Experiments have been conducted to investigate the effects of exogenous betaine on drought resistance of wheat and eggplant. The results indicated that the germination percentage, photosynthesis intensity [being 7. 07-7. 57μmol/(s·m2)] and biomass production of wheat were increased when the concentration of exogenous betaine was between 25 mg/L and 50 mg/L. Activity of nitrate reductase in wheat leaves reached the maximum value 35. 23μg/(g·h), and the drought resistance of wheat could be enhanced when the c...
