Abstract
In order to study the salt tolerance of wild soybean and physio-ecological responses while they are under salt stress.Seedlings were transferred with 0,50,100,150 and 200 mmol·L-1 of NaCl solution, and determined related indexes. The results showed that there was no significant effect on the growth of wild soybean under low concentration of NaCl. While under severe stress or time prolonging, the growth rate of fresh weight was slower, water content ratio reduced, root-shoot ratio increased ,the content of soluble sugar increased quickly but it decreased a little later, the content of soluble protein increased at first and then decreased, the content of Prolineand malondialdehyde (MDA) content increased. The results indicated that the wild soybean had certain salt tolerance ability. Root-shoot ratio, water content ratio, the content of soluble sugar, soluble protein, MDA and Protine could be used as important indices for reflecting the salt tolerance of wild soybean.关键词
