanguinelli' i fins a 45 en e, [EN] Citriculture faces changing environmental scenarios that cause biotic and abiotic stress. The rootstock onto which a specific variety is grafted is an important tool to help to improve its agronomic adaptability to each crop area. The present Thesis was carried out to study the effect of rootstock on physico-chemical and nutritional fruit quality in some varieties of commercial interest today: 'Clemenules' and 'Tango' mandarins, and 'Tarocco Rosso' and 'Moro' blood oranges. In 'Clemenules', the fruit of the trees grafted into eight rootstocks at three harvest times was evaluated by performing studies during two seasons. Forner-Alcaide 13 and C-35 Citrange stood out for their earlier color change, which is very interesting for this variety, in which early harvesting is a relevant aspect from the commercial point of view. Forner-Alcaide V17 stood out for maintaining optimum acidity levels until the season ended and presented the highest contents in vitamin C, flavonoids, glucose and fructose. Carrizo Citrange brought about high concentrations of sucrose and vitamin C in fruit. 'Tango' is a mandarin variety that has been recently introduced into the Mediterranean Region. Its harvest time is very interesting because it starts when that of clementines ends. The present Thesis studies changes in the physico-chemical, nutritional and sensorial quality of 'Tango' fruit grafted onto two rootstocks (Carrizo Citrange and Forner-Alcaide 5) during the harvest period in the two main production areas in Andalusia. The results revealed that fruit quality during harvest was influenced by the location, which was particularly related to soil texture composition. In both areas, Forner-Alcaide 5 was the rootstock that induced higher acidity content, and more total soluble solids, sucrose, vitamin C and citric acid in fruit. The physico-chemical determinations, along with the sensorial evaluation, allowed the optimum harvest time to be established depending on the different studied conditions. This Thesis also includes a study about this variety's postharvest behavior as no data are available for our crop conditions. The 'Tango' mandarin presented outer chilling injury symptoms after being stored for 20 days at 1°C and 5°C. A microstructural study was done to characterize the alteration caused by low temperatures. The Forner-Alcaide 5 rootstock fruit showed a lower chilling injury incidence. Storage at 9°C did not compromise quality fruit. Among oranges, demand for blood oranges to be eaten fresh has grown in recent years, basically due to their high content in anthocyanins and their positive effect for human health. To assess the effect that rootstock had on blood oranges, two varieties were taken, 'Moro' and 'Tarocco Rosso', grafted onto eight rootstocks. Internal quality was strongly influenced by harvest time, which was more evident for 'Moro'. In both varieties, rootstock affected changes in the quality parameter studied. In 'Moro', juice color faded as anthocyanins degraded, and rootstocks C-35 Citrange, Macrophylla and Volkameriana showed the most marked reduction. Such anthocyanin degradation was related to the change in temperature that took place during the harvest period. In 'Tarocco Rosso', anthocyanins did not undergo degradation, which suggests that this variety is less sensitive to changes in temperature. In this variety, rootstocks Forner-Alcaide 5 and Forner-Alcaide 13 gave fruit with a higher content of anthocyanins and sugars. This Thesis also includes a study of the suitability of cold storage of two blood orange varieties: 'Tarocco Rosso' and 'Sanguinelli'. Although storage at any tested temperature (1°C, 5°C and 9°C) did not affect internal quality for 45 days, fruit displayed chilling injury symptoms at 1°C, with a higher incidence for 'Sanguinelli' than for 'Tarocco Rosso'. Fruit can be stored between 5°C and 9°C for 30 days for 'Sanguinelli' and for up to 45 days with 'Tarocco Rosso'., This study has been supported by Instituto Valenciano de Investigaciones Agrarias and co-financed by FEDER and European Social Fund.

Citrus rootstocks are a relevant tree part that contributes to crops adapting to biotic and abiotic conditions, it becoming a key factor to face the current era of climate change. Although the emphasis of most studies on rootstocks has been placed on the yield and optimization of the citrus fruit grown in different environments, other studies have paid attention to the effect of rootstock on fruit quality. Hence, the quality of citrus fruit is becoming increasingly more relevant as consumers demand high internal and external qualities to eat citrus fruit fresh. To better understand how rootstock influences citrus fruit quality, the literature that focuses on physico-chemical parameters, nutritional compounds and physiological disorders has been revised. This review points out the influence that the external aspects surrounding plants has on fruit quality, such as the rootstock/scion interaction, the water uptake capacity of roots, the modification of the photosynthetic rate or availability of nutrient minerals.

Colombia requires blackberry genotypes with remarkable traits that improve the competitiveness of this product in the country. The objective of this work was to evaluate the characteristics of the quality attributes in fruits of ten Colombian blackberry genotypes in order to assess their potential in the berry markets but also as a genetic source to be included in breeding programs. The weight of fruits, the equatorial and longitudinal diameters, volume, firmness, color, juice content, flesh content, seed/ fruit weight percentage, soluble solids content, acidity, pH and maturity index were evaluated in fruits collected during three different harvest periods in the province of Cundinamarca. Thirty fruits for every genotype and period were harvested and analyzed. These 10 evaluated genotypes showed important differences that allowed separating them into five different groups; however, genotypes 8, 4 and 6 showed the best results regarding size, color, juice content, total soluble solids content, maturity index, firmness and low acidity. These features make them good candidates for incorporating them into breeding programs. Nonetheless, their soluble solids content was considerably lower than values reported for genotypes Prime Ark, Natchez, Ouachita, and Osage that are recognized for these remarkable traits. RESUMEN Colombia requiere identificar materiales de mora con características sobresalientes que permitan impulsar el crecimiento de esta cadena de producción en el país. Por esta razón el objetivo de ese trabajo fue evaluar los atributos de calidad de fruta de 10 genotipos de mora para determinar su potencial en los mercados de bayas, y como fuente genética para incluirlos en los programas de mejoramiento. El peso, diámetro ecuatorial y longitudinal volumen, firmeza, color, contenido de jugo, contenido de pulpa y porcentaje de peso de semilla/peso de fruta, contenido de sólidos solubles, acidez, pH y el índice de madurez fueron evaluados en frutas recolectadas en tres períodos de cosecha diferentes, en el departamento de Cundinamarca. Se evaluaron y analizaron 30 frutos por genotipo y periodo. Los 10 genotipos mostraron diferencias importantes que permitieron separarlos en cinco grupos diferentes; sin embargo, los genotipos 8, 4 y 6 mostraron los mejores resultados en cuanto a tamaño, color, contenido de jugo, contenido total de sólidos solubles, índice de madurez, firmeza y baja acidez. Estas características los hacen buenos candidatos para ser incorporados en los programas de propagación. Finalmente, el contenido de sólidos solubles fue considerablemente más bajo que los valores reportados para los genotipos Prime Ark, Natchez, Ouachita y Osage, los cuales son reconocidos por estas características sobresalientes.

Grapefruit growers in the tropics require information about existing and new citrus cultivars with high productivity potential. The objective of this study was to determine the growth, yield, and fruit quality performance of seven pigmented and four white grapefruit cultivars under the dry tropic conditions of Colima, Mexico. The trees were budded on sour orange ( Citrus aurantium L.) rootstock and planted at a distance of 8 × 4 m. ‘Oroblanco’ and ‘Marsh Gardner’ white-fleshed grapefruit cultivars and ‘Chandler’, a pink-fleshed pummelo, were the largest trees with the greatest height (5.0–5.6 m), canopy diameter (6.2–6.3 m), trunk diameter (21.9–23.3 cm), and canopy volume (109–123 m3). Lower height (4.3–4.8 m) and canopy volume (73–96 m3), but with similar canopy diameter to the previously mentioned cultivars, were recorded for the remaining pigmented cultivars. ‘Chandler’ pummelo and four pigmented grapefruit cultivars (‘Shambar’, ‘Río Red’, ‘Ray Ruby’, and ‘Redblush #3’) had yearly productions of 34.8, 34.9, 34.1, 32.7, and 30.6 ton ha−1, respectively. The most productive white grapefruit cultivar was ‘Marsh Gardner’ (30.5 ton ha−1). Grapefruit cultivars having the largest fruit size showed a higher inverse relationship between fruit weight and yield than those with small fruit. Most genotypes had higher values of fruit weight, juice content, and maturity index than those required by the local market. The most promising grapefruit cultivars based on their acceptable growth, yield superior to 30 ton ha−1, and acceptable fruit color were ‘Río Red’, ‘Shambar’, ‘Ray Ruby’, and ‘Redblush #3’.

The objective of this work was to evaluate the effect of nine rootstocks on 'Jaffa' sweet orange (Citrus sinensis) for its vegetative, productive, and qualitative traits, and for its susceptibility to three pest mites (Eutetranychus banksi, Tetranychus mexicanus and Phyllocoptruta oleivora). The following parameters were evaluated: vegetative growth, yield, physiochemical characteristics of fruit, and density of pest mites. 'Sunki Tropical' mandarin conferred high cumulative yields whereas 'Orlando' tangelo and 'Rugoso Vermelho' lemon imparted bigger fruit with low brix, and less acidity to 'Jaffa'. Indio and 'Riverside' citrandarins induced more acid fruit of smaller sizes, as well as low-cumulated yields and canopy volumes. Also, the 'Cravo Santa Cruz' lime, 'San Diego' citrandarin, and the hybrids HTR-051 and LVK x LCR-010 conferred lower-cumulated yields to 'Jaffa'. The rootstocks did not influence the population levels of the evaluated mites. 'Sunki Tropical' mandarin, 'Cravo Santa Cruz' lime and 'Rugoso Vermelho' lemon stand up as excellent rootstock options for 'Jaffa' sweet orange in the Northeastern Brazil.

[Display omitted] • The quality of the Persian lime fruit was evaluated under tropical conditions. • The rootstock's environmental interaction is crucial in the quality of Persian lime. • Swingle citrumelo showed the highest TSS and TA. • Interaction location * rootstock determines color parameters. • The more precipitation, the higher the juice content. International commerce of Persian limes (Citrus latifolia Tanaka) has grown in recent years. Peel color is the most important quality parameter together with juice content and a good balance between TA and TSS. The rootstock's performance determines the characteristics of the fruit in the environmental conditions where it is established. Consequently, to meet the requirements of the Persian lime fruit market, it is important to know the effects of the rootstock, environmental conditions, and its role in the quality of the fruit. To achieve this aim, Persian lime was grafted onto six rootstocks established in three locations with different environmental conditions and fruit quality parameters were evaluated. Results show that the environmental conditions strongly affect the quantity of juice content, as well as TA and TSS, whereas rootstocks influence TSS, and TA. The rootstock's interaction with environmental conditions determined the firmness, and all color parameters evaluated. The study concluded that Persian limes produced under the conditions evaluated led to better fruit quality, fulfilling all the market requirements and desirable traits such as high TSS and TA content and greener fruits.

Yield and quality of yellow and sweet passion fruits produced in northern state of São Paulo, Brazil were evaluated, including FB200 Yellow Master, Isla Redondo Amarelo, BRS Rubi do Cerrado, BRS Sol do Cerrado and BRS Gigante Amerelo cultivars, GP09-02, GP09-03, H09- 09, H09-14, HFOP-08 and HFOP-09 intraspecific hybrids, and two selections of sweet passion fruits, BGP DG and BGP DP. Experimental design was comprised of randomized blocks with 13 treatments, five replicates and three plants per plot. BGP DG was the sweet passion fruit selected for fresh fruit market as a result of its higher yield (52.7 t ha-1) and fruit size and mass (243 g). Among yellow passion fruits, GP09-02 stood out because it showed the highest number of fruits per plant after two years of cultivation, even though GP09-02, H09-09, BRS Sol do Cerrado, Isla Redondo Amarelo and FB200 had also presented higher juice content, on average 32.3%, and equivalent accumulated fruit yield. All fruits had high soluble solids contents, with higher concentration for sweet passion fruits (20.0 °Brix) than yellow passion fruits (average of 14.28 °Brix). These cultivars, hybrids and selections have potential for cultivation in northern state of São Paulo and in regions with similar edaphoclimatic conditions. Resumo Avaliaram-se produção e qualidade de frutos de maracujazeiros-amarelos e doces na região norte do Estado de São Paulo, incluindo-se as cultivares FB200 Yellow Master, Isla Redondo Amarelo, BRS Rubi do Cerrado, BRS Sol do Cerrado e BRS Gigante Amarelo, os hibridos intraespecíficos de maracujazeiro-amarelo GP09-02, GP09-03, H09-09, H09-14, HFOP- 08 e HFOP-09, e duas seleções de maracujazeiro-doce, BGP DG e BGP DP. O delineamento experimental foi em blocos casualizados, com 13 tratamentos, cinco repetições e três plantas na parcela. O maracujazeiro-doce BGP DG foi selecionado para mercado de frutas frescas, em função da elevada produtividade (52,7 t ha-1) e da maior massa e tamanho de fruto (243 g). Entre os maracujazeiros-amarelos, o híbrido GP09-02 destacou-se pelo maior número acumulado de frutos por planta, em dois anos de cultivo, embora GP09-02, H09-09, BRS Sol do Cerrado, Isla Redondo Amarelo e FB200 tenham apresentado maior rendimento de suco, em média 32,3%, e produtividade acumulada por área semelhante. Todos os frutos apresentaram elevada concentração de sólidos solúveis, maior nos maracujás-doces (20,0 °Brix) em relação aos amarelos (média de 14,28 °Brix). Essas cultivares, híbridos e seleções apresentam potencial de cultivo no norte do Estado de São Paulo e em regiões com condições edafoclimáticas similares.

[SPA] El objetivo de la investigación fue evaluar los efectos a largo plazo del riego con agua regenerada (AR) y agua del trasvase (AT) y diferentes estrategias de riego (control, C, y riego deficitario controlado, RDC) sobre la calidad de pomelos durante su almacenamiento en frío. Los resultados mostraron que el riego con AR y, principalmente, el RDC incrementaron la cantidad de solidos solubles, mejorando así el índice de madurez. Sin embargo, el AR combinada con RDC disminuyó el nº de frutos de la categoría de mayor tamaño al final del almacenaje y AT-RDC presentó el menor contenido en zumo. [ENG] The aim of our research was to discover the effects of the long-term irrigation with saline reclaimed (RW) and transfer (TW) water and different irrigation strategies: control (C) and regulated deficit irrigation (RDI) on fruit quality of grapefruit during cold storage. Result showed sugar/acid ratio was mainly increased by RDI, but also by RW, due to an important increase in soluble solid content. However, RDI combined with RW, significantly decreased the number of fruits in the largest category 5 at the end of cold storage and TW-RDI showed lower values of juice content.

O melão (Cucumis melo L.) é uma fruta muito apreciada por suas qualidades e sua produção vem crescendo e ganhando espaço no mercado nacional e internacional. Em regiões como o Noroeste do Rio Grande do Sul, destaca-se como uma nova alternativa de renda para vários agricultores. Neste contexto, o presente trabalho teve como objetivo analisar o potencial fitoquímico de alguns cultivares de melão da região Noroeste do Rio Grande do Sul. A análise fitoquímica utilizando como farmacógeno as folhas, foi realizada para a verificação da presença de metabólitos secundários, tais como: saponinas, cumarinas, cardiotônicos, cianogenéticos, alcalóides, taninos, antraquinonas, flavonoides, e óleos voláteis. Também foi avaliado o teor de suco a partir dos frutos. Dentre os cinco cultivares analisados, Gaúcho, Imperial, Hy Mark, Magelan, e Cantaloupe, o cultivar Gaucho apresentou a maior variedade em metabólitos secundários. Na avaliação do teor de suco a cultivar Magelan se destacou em comparação às demais cultivares testadas. The melon (Cucumis melo L.) is a fruit highly appreciated for its qualities and its production has been growing and gaining space in the national and in the international market. In regions like the northwest of Rio Grande do Sul - Brazil, it stands out as a new income alternative for farmers. In this context, this study aimed to analyze the phytochemical potential of some melon cultivars in the northwest region of Rio Grande do Sul. The phytochemical analysis, using the leaves as pharmacogen, was performed to verify the presence of secondary metabolites such as saponins, coumarins, cardiac glycosides, cyanogenetic glicosides, alkaloids, tannins, anthraquinones, flavonoids and volatile oils. The juice content from the fruits was also evaluated. Among the five analyzed cultivars, Gaucho, Imperial, Hy Mark, Magelan and Cantaloupe, cultivar Gaucho had the greatest variety of secondary metabolites. In the assessment of the juice content, cultivar Magelan was superior compared to the remaining tested cultivars.
