PLANT ECOPHYSIOLOGY (ARSANJAN BRANCH)
توضیح
In order to study the effects of SALT STRESS on MORPHOLOGICAL AND PHYSIOLOGICAL TRAITS of some Glycine max (L.) cultivars, an experiment was conducted as factorial based on a completely randomized block design with three replicates in Shiraz in 2010. In this experiment the first factor was cultivars treatment: Sahar, BP and Sari JK and the second factor was salinity treatment including four levels: 0, 25, 50 and 75 mmol NaCl. The experiment soil was sandy and used the Hogland solution without nitrogen as fertilizer. Data were analyzed by SAS program procedure and means comparisons were tested by LSD in 5% level statistically. The Results showed that leaf area, shoot dry weight, root dry weight, shoot wet weight and height decreased by increasing the salinity levels. The highest leaf area in all salinity levels was for Sari JK cultivar and the lowest was for BP cultivar. By increasing SALT STRESS, Sari JK had the most shoot and root dry weight, in the three cultivars. Results also indicated that, in shoot wet weight and height, Sari JK and Sahar cultivars were better than BP. In general, it seems that Sari JK was the best cultivar of the three against SALT STRESS.
