| 摘 要： | 利用LI-1600稳态气孔计测定了蚕豆叶片蒸腾速率的日变化以及水分胁迫下蒸腾速率的变化，探讨了环境因子对蚕豆叶片蒸腾速率的影响。结果表明，光量子通量密度是影响蒸腾速率的主要气象因子，土壤含水量影响叶片的相对含水量，并通过气孔扩散阻力来影响蒸腾速率。

| Abstract: | By using LI 1600 steady state porometer,the transpiration changes of the vicia faba L. leaves were determined through a day and under the condition of the water stress,in order to evaluate the effect of environmental factors on the transpiration rate of the V. faba leaves. The result indicated that the PFD is a principal meteorological factor influencing transpiration. The soil water content influenced the leaf water content, and the leaf water content influenced the transpiration by stoma diffusing resistance. |

| Keywords: | vicia faba L water stress transpiration rate stoma diffusing resistance factorial analysis |
