Apple is the main fruit crop of Ukraine. To obtain stable high-quality harvests of this crop, the use of foliar top dressing is a prerequisite. Also for the formation of a qualitative crop in the context of quantitative and qualitative characteristics and to reduce the negative influence of environmental factors, it is necessary to use plant antistress agents, such as film-forming agents, amino acids and the like. A study conducted on the effect of AminoBrix on the accumulation of dry substances in apple fruits. It was found that when processing with a 1% solution of AminoBrix, the solids content increased by 0.4, 0.96 and 1.12% for Florina, Topaz and Remo varieties, respectively, while processing with a 2% solution increased by 0.48, 0.98 and 1,17% respectively for varieties Florina, Topaz and Remo. It also found that with a dynamic increase in the content of dry matter, the total content of pectin substances remained at the same level for all the varieties under study, in comparison with the control. Namely, for the Topaz variety 1.07, for the Florina variety 0.875 and for the Remo variety 1.095, pectin substances, namely, the content of hydrate-pectin increased and was 0.18 (+ 11%) for the Topaz variety, 0.23 (+ 9%) for the Florina variety, and 0.14 (+ 5%) for the Remo variety. There was no significant difference between treatment options for 1 and 2% solution of AminoBrix.
