| Abstract: | The effect of root-applied glycinebetaine(GB) on the root growth and photosynthetic characteristics in maize seedlings under salt stress was investigated in sand culture in the present study.The results showed that root-applied glycinebetaine(10mmol·L-1) could ease the damage of salt stress on maize seedlings,promote its growth,make root elongation,impove water regime and plasma membrane permeability of root and increase photosynthesis. |
