摘　　要：研究了基因型不同的10个番茄品系幼苗功能叶片在不同弱光胁迫处理后,光合速率、蒸腾速率、气孔导度和胞间CO2浓度的变化。结果表明,各番茄品系的光合速率、蒸腾速率均随光强的减弱逐渐降低,而气孔导度和胞间CO2浓度在不同光环境下呈现出不同的变化趋势。The photosynthetic rate, transpiration rate, stomata conductance and internal CO2 concentration in function leaf at seedling stage of 10 tomato varieties were investigated under the treatments of different low light density. The result showed that photosynthetic rate and transpiration rate were gradually decreased with the reducement of light density and the change tendency of stomata conductance and internal CO2 concentration were different among the tested varieties under different low light density.
