The bioecological characteristics of some apple tree (

In the article, the biological characteristics of the Red apple, Hayat, Oydin, Borovinka Tashkentskaya, and Chulpan varieties of apples introduced from abroad for the first time in the conditions of the Karshi oasis were studied. In the observed year, as a result of a sudden change in the weather, from January 7 to January 30, 2023, the temperature dropped sharply to -300C. In March, the air temperature was higher than +100C. In this case, all observed cultivars flowered well and produced fruit set. Branches and shoots damaged by frost were not observed. In June and July, the air temperature rose to +500C and this hot weather lasted for 15 days. After 6 days, 2% of the apple leaves in the middle layer turned yellow and fell off. The fruits were not damaged by the heat. These observations show that the introduced apple varieties are suitable for Kashkadarya soil and climate conditions. The discussion was supplemented by the opinions of scientists about the healing properties of apples.
