| 摘 要： | 探讨不同浓度的Cd^2＋对不同品种旱稻发芽的影响，结果表明：低浓度镉（≤1mg／L），对旱稻种子的萌发有促进的作用。高浓度（≥10mg／L）会影响旱稻种子的发芽率（种子发芽率以70％计），且随Cd^2＋浓度增加，抑制作用增强。Cd^2＋对旱稻幼根生长的影响，在低浓度下即表现为抑制作用，根长随Cd^＋浓度的增加而递减。不同旱稻品种对镉的反映不同，0-119的耐镉性最强，2179—1次之，超级稻最差。

| Abstract: | concentrations of Cd~on different varieties of upland rice germination showed that： low concentrations of cadmium （~〈 1 mg＇L-1） played promoting role to the upland rice seed germination. High concentration （〉~ 10 rag＂ L-t） will affect the upland rice seed germination rate （seed germination rate of 70 percent）, and with The results of exploration on the different the Cd^2＋ concentration increased, enhanced inhibition. Cd^2＋ on the radicle growth of upland rice in low concentration that is manifested as a disincentive to root length with increasing Cd^2＋ concentrations decrease. Different upland rice varieties to reflect the different cadmium ,0-119 of the strongest resistance to cadmium ,2179-1 times, the worst super rice. |
