Abstract
Wheat(cv.Liaoda 091) was used as the material,effects of exogenous GABA at different concentration levels were studied on the germination characters and physiological indexes of wheat seedlings under NaCl-stress,such as germination percentage,bud length,root length,fresh weight,dry weight,relative conductivity and enzyme activity.The result indicated that seeds soaked with GABA promoted the growth of seedling;however,a little effect on growth of root when compared with the control.GABA at 0.5 mmol·L-1 significantly increased germination rate and the fresh dry weight of wheat seedling.The result of relative conductivity showed that GABA at different concentration had a varying degree protective for membrane,the concentration at 0.5 mmol·L-1 had the maximum protection.GABA enhanced the activity of SOD,POD and CAT,the activity of the enzymes increased along with the concentration of GABA.It is suggested that extraneous GABA could decrease NaCl-stress of wheat seedlings by increasing protection of membrane.
