　　Photosynthesis is one of the most sensitive physiological processes to water deficits.Here, cucumber (Cucumis sativus L.) seedlings with 6-7 leaves were deprived of water to study photosynthetic responses to water stress.The results showed that, a decrease in stomatal conductance occurred early in response to water deficit and may prevent excessive.dehydration and improve water use efficiency in cucumber plants.
