EFFECTS OF COLD STRESS ON SOME PHYSİOLOGİCAL FEATURES OF WHEAT CULTIVARS

Cold acclimation process is an essential mechanism in wheat cultivars’ tolerance to cold stress. Results of FLN measurements indicated no vernalization requirement for Kavir spring wheat and vernalization fulfillment after 42 days of vernalization cold for Marthon winter wheat. Measurements of LT(50) showed that maximum cold tolerance during vernalization fulfillment for Marthon and Kavir cultivars were -17 and -2 C, respectively.
