Abstract

Weather anomalies of recent years show that in Kazakhstan, special attention should be paid to increasing plant tolerance to temperature stress. The article provides information on changes in weather and climatic conditions in the winter-growing regions of Kazakhstan. In the Almaty region, in 2021-2023, an increase in air temperature during the growing season was noted by 1.73-2.60 °C compared to the average annual data. In the region, during the vegetation period, there is a decrease in precipitation and rainfall is uneven. The main indicators of drought tolerance in modern varieties of winter wheat and methods of their study are shown. Based on the literature data and our own research, the influence of the parameters of the flag leaf (length, width, area), leaf rolling during drought, slowing down the aging of "Stay-green" plants, drooping and waxy coating of plants on the drought tolerance of winter wheat has been established. Winter wheat varieties were evaluated according to productivity indicators in conditions of natural drought. It was noted that due to the warming of the climate in the region, it is necessary to continue research on the drought tolerance of winter wheat on the signs of bushiness, vegetation period, plant height, length of the upper internode of the stem, area of the flag leaf, twisting of leaves, wax coating, as well as on the NDVI index of plants during drought.
