Abstract

It is serious for Cd contamination in environment in currently，there is large potential of phytoremediation of Cd contamination. For provide excellent phytoremediation material，this study focused on willow Cd tolerant heritability，ability of Cd colerance，and changes in leaf physiological characteristics with Cd stress by hydroponics. Ten clones （No.2，No.3，No.4，No.5，No.8，No.9，No.10，No.13，No.16，and No.18） of Salix matsudana were used as the experimental material. Results indicated that when Cd concentration was 30 － 60 mg·L-1，the content，mass，and amount of accumulation in aboveground organs，the mass and amount of accumulation in roots，and chlorophyll all had stronger heritability. For the 10 clones，Cd tolerance was in the order of：No.13＞No.8＞No.16 ≈ No.18 ≈ No.9＞No.2＞No.4＞No.10＞No.3＞5. Leaf physiology changes with Cd stress indicated that chlorophyll and dissolubility protein contents as well as conductance decreased，malondialdehyde（MDA） increased，and proline change followed no pattern.［Ch，4 tab. 20 ref.］
