Adaptogenic Preparations Enhance the Tolerance to Spring Frosts, Yield and Quality of Apple Fruits

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