Abstract: Effects of abscisic acid and uniconazole on photosynthetic characteristics of strawberry under drought stress were studied. The results showed that abscisic acid and uniconazole could increase water use efficiency obviously compared to CK2, net photosynthetic rate、transpiration rate、 stomatal conductance and intercellular CO2 concentration also changed a lot. Different exogenous hormones have different degree on photosynthetic parameter of strawberry, but which could all improve the ability of anti-drought stress of strawberry. The suitable exogenous hormones concentration range for application: abscisic acid is 1mg/L~4 mg/L, uniconazole is 25mg/L~100mg/L.
