Evaluation of chickpea genotypes for heat stress under elevated temperature
Author(s): Adishesha and VP Chimmad
Abstract: An experiment was conducted to study the short time exposure of high temperature during flowering period to six chickpea genotypes. Chickpea plants were exposed to high temperature (34.37/15.10 ºC) and control (30.90/13.50 ºC) for 10 days at flowering stage. High temperature stress significantly decreased pollen fertility percentage (21.12%) and pollen germination percentage (45.77%) compared to optimum temperature or control (53.45% and 66.04%) respectively. High temperature also significantly reduces the plant height (24.97cm), total dry matter (8.277 g plant-1) compared to control (28.05 cm and 14.55 g plant-1) respectively whereas, high temperature stress significantly increased the antioxidant enzymes such as peroxidase (0.788 µmoles min-1mg-1 of protein) and superoxidase dismutase (67.28 U/mg protein) enzyme activity compared to control (0.442 µmoles min-1mg-1 of protein and 34.85 U/mg protein), respectively.
