灌木型柳树镉吸收积累性状的研究
Cadmium Absorption Characters of Bush Willow
摘要
Abstract
Cadmium contents in the leaves and twigs of 131 clones of bush willow cultured in nutrient solution with a cadmium concentration of 5.0× 10-6 were measured. Cadmium contents ranged from 39.68×10-6 to 162.40× 10-6 in twigs of tested clones, while from 53.55× 10-6 to 298.43× 10-6 in leaves. No significant differences were found among 11 major hybrids in cadmium contents in leaves or twigs; there were different correlations between cadmium contents in leaves and those in twigs for each hybrid; cadmium contents in leaves were higher than those in twigs for 90 ％ of tested clones. These results suggested that selections of new willow varieties could be got available through directly testing clones for higher cadmium contents in twigs or leaves.关键词
