Abstract

The goal of the research is to study the effectiveness of the use of adaptogenic preparations of the Natural Plant Complex “White Pearl” line to increase the yield and quality of apples. The objects of the studies were the apple cultivar “Sinap Orlovsky” and adaptogenic preparations: phytomodulator “White Pearl Universal Antifreeze” and phytocorrector “White Pearl Drip Ca + Mg”. The experiment used the following variants: 1—control (foliar sprays with water); 2—foliar sprays with adaptogenic preparations: 1% solution of “White Pearl Universal Antifreeze” + 1% solution of “White Pearl Drip Ca + Mg”. As a result of the complex use of biological products, the yield was significantly increased by 1.7 times and the average fruit weight was increased by 20.3 g. The adaptogenic preparations increased the yield of marketable apple fruits by 14.8% and contributed to a 2.5-fold decrease in fruits affected by scald and a 2-fold decrease in bitter pitting. The adaptogenic preparations improved the taste qualities of “Sinap Orlovsky” fruits compared to the control by increasing the amount of sucrose by 25.6% and ascorbic acid by 20.5%. The conducted tests of adaptogenic preparations in apple plantations show the prospects of their use as additional techniques in traditional apple cultivation technologies.
