摘要
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。
This paper was carried out to study the effect of water stress on the diurnal change of photosynthetic rate of Chinese dwarf cherry. The result showed: under water stress, all the leaf water potential, stomatal, conductance, transpiration rate and the photosynthetic rate became lower than Ck's. And the degree of them was getting strong along with water stress' intensity.$$$$
