采用英国ADc公司生产的LCi便携式光合仪测定系统，对4个大棚栽培甜瓜品种的光合参数进行了研究比较。结果表明，供试品种的光合参数品种间差异显著，其中翠玉2号、豫金香的净光合速率（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，具有较大的高产潜力。

The LCi portable photosynthesis system was used to study the photosynthetic characteristics ol 4 melon varieties in Plastic House. The results showed that the diferences of photosynthetic parameters of diferent varieties were distinct. The net photosynthesis rate （ Pn ）, stomata1 conductance （ Gs ） and instantaneous carboxylation eficiency （ Pn/Ci ） of Cuiyu No.2 and Yujinxiang were higher than the others,while their intercellular CO2 concentration （ Ci ） were lower, So photosynthesis productivity of these varieties behaved better. And their photosynthesis eficiencies were better than that of the others. That is to say, their highyield potential was good.
