| Abstract: | Effects of exogenous gibberellin and salicylic acid on photosynthetic characteristics of strawberry under salt stress were studied.The results showed that exogenous hormones could ease salt stress induced injuries,increase net photosynthetic rate and transpiration rate,enhance stomatal conductance,decrease intercellular CO_(2)concentration,raise stomatal limitation,increase the chlorophyll content and strengthen the root vigour. |
