| 摘 要： | 测定了杜松、新疆杨的水势,研究了它与树木光合作用、蒸腾作用的关系及其对树木正常生命活动的意义,结果表明:杜松、新疆杨小枝不同水分状况下的相对总光合速率随水势绝对值的增加而呈下降趋势.蒸腾速率则随着水势绝对值的降低而下降,其下降速率是由慢到快再到慢.

| Abstract: | The relationship between photosynthetic rate,transpiration rate and the leaf water potential of Juniperus rigida Sieb.et Zucc.and Populus alba var.pyramidalis Buge P.bolleana Lauche] were studied.The results showed that the photosynthetic rate and the leaf water potential on Sieb.et Zucc.and the relative total photosynthetic rate defined,and the transpiration rate was maximum when the trees were water saturated state.With the leaf water potential absolute value slowed,transpiration rate was reduced. |
