文摘内容 Water stress can cause all kinds of physiological and biochemical responses on forest tree, which are indicated by changes of many physiological and biochemical indexes. Under the different drought extent of soil, the seedlings of Rob-inia pseudoacacia clones were tested. Testing indexes included water content, the ratio of bound water content and free wa-ter content ( Vα/Vs), free proline, soluble sugar, soluble protein ect. The results showed that water content decreased with the increase of soil drought, the rest indexes increased in different extent. The range of variance differed among clones. It was difficult to evaluate exactly the drought resistance of different clones depending on only physiological and biochemical index。
