Abstract:

Heat stress one of the Environment stress comes under Abiotic stress. Heat stress is the major problem for wheat crops in the current climate whether as a result of increasing global warming. These changes affect negative possessions on crops such, physiological aspects. In that study, there are taken various physiological parameters for twelve wheat genotypes viz DBW17, PBW343, DBW71, DBW16, WH711, RAJ3765, PBW373, PBW502, C306, WH730, PBW233, and WH157.The chlorophyll content and photosynthetic rate, decrease in high temperature (37ºC). Chlorophyll content average was 37.99 µg/cm2 in treatment and in control condition the average was 33.43µg/cm2. While average value of Photosynthetic rate was 18.98 µmol/m2sec in control compared to treated plants (16.66 µmol/m2sec) was lower at 37°C. The physiological parameter as Relative water content decreased in high temperature (37ºC). Plants at ambient temperature (22±2°C) showed higher average RWC 83.02% then treated plants average 78.29 % at 37°C. The injury% of cell membrane stability, genotype RAJ3765 was shown less injured at high temperature (37°C). Here showed minimum% injury was 62.42% of Cell membrane stability at 37 ºC. Therefore, from above results, it could be identified the heat-tolerant genotypes in wheat which performed a good role at physiological parameters under heat stress.
