| Abstract: | A pot experiment on effects of salt stress on photosynthetic physiology and chlor ophyll fluorescence characteristics of 1-year old grape(Red Globe) seedlings was conducted.The seedlings were treated with NaCl concentrations of 0.1,0.2, and 0.3 g/kg,and with fresh water as the control.The results showed that with treatment time increasing,the net photosynthetic rate,transpiration rate,stomatal conductance and the leaf chlorophyll concent ration all decreased.Furthermore,the determination of chlorophyll-fluo... |
