摘      要：The aim of this paper was to investigated the photosynthesis and peroxidases response to two watering regimes(well-watered and water-stress conditions) and to two nutrient regimes(with or without fertilization) of oil *** net photosynthesis rate(Pn) and transpiration rate(Tr)of different treatments with similar two-peak and single-peak changing tendency,*** treatments showed the lowest photosynthesis,transpiration rate when the comparatively higher air temperature light density and intercellular CO concentration at 12:00-13:***
