【目的】探究滴灌水分亏缺对南方季节性干旱区猕猴桃生育前期光合特性的调控效应，为南方季节性干旱区猕猴桃节水高产种植提供理论依据。【方法】以9 a生“金艳”猕猴桃为研究试材，以充分灌溉为对照（CK），分别在抽梢展叶期（I）、开花坐果期（II）设置轻度、中度、偏重度及重度4种亏缺水平（记为LD、MD2、MD1及SD，灌水量分别为CK的85%、75%、65%、55%），分析了滴灌水分亏缺对猕猴桃生育前期叶片光合特性的影响。【结果】水分亏缺显著降低猕猴桃生育前期叶片净光合速率（Pn）、蒸腾速率（Tr）和气孔导度（gs），且降幅均随亏水度加重而增大，但Pn降幅小于Tr和gs；与CK相比，I-MD1处理和II-MD2处理的Pn分别降低16.3%和6.5%，但叶片瞬时水分利用效率（WUEi）、叶片内在水分利...
