The use of biostimulants in plant production is an agricultural practice friendly to environment and one of the tools employed in the sustainable agriculture. The present paper was to determine the influence that the application of products based in oligosaccharines exerted on plant growth and development of garlic (Allium ampeloprasum L.) cv. 'Fredy'. The present work was performed, under field conditions, during the period October 2020 - February 2021 with the objective of determining the influence of the application of products based in oligosaccharines on the growth and development of elephant garlic plants (Allium ampeloprasum L.) cv. 'Fredy'. The effect of determined doses of QuitoMax® and PectiMorf® products, in different ways of application ("seed" imbibition, foliar spray at 80 DAP and the combination of both with the particularity was evaluated of also, combining the products) on the behavior of emergence percentage at 7 and 14 DAP. Besides, plant height (cm) and leaf number at 70, 90 and 110 DAP; as well as, the bulb characteristics and the survival percentage at harvest time was evaluated too. In addition, plant yield was estimated. Results shown that, in general, the application of QuitoMax® was more efficient than that of PectiMorf® in stimulating all the indicators evaluated, although the best results were obtained when both products were used in combination, that is, the "seed" imbibition with QuitoMax® and the foliar spray of the plants with PectiMorf® or viceversa.

The elephant garlic (Allium ampeloprasum L.) was introduced in Cuba, but it is not known who brought it. It is adapted to production and climatic conditions in the western part of the country, between October and February. With low inputs, it is resistant to diseases and reaches yields higher than 24.89 t ha-1 when planting is done mechanized and the "seed" is planted at 0.70 m of row, two rows and 0.07 m between plants, with which it reached between 15.10-15.0 t ha-1. This new garlic species has good post-harvest quality and adaptability in the areas studied. [ABSTRACT FROM AUTHOR]

QuitoMax® is a Cuban biostimulator of growth that could be used to reduce rooting and survival problems in pepper. The aim of this work was to determine the effect of QuitoMax® on the acclimatization of pepper plantlets (Capsicum annuum L.) cultivar 'YAMIL'. Plantlets from the in vitro multiplication stage, without roots, were used. Plantlets were soaked in QuitoMax® (1-10 mg L-1) or AIA (2 mg L-1) and sprayed 15 days later with the same concentrations; a control treatment was used in which plantlets were neither soaked nor sprayed. Planting was carried out in polyethurane trays containing a substrate composed of organic matter (cachaça) and eutrophic compacted Red Ferrallitic soil. A completely randomized design was used and the experiment was repeated three times over time. Data were processed using a Simple Ranked Analysis of Variance (ANOVA) and the comparison between means was performed according to Tukey's test (p>0.05). Treatments 2 [IAA (2 mg L-1)], 3 [QuitoMax® (1 mg L-1)], 4 [QuitoMax® (5 mg L-1)] and 5 [QuitoMax® (10 mg L-1)] achieved survival ranging from 90-100 %. All treatments with QuitoMax® showed the most vigorous plants and those with the greatest height were those with the lowest concentration of the product. The number and length of roots were similar in the treatments with AIA (2 mg L-1) and QuitoMax (1 mg L-1). [ABSTRACT FROM AUTHOR]

Pepper (Capsicum annuum L.) is a species of great demand condiment; it is rich in lycopene and antioxidants. 'YAMIL', is a pepper cultivar recently obtained through the Genetic Improvement Program at "Liliana Dimitrova" Horticultural Research Institute in Mayabeque, Cuba, of good performance against the effects of climate change and phytopathogenic diseases. This work was aimed to evaluate the effect of QuitoMax® at in vitro propagation and acclimatization phases on seedlings of 'YAMIL' pepper cultivar. During the in vitro phase, the growth biostimulator was applied at different concentrations (1-10 mg/L) alone or in combination with 6-BAP (2 mg/L). At acclimatization, plantlets' roots were embedded in this product and 15 days after planting they were sprayed at the same concentrations. In this phase the same procedure was carried out with indole acetic acid (IAA; 2 mg/L). A completely randomized design was used, data were processed by simple ANOVA and the means were differentiated using the Tukey's test (p ≤ 0.05). A good response of explants was demonstrated using this growth biostimulator, regardless the concentration used. Best results were attained with basal culture medium MS supplemented with 1 mg/L QuitoMax®. In the acclimatization phase, best results were obtained when the roots were immersed and subsequently sprayed with QuitoMax® (1 mg/L) at the same concentration as in the in vitro phase. The use of QuitoMax® both in vitro and in the acclimatization phase favored the different variables evaluated. [ABSTRACT FROM AUTHOR]
