Alterations in cellular membrane stability due to heat stress in different genotypes of bread wheat
Heat stress due to increase in temperature is an agricultural problem in many parts of the world. The objective of the present study was to examine changes in cell membrane stability when leaf samples of similar size of biological replicates from a single genotype of different varieties of wheat were exposed to varying temperatures (45°C and 100°C).The highest per cent of conductivity was observed in HDR77 as compared to remaining eleven varieties (HD 2864, HD 2967, PBW 373, HS 365, Raj 4037, JAUW 584, PBW 175, RSP 561, HW 2045, HD2385, HD2687) which predicts that highest susceptibility of this variety and least per cent of conductivity was seen in HD 2687 which predicts that it is highly resistant variety.
