Abstract
Data are presented on the features of winter wheat adaptation (Triticum aestivum L., cultivar Moskovskaya 39) to frost as a result of low hardening temperatures of varying intensity. A comparative analysis of the dynamics of indicators characterizing frost resistance, growth, transpiration rate, the intensity of oxidative processes, the state of the photosynthetic apparatus, the structure of leaf cells, and the level of WCOR15 gene transcripts (coding for a cold response protein) was carried out during hardening of wheat plants at temperatures of 12, 8, and 4°C. It is shown that, during cold adaptation, the “reprogramming” of the plant organism occurs, the degree and depth of which are determined by the intensity of low-temperature exposure: the closer the hardening temperature is to damaging values, the faster and more significant adaptive changes it causes, and the greater frost resistance plants are able to develop in the process of hardening.
