Abstract

The low temperature is one of the most important factors limiting the growth, production and geographical distribution of plants. This stress may occur as chilling, freezing, and late spring low temperature. In spring, simultaneously with the beginning of wheat growth, tolerance to low temperatures is reduced and may be faced with decreasing temperature at any stage of its growth and damaged. This type of sudden temperature drop in spring is known as late spring frost. This investigation evaluated cell membrane stability in selected cultivars of bread wheat that affected by late spring low temperature, in 50-68 Zadoks codes. The experiment was carried out in a randomized complete block design with two factors, 13 cultivars and three late spring low temperature treatments including +8 (control), 0, and -2°C. Membrane lipid peroxidation and electrolyte leakage were analyzed as the most cell membrane stability indices. Regarding to significant differences at the 5% probability level for genotype × stress interactions in traits, comparison of means showed that there were various responses among the cultivars. Finally, based on the results, cv. Pishgam was assessed as resistant and cv. Sivand susceptible to late spring low temperature according to the amounts of measured indices.
