Abstract

Salt stress decreases plants crop growth including RICE. This research was carried out to evaluate responses of RICE genotypes to salt stress using a factorial experiment with randomized complete block design in three replications, at Dankook University, South K+orea in 2012: First factor was 16 RICE cultivars at vegetable growth stage and second factor was soil salinity levels (0.8 ds m-1 as control and 6.2 ds m-2 ). Salt stress disturbed cell membrane stability. The highest shoot dry weight was decreased in IR67075-2B-5-2 (153.8 g m-2), K+ochihibic (152.2 g m-2), Haraz (149.8 g m-2), Shafagh (152.0 g m-2) and Nemat (156.9 g m-2) cultivars. These cultivars showed maximum K++/Na + rate, ANTIOXIDANT ENZYMEs activates, relative water cotent, soluble carbohydrate and photosynthesis rate and minimum leaf NA++ concentration. Results indicated IR67075-2B-5-2, K+ochihibic, Haraz, Shafagh and Nematwere salt tolerante cultivars compared with other RICE cultivars.
