通过不同程度的水分胁迫对欧李叶水势、气孔导度、蒸腾速率和光合速率日变化影响的研究。结果表明在水分胁迫下,欧李叶水势、气孔导度、蒸腾速率和光合速率降低,且随胁迫程度加剧而增大。水分胁迫使欧李光合速率日变化曲线由单峰型变成双峰型。
Effects of Different Degree Water Stress on Diurnal Changes of Water Potential, Stomatal Conductance, Transpiration and Photosynthesis of The results showed that under water stress, the leaf water potential, stomatal conductance, transpiration rate and photosynthetic rate decreased, and with the degree of stress increased. The diurnal variation curve of photosynthesis rate of European plumule changed from unimodal to bimodal with water stress.
