| Abstract/Description: | To investigate the effect of water stress on relative water content, antioxidant enzymes (Superoxide Dismutase activity and Peroxidase) and membrane leakage in twelve genotypes of sunflower a study was conducted during rabi, 2010-11 at College Research Farm, ANGRAU, Hyderabad. Water stress was imposed at flower bud initiation stage by withholding water 20 days from 40 DAS to 60 DAS, whereas, the control plots were irrigated at 10 days intervals throughout the crop growth period. With increase in stress duration RWC decreased in all the genotypes examined. However, genotype SH-177 recovered quickly from stress by maintaining high RWC. Antioxidant enzymes i.e., superoxide dismutase activity and peroxidase activity increased with stress duration and age of crop. Membrane leakage increased with stress duration and age of the crop indicating membrane damage is irreversible process. SH-177 for RWC, TSF-106 and DSF- 104 for SOD activity, DSF-111 for POX activity and ASF-107 for membrane integrity are considered as promising lines to be used in drought resistance breeding programme. |
