Drought Resistance of Soybean Seedlings Induced by NaCl Pretreatment

Xu Fenfen;Guo Dingsheng;Wang Nan;Life Science College, Shangrao Normal University;  
In order to explore the effect of salt pretreatment on drought resistance of soybean seedlings, the influence of NaCl pretreatment on drought resistance of salt-tolerant soybean seedling ‘early-maturing soybean'and salt-sensitive seedling ‘No.1 soybean'were studied by pretreating soybean seedlings with 0.6% NaCl, and then simulating the drought environment by 100 g/L of PEG-6000. The results showed that the growth and root hair development of soybean seedlings were inhibited by PEG stress, and the activity of protective enzymes was reduced while the accumulation of reactive oxygen was increased. Moreover, the reduction of root hair length,diameter, main root length, plant height and protective enzyme activities of the salt-tolerant variety‘earlymaturing soybean'were higher than those of salt-sensitive variety‘No.1 soybean', and its increase of reactive oxygen was lower compared with salt-sensitive variety ‘No.1 soybean'. The inhibition of root growth of two varieties were eased, the protective enzyme activity was improved, and the amount of accumulation of active oxygen was reduced after NaCl pretreatment.
