摘　　要：对露地栽培的18个葡萄品种自然环境下的光合参数进行了研究比较。结果表明,参试品种的光合参数品种间差异显著,其中金星无核、力扎马特、红提和京秀的净光合速率(Pn)、气孔导度(Gs)和叶肉瞬时羧化效率(Pn/Ci)都较高,胞间CO2浓度(Ci)较低,表现了较好的光合能力,其光合效率明显高于泰安地区主栽品种巨峰,且具有较大的高产潜力。Photosynthetic parameters of 18 grape varieties which cultured in open-field were compared. The results showed that the differences of photosynthetic parameters of different varieties were distinct. The net photosynthesis rate （Pn）, stomatal conductance （Gs） and instantaneous carboxylation efficiency （Pn/Ci） of Venus, Pизамат, Red grape and Jingxiu were higher than the others, while their intercellular CO2 concentration （Ci） were lower, so photosynthesis productivity of these varieties behaved better. And their photosynthesis efficiencies were better than that of Jufeng, the primary cultured variety at present in Tai＇an. That is to say, these varieties were seasoned with the natural environment of Tai＇an better and their high yield potential is good.
