| 摘 要： | 目的]为花卉植物用于cd污染土壤栽培提供依据。方法]采用水培试验研究了镧（工丑）对羽衣甘蓝受到镉（Cd）胁迫的调节效应。结果]低浓度的cd对羽衣甘蓝的出芽率、株高、根系、地上和地下鲜重与千重等指标均有一定的抑制作用，高浓度的cd对其有明显的抑制作用，而一定浓度的La可以缓解这种抑制作用。结论]5mg／LLa缓解高浓度cd对羽衣甘蓝种子出芽以及生长等各项指标的抑制作用效果最好。

| Abstract: | Objective] To provide basis for planting flowers in Cd contaminated soil. Method] The hydroponic method was adopted to study the regulating effect of La on the growth of Brassica oleracea var. acephala under Cd stress. Result] The seed germination rate, plant height, root growth, aboveground and underground fresh weight and dry weight of Brassica oleracea var. acephala were inhibited under low concentration of Cd, while significantly inhibited under high concentration of Cd, certain concentration of La c... |
