| Sumario: | One of the main factors increasing the productivity of vineyards and the quality of fresh grapes during storage is the use of vegetative treatments with bioregulators of various physiological effects. This work is devoted to the study and comparative assessment of various foliar treatments with the growth regulator "Albit", "Glycerol" and a complex of fertilizers LLC "Biochefarm Rus" on agro biological and commercial quality characteristics of the table grape variety ‘Moldova’ during the longterm storage. Foliar treatments were carried out in the main phases of the growing season: 'before flowering', 'after flowering', 'the beginning of growth', 'the beginning of ripening'. Sampling for analyzes was carried out for 30, 90 and 150 days of storage. It was found that foliar treatment leading to a significant increase in cropping capacity of grapes by 26.8% ("Biochefarm"), 36.5% ("Albit") and 20.0% ("Glycerol"). The increase in the average weight of the bunch in the experimental variants grew by 29.6-31.3%. The use of experimental schemes of foliar treatments made it possible to increase the keeping quality of table grapes: the weight loss of bunch decreased by 0.3-3.5%. The tasting assessment of the experimental batches of grapes at the end of storage exceeded the control by 5.6-6.9%. |
