【 摘 要 】

Potting and continuous drought was applied to study the effect of drought stress (2 days for a treatment interval and 0-14 days of continuous drought) on the growth and photosynthetic characteristics of Sophora japonica L. saplings. The results were received as followed. (1) The ground diameter and height increment of Sophora japonica L. saplings were inhibited under drought stress. There was no significant difference under mild and moderate drought treatments (drought time 2-8 days) compared with the control group in leaf water content and leaf relative water content; and serious drought treatment (drought time > 10 days) was significantly lower than that of control group (P
