Effect of seed aging and hormonal priming on different physiological attributes in french bean

Use of aged seed is one of the main factors in athining lower plant yield loss. If proper seed storage facilities are not available it increases the process of seed viability and vigour loss. To assess the effects of aging on seed vigour and viability a laboratory experiment was initated by artifically ageing the seed at high temperature (45°C) and high RH (in 100%). Also, the efficiency of priming treatment was tested in improving the quality of acculated aged seeds of French bean. Our result showed that seed priming treatments significantly (pd” 0.01) affected germination percentage and other growth parameters. Seed priming with 5ppm GA3 was found beneficial in improving seed germination in accelerated aged seeds of French bean. Priming with IAA and kinetin was not found effective in improving germination and other growth parameters in aged seeds of French bean.
