摘要：
A pot experiment was conducted to study the effects of photosynthesis of Chinese cabbage under NaCl stress, and different concentrations of abscisic acid (ABA) solution about 1, 5, 10 and 20 mu mol.L-1 was sprayed, control was sprayed water on leaves. The results showed that spraying ABA could improve net photosynthetic rate (Pn), stomatal conductance (Gs), water use efficiency (WUE), light use efficiency (LUE), transpiration rate (Tr) and CO2 concentration of intercellular (Ci) of Chinese cabbage under NaCl stress, thereby enhanced the photosynthetic capacity. Therefore, spraying exogenous ABA can improve the resistance of NaCl stress of Chinese cabbage, and the ABA concentration of 10 mu mol.L-1 worked best.
