The influence of cold hardening on heat generation in winter wheat seedling shoots during cold stress is discussed. In seedling winter wheat shoots, the temperature of "living" plants was higher, than in the ones "killed" during short-term low-temperature stress (cold shock). The study of the influence of cold shock intensity has shown that an increase in cold shock intensity caused a larger temperature difference between "living" and "killed" seedling shoots and resulted from an increase in thermogenesis in winter wheat seedling shoots. Cold hardening reduced this temperature difference between "living" and "killed" winter wheat seedling shoots. Treatment of winter wheat shoots by an uncoupling agent (CCCP) caused both an increase in temperature and survival during cold shock.
