Sweet sorghum Sorghum bicolor (L.) Moench) is a promising crop for bioethanol production characterized by its high biomass yield, sugar-rich stalks, facile juice extraction, and ability to adapt to different production systems. The objective of this study was to assess the effects of cultivation practices (soil treatments) on the juice, sugar, and ethanol yields of sweet sorghum variety Roger. Three methods of tillage (minimum, traditional, and traditional tillage with rupture of the plow layer) and three types of fertilizers (inorganic, organic, and without fertilizer) were assayed. The best results of stem yield (44.3 tons/ha), juice production (25.6 m3/ha), concentration of soluble solids in the juice (16.9 °Brix), and juice ethanol yield (2.1 m3/ha) were obtained under a mixture of traditional plowing with plow layer breaking, applying an organic fertilizer. In addition, the extracted juice allowed yeast (industrial Saccharomyces cerevisiae PE-2) growth and conversion to ethanol without the need for nutrients supplementation. Therefore, sweet sorghum continues to be an interesting bioenergetic crop for production of first-generation biofuels. [ABSTRACT FROM AUTHOR]

PEST control ,ARID regions ,CORN ,DROUGHT tolerance - Abstract
Objective: To analyze the race diversity and geographic distribution of the native maize landraces currently cropped at southern Nuevo León, México. Design/Methodology/Approach: Data was obtained from 41 accessions which represent the commercial production in the dry land area, where fertilization and pest control are scarcely used. Landraces were classified according to the CONABIO guidelines for ear traits. Results: The measured accessions correspond to seven maize races and to seven interracial crosses. The two most frequent maize races were Ratón and Cónico Norteño, mainly located in the dry areas with less rain. Study Limitations/Implications: Three races, Celaya, Tablilla de Ocho and Elotes Cónicos, had not been previously reported; while two formerly reported races Tabloncillo and Olotillo, were no longer found. This study did not include the grain-colored accessions. Findings/Conclusions: Three collections stood out for producing large cobs with large kernels, thus showing a high yield potential. The maize landraces harvested in dryland areas might offer advantages to be grown under harsh environments or be used as gene donors for drought tolerance. [ABSTRACT FROM AUTHOR]

GRAIN yields , *BLOCK designs , *INBREEDING , *EXPERIMENTAL design , *HERITABILITY - Abstract
The specific (SCA) and general combinatorial aptitude (GCA) are used to identify hybrid combinations between inbred lines with higher or lower yield than that expected from the average behavior of the parental lines. The objective of this study was to evaluate the GCA of eight lines and the SCA of their inbreeding. We hypothesized that crosses between lines with contrasting characteristics would produce outstanding hybrids. During autumn 2011 the crosses were formed and in spring 2012 evaluated at the Marín experimental field, Universidad Autónoma de Nuevo León, México. The eight evaluated inbred lines were in a complete blocks experimental design at random with three repetitions. Genetic analysis was performed with the design II North Carolina mating from Comstock and Robinson. The progenitors, considered as males M-16 (4.74 t ha-1), M-11 (4.60 t ha-1) and M-14 (4.21 t ha-1) and females H-8 (4.26 t ha-1), H-2 (4.15 t ha-1) and H-4 (4.13 t ha-1) showed the greatest effects of GCA. Major effects on SCA were observed in the H-8×M-16 (4.99 t ha-1), H-8×M-11 (4.83 t ha-1) and H-2×M16 (4.78 t ha-1) crosses. The additive variance for grain yield was 0.03 and exceeded the dominance variance (-0.34); heritability in the strict sense was 7.65% and female variance (0.0075) was higher than that of males (0.0012).

The effects of suspensions of zinc oxide nanoparticles at concentrations between 100 and 500 mg L
−1 on germination of Capsicum chinense seeds and vigor of plants were evaluated using a randomized complete design with four replications, resulting in increased germination and improved development of lengths of plumule and radicle. The activities of peroxidase, catalase and ascorbate peroxidase were determined, showing that at all concentrations the activities of the former two enzymes were increased, whereas the activity of the latter was reduced at 500 mg L−1 . Pretreatments of seeds with ZnO nanoparticles can improve germination and development of seedlings and the activities of antioxidant enzymes. [ABSTRACT FROM AUTHOR]- Published

ETHANOL as fuel , *SORGO , *CLIMATE change - Abstract
Energy production from sorghum bioethanol is a way to help decrease climate change and environmental degradation. The objective of this work was to evaluate the agronomic characteristics associated to bioethanol production in experimental genotypes of sweet sorghum. During 2013 and 2014, seventeen sweet genotypes were evaluated in two locations, this locations are situated in northeastern Mexico, under a complete block randomly design with three replications. The three experiments were executed in Estacion Cuauhtemoc, Tamaulipas, in dryland; and two in Marin, Nuevo León, under irrigation. Experimental hybrid Potranca x Keller (p=0.05) presented the highest values (kg/ha) in: biomass weight (52 125), stem (39 650), panicle (4550), leaf (7700), juice (14 125), and bioethanol (2157 l/ha); it surpassed to the most productive control (Keller) in: 35,7, 32,5, 63,2, 41,6, 32,5, and 36,8%, respectively. It bloomed 6.8 days earlier than variety control. Experimental variety 17-1-1-1 had a minor foliar incidence of diseases in comparison to Keller. In addition, it presented agronomic characteristics similar to control in: biomass weight (44 375 kg/ha), stem (35 438 kg/ha), panicle (2488 kg/ha), leaf (6400 kg/ha), juice (11 750 kg/ha), plant dry weight (19 113 kg/ha), stem dry weight (14 888 kg/ha), bioethanol production (1929 l/ha), °Brix (15,2), days to flowering (80,8) and plant height (224 cm).

ARABINOXYLANS , *HYDROXYCINNAMIC acids , *CORN research - Abstract
In México, around 82% of the total production of maize is grown under rainfed conditions leading to a water stress environment which affects physiologic and biochemical process of the plant. Maize bran is a composited plant material consisting mainly in aleurone layer, testa and pericarp; the cell walls of these tissues are composed of proteins, non-starch polysaccharides, phenolic acids and lignin which are potential bioactive substances for human nutrition. In this research it was investigated the effect of water stress on cell wall components in the bran of three genotypes of maize by applying irrigation and water stress treatments. The content of protein, lignin, arabinoxylans, total phenols and phenolic acids was performed in the bran of 'Cebú', 'DK2027' and 'DK2034' genotypes. Water stress applied through grain development stage increased protein levels of 'Cebú', 'DK2027' and 'DK2034' in 4.05, 16.13 and 0.40% respectively. Respecting to lignin content, water stress increased levels at 1.28, 2.26 and 4.24% for 'Cebú', 'DK2027' and 'DK2034', respectively. Arabinoxylans content also increased in water stress treatment at levels of 1.28, 2.26 and 3.66% in 'Cebú', 'DK2027' and 'DK2034'. On the other hand, water stress treatment decreased the levels of total phenols and hydroxycinnamic acids in the three maize hybrids analysed. Reduction of total phenols was 35.34, 5.59 and 31.57% for 'Cebú', 'DK2027' and 'DK2034', respectively. In addition, the levels of t-ferulic, c-ferulic and p-coumaric acids decreased 17.74, 23.93, 29.83% in 'Cebú', 8.92, 8.62, 24.03% in 'DK2027' and 13.66, 11.03, 10.38% in 'DK2034' respectively.

Jatropha curcas is a species with a biodiesel production potential. The supply of elite planting material is critical due to traditional spread disadvantages. Plant tissue culture is an alternative to obtain quality plant material for planting. For these reasons, the objective of this study was to evaluate the feasibility of three phenological ages of petioles (1st, 2nd and 3rd node), and the effect of polyvinylpyrrolidone (PVP) on explants viability of the INI-3 and INI-6 genotypes of J. curcas and the petioles morphogenetic expression of the INI-6 genotype in two culture media (Yasuda and MS) with different doses of TDZ, BA and AIB. The in vitro establishment evaluated the PVP of the INI-3 and INI-6 genotypes with a completely randomized design (CRD) in a 2x2 factorial arrangement and 90 repetitions per treatment. The evaluated variables were viability and callus presence; viability was assessed with the Chi-square test (X
2 ) and the callus weight by an ANOVA. During the induction stage, two media culture added with TDZ, BA and AIB were evaluated in the INI-6 genotype due to their increased viability, in a DCA with a 2x2x2x3 factorial arrangement. Three replications, where the evaluated variable was the callus presence, using a logistic regression analysis (LRA). The results show that the viability is independent from the genotype, according to the X2 value (p=0.700), but dependent of the petiole type (p=0.019) and PVP addition (p = 0.001). The presence and callus production were influenced by the genotype expressed in the X2 and callus weight by an ANOVA. The induction stage showed that the AIB and TDZ are related to the callus presence based on the LRA. [ABSTRACT FROM AUTHOR]- Published

POLLEN ,GENE flow ,GENE flow in plants ,PLANT diversity - Abstract
Mexico, the center of origin of maize (Zea mays L.), has taken actions to preserve the identity and diversity of maize landraces and wild relatives. Historically, spatial isolation has been used in seed production to maintain seed purity. Spatial isolation can also be a key component for a strategy to minimize pollen-mediated gene flow in Mexico between transgenic maize and sexually compatible plants of maize conventional hybrids, landraces, and wild relatives. The objective of this research was to generate field maize-to-maize outcrossing data to help guide coexistence discussions in Mexico. In this study, outcrossing rates were determined and modeled from eight locations in six northern states, which represent the most economically important areas for the cultivation of hybrid maize in Mexico. At each site, pollen source plots were planted with a yellow-kernel maize hybrid and surrounded by plots with a white-kernel conventional maize hybrid (pollen recipient) of the same maturity. Outcrossing rates were then quantified by assessing the number of yellow kernels harvested from white-kernel hybrid plots. The highest outcrossing values were observed near the pollen source (12.9% at 1 m distance). The outcrossing levels declined sharply to 4.6, 2.7, 1.4, 1.0, 0.9, 0.5, and 0.5% as the distance from the pollen source increased to 2, 4, 8, 12, 16, 20, and 25 m, respectively. At distances beyond 20 m outcrossing values at all locations were below 1%. These trends are consistent with studies conducted in other world regions. The results suggest that coexistence measures that have been implemented in other geographies, such as spatial isolation, would be successful in Mexico to minimize transgenic maize pollen flow to conventional maize hybrids, landraces and wild relatives.

Chromatic, phenolic and antioxidant properties were evaluated in ten sorghum genotypes grown in Nuevo León, México. Lightness, Chroma and hue angle ranged from 64 to 83, 12 to 20 and 61 to 82 respectively, indicating that colour of the samples were located in the gray orange-yellow zone of the hue circle. Based on these results, samples were classified in three colour groups being Very Soft Orange, Slightly Desaturated Orange and Grayish Orange. Results in phenolics ranged from 796 to 15,949, 175 to 12,674 and 193 to 25,780 μgCE g-1 in total phenolics by Folin-Ciocalteu, total flavonoids by Aluminum Chloride and condensed tannins by Vanillin-HCl respectively. On the other hand, antioxidant capacity ranged from 1.20 to 93.83, 30.25 to 156.08 and 2.62 to 98.50 μ g-1 in 2,2-diphenyl-1-picrylhydrazyl, 3-ethyl-benzothiazoline-6-sulfonic acid and Ferric Reducing Antioxidant Power respectively. Significant differences (pE0.05) were observed in statistical analysis for both individual and group colour samples in chromatic, phenolics and antioxidant activity evaluations, showing 'Rox Orange' genotype and Grayish Orange colour group the highest levels.

Charcoal rot ( Macrophomina phaseolina) is a major disease of beans ( Phaseolus vulgaris L.) in Mexico. The use of germplasm combining high-yield stability with resistance to drought and charcoal rot could reduce damage from this disease. In this study, we compared the Eberhart and Russell method and the Additive Main Effect and Multiplicative Interaction (AMMI) model plus biplot analysis for measuring grain yield (GY) and charcoal rot resistance (CHRR) stabilities in 98 F
8 : 10 recombinant inbred lines (RILs) derived from a cross between bean adapted to the tropics (BAT) 477 (resistant) × Pinto UI-114 (susceptible). Experiments were conducted from 2007 to 2009 in Isla, Cotaxtla, Río Bravo and Díaz Ordaz, México, under irrigated or terminal drought conditions. anova detected significant differences (P ≤ 0.05) in GY and CHRR among environments, genotypes and genotype × environment interactions (GEI). Most RILs showed good responses to unfavourable environments based on GY (48) and CHRR (40). AMMI anova s for both traits showed that all sources of variation in the model accounted for approximately 49% of the total squared sum. For the first principal component (PC1), we found 13 RILs that were stable for GY, and for the second (PC2), we found 9 that were stable for GI. For CHRR, we detected 14 stable RILs (PC1) and eight (PC2). Biplot analysis showed the largest vectors for Díaz Ordaz (irrigated and drought, 2008), where the highest and most variable GYs were detected. The shortest vectors were found in Isla (drought, 2007) and Río Bravo (irrigated and drought, 2008), where the lowest and least variable GY were found. We found differential responses of RILs to locations, years and soil humidity conditions as well as significant GEI based on GY and CHRR. The two methods were complementary, and both gave us information to select stable, high-yield germplasm associated with resistance to charcoal rot disease. [ABSTRACT FROM AUTHOR]- Published

CORN varieties , *AGRICULTURE , *PHENOTYPES ,CORN genetics - Abstract
The objective of this work was to identify the molecular and phenotypic variability among maize populations Pinto Amarillo and Liebre in Nuevo Leon, Mexico. The phenotypic characterization experiment was established in spring 2009. The variables registered were plant height, days to male and female flowering, number of rows per ear, kernels per row of ears, length and diameter of the corn ear. For the molecular characterization of the 30 populations, the seeds were planted in February 2010 in pots with peat-moss. At 30 days after planting all the leaves were collected and used in AFLP. A cluster analysis was conducted using UPGMA method. Three groups were identified; twelve populations of Pinto Amarillo and three of Liebre. The landraces within each group were associated more to races of maize more than to location. [ABSTRACT FROM AUTHOR]

The objective of the study was to determine if the introgression of exotic sorghum lines increases the variability in the size of the glume and in the percent of uncovered grains. The sorghum population NESC7 (P1) was formed during four agricultural cycles (2005-2007) with an introgression cycle, and beginning on the fifth agricultural cycle (2008), the genetic variability for these traits was estimated in the 120 half-silb and 110 self-sib families. The methodology of incomplete block design was used at two locations, the Faculty of Agronomy at the University of Nuevo Leon (FAUANL) in Marín Nuevo Leon and INIFAP in Río Bravo, Tamaulipas. The introgression of exotic lines with smaller glume size and reduced grain cover into the population NESC7 (P1) reduced the size of the (13%), increased the percentage of uncovered grain (28%), and increased the proportion of both characteristics in the additive variance (5% and 1%), the heritability in a narrow sense of 22 % and 1% and higher response to selection (4% y 0.3%).

Sorghum (Sorghum bicolor (L.) Moench) is cultivated in regions with frequent drought periods and high temperatures, conditions that have intensified in the last decades. One of the most important photosynthetic components, sensible to hydric stress, is maximum quantum yield for photosystem II (PSII, or Fv/Fm). The objective of the present study was to identify sorghum genotypes with tolerance to hydric and heat stress. The treatments were hydric status (hydric stress or non-hydric stress (irrigation)), the plant's developmental stages (pre or post-anthesis), and six genotypes. The response variables were Fv/Fm; photosynthetic rate (P
N ); stomatal conductance (gs ); transpiration rate (E); relative water content (RWC); damage to cell membrane (DCM) at temperatures of 40 and 45 °C; and agronomic variables. The experiment was conducted in pots in open sky in Marín, N.L., in the dry and hot northeast Mexico. The treatment design was a split–split plot design, with three factors. Hydric stress diminished the functioning of the photosynthetic apparatus by 63%, due to damage caused to PSII. Pre-anthesis was the most vulnerable stage to hydric stress as it decreased the weight of grains per panicle (85%), number of grains per panicle (69%), and weight of 100 grains (46%). Genotypes LER 1 and LER 2 were identified as tolerant to hydric stress, as they had lower damage to PSII; LER 1 and LEB 2 for their superior RWC; and LER 1 as a thermo tolerant genotype, due to its lower DCM at 45 °C. It was concluded that LER 1 could have the potential for both hydric and heat stress tolerance in the arid northeast Mexico. [ABSTRACT FROM AUTHOR]- Published

Maize is the most important crop around the world and it is highly sensitive to abiotic stress caused by drought, excessive salinity, and extreme temperature. In plants, trehalose has been widely studied for its role in plant adaptation to different abiotic stresses such as drought, high and low temperature, and osmotic stress. Thus, the aim of this work was to clone and characterize at molecular level the trehalose-6-phosphate synthase (TPS) and trehalose-6-phosphate phosphatase (TPP) genes from maize and to evaluate its differential expression in maize seedlings under drought stress. To carry out this, resistant and susceptible maize lines were subjected to drought stress during 72 h. Two full-length cDNAs of TPS and one of TPP were cloned and sequenced. Then, TPS and TPP amino acid sequences were aligned with their homologs from different species, showing highly conserved domains and the same catalytic sites. Relative expression of both genes was evaluated by RT-qPCR at different time points. The expression pattern showed significant induction after 0.5 h in resistant lines and after two to four hours in susceptible plants, showing their participation in drought stress response.

The physiological responses of habanero pepper plants (Capsicum chinense Jacq.) to foliar applications of zinc sulphate and zinc nano-fertilizer were evaluated in greenhouse trials. The effect of the supplement on fruit quality of habanero pepper was particularly observed. Habanero pepper plants were grown to maturity, and during the main stages of phenological development, they were treated with foliar applications of Zn at concentrations of 1000 and 2000 mg L
−1 in the form of zinc sulfate (ZnSO4 ) and zinc oxide nanoparticles (ZnO NPs). Additional Zn was not supplied to the control treatment plants. ZnO NPs at a concentration of 1000 mg L−1 positively affected plant height, stem diameter, and chlorophyll content, and increased fruit yield and biomass accumulation compared to control and ZnSO4 treatments. ZnO NPs at 2000 mg L−1 negatively affected plant growth but significantly increased fruit quality, capsaicin content by 19.3%, dihydrocapsaicin by 10.9%, and Scoville Heat Units by 16.4%. In addition, at 2000 ZnO NPs mg L−1 also increased content of total phenols and total flavonoids (soluble + bound) in fruits (14.50% and 26.9%, respectively), which resulted in higher antioxidant capacity in ABTS (2,2′azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), DPPH (2,2-diphenyl-1-picrylhydrazyl), and FRAP (ferric reducing antioxidant power) (15.4%, 31.8%, and 20.5%, respectively). These results indicate that application of ZnO NPs could be employed in habanero pepper production to improve yield, quality, and nutraceutical properties of fruits. [ABSTRACT FROM AUTHOR]- Published

The growing global demand for energy and the reduction of energy based on oil are driving the search for new sources of energy that are environmentally friendly. To achieve this goal, it is also necessary to optimize the related processes. In this study, the behavior of the agronomic parameters of, and the energy invested in, production systems based on a new variety of sweet sorghum (Sorghum bicolor (L.) Moench) called ROGER were determined to define the optimal production conditions. To this end, three methods of tillage (minimum, traditional, and traditional tillage with rupture of the plow layer) and three types of fertilizers (inorganic, organic, and without fertilizer) were established, and to estimate the energy efficiency, the inputs and the energy outputs of each system were considered. The traditional tillage with breaking of the plow layer and the organic fertilizer showed the highest values of plant height (2.45 and 2.39 m, respectively); total fresh weight of the plant (51.66 and 50.77 t·ha
−1 , respectively), of the stem (42.7 and 41.05 t·ha−1 , respectively), and of the juice (21.89 and 22.57 t·ha−1 , respectively); the volume of the juice (20,783.12 and 22,529.59 L·ha−1 , respectively); and Brix degrees (16.04% and 15.01%, respectively). However, the highest energy efficiency was registered in the production system that used the minimum tillage, with a value of 15.11, as well as when no fertilizer was applied with 18.68.

The effects of zinc oxide nanoparticles on seed germination and seedling growth of Capsicum annuum L. were determined in this research. Total phenols content, total flavonoids, and condensed tannins, as well as 2,2-diphenyl-1-picrylhydrazyl (DPPH) antioxidant capacity was determined. Results indicated that treatment with zinc oxide nanoparticles (ZnO-NPs) improved seed germination rate during the first seven days. The seed vigor germination increased 123.50%, 129.40% and 94.17% by treatment with ZnO-NPs suspensions at 100, 200 and 500 ppm, respectively. The morphological parameters tested revealed that ZnO-NPs treatments did not significantly affect plumule development, but they had a significant impact (p ≤ 0.01) on radicle length. Suspensions at 100, 200 and 500 ppm of ZnO-NPs inhibited seedling radicle growth and promoted accumulation of phenolic compounds, with a phytotoxic effect in this organ. Results suggested that zinc oxide nanoparticles influence seed vigor and seedling development and promoted the accumulation of desirable phenolic compounds in the radicle. [ABSTRACT FROM AUTHOR]

The objective of the study was to evaluate the agronomic performance of A, B isogenic lines and R grain sorghum lines which restore androfertility of sorghum for grain production. This work was performed during the spring-summer 2010 in Marin Nuevo Leon under drip irrigation. Days to flowering, seed yield per plant, brix degrees and weight of 1000 seeds were measured. The statistical analysis with the benchmark test of averages with independent samples was realized in A, B sorghum lines to days to flowering, seed yield per plant, brix degrees and weight of 1000 seeds. In R lines the analysis of variance and DMS (P<0.05%) test was performed. A an B lines were not completely isogenic; there are A and R lines that may be crossed to produce commercial sorghum grain seed. B and R lines might be used as varieties and A, R parental lines planting splits were defined to produce hybrid sorghum seed. [ABSTRACT FROM AUTHOR]

SORGO , *BIOMASS production , *SORGHUM , *ORGANIC fertilizers , *TILLAGE - Abstract
Sweet sorghum (Sorghum bicolor [L.] Moench) is a crop that is well known for its high production of biomass and sugars in the stem juice. The objective of this work was to evaluate the productivity of sweet sorghum 'Roger' based on the dynamics of sugar production and dry biomass by considering different production methods and plant phenological stages. The experimental design consisted of different tillage and fertilization methods established in a randomized complete block design with a split plot arrangement. Tillage treatments were assigned to the plot using the three levels of minimum tillage, traditional tillage, and traditional tillage that included a subsoil operation. Fertilization treatments were assigned to the subplot using the three levels of organic fertilizer, inorganic fertilizer, and without fertilizer. Data collection was performed at different plant phenological stages from anthesis to physiological maturity. Results showed that evaluated agronomic parameters depended on the phenological stage (P < 0.05) rather than the production methods (P > 0.05). Thus, the distribution and accumulation of sugar by stem internodes was associated with plant phenological components. The highest values of the concentration of total soluble solids (14.89%), juice sugar content (22.91 g), juice sugar concentration (527.46 mg g-1 DW), dry biomass (60.04%), and dry biomass yield (19.01 t ha-1) were observed at the physiological maturity stage of the plant.

Charcoal rot caused by Macrophomina phaseolina (MP) is the most important disease that limits sorghum dryland production in northern Tamaulipas, Mexico. Grain yield losses caused by MP are approximately 30%. The objective of this study was to evaluate the response of experimental and commercial hybrids to MP and identify MP tolerant progenitors. Experimental hybrids RB-118 x 435 and RB-27 x 437 showed MP tolerance and grain field similar to commercial checks Pioneer 82G63, Pioneer 84G62, RB-Patrón, Asgrow Z- 400, RB-3030, and DK-47, and greater than Asgrow-Ámbar. Progenitor females that produced tolerant MP hybrids were LRB-118 and R-27, and males Tx-435 and Tx-437. [ABSTRACT FROM AUTHOR]
