| 中文摘要 |
| 以盆栽法研究Cd对小白菜的伤害与La-Gly对Cd伤害小白菜的生态生理效应。结果表明,200mg/L CdCl2严重抑制小白菜代谢与生长,叶面施用100mg/L La-Gly 1次,能减轻Cd造成的伤害。实验证明,此与La-Gly能提高小白菜光合速率,希尔反应活力和硝酸还原酶活性,增加叶绿素及核酸含量,减少MDA与Cd含量,降低细胞质膜透性等多重作用相关。 |
| 英文摘要 |
| Ecophysiological effect of La Gly on Brassica chinensis under Cd stress was studied through pot culture experiment. The results showed that the growth and metabolism of Brassica chinensis are inhibited by 200mg/L CdCl2,while 10mg/L La-Cly is used to spray Brassica chinensis simultaneously,the injured effect of Brassica chinensis by Cd is reduced.The experiment proved this effect is related to that La-Gly raises photosynthetic rate, activities of Hill reaction and nitrate reductase,increases the contents of chlorophyll and nucleic acid,decreases the contents of Cd and malondialdehyde,reduces cell membrane premeability of Brassica chinensis. |
