| 摘 要： | 采用培养皿种子发芽试验,研究不同浓度的Cr6 对小白菜种子萌发和生长的影响。结果表明,Cr在低浓度时(4￣5mg.L-1)对萌发有促进作用,达到一定浓度后(>8mg.L-1)即产生明显的抑制效应。Cr对种子萌发的的简化活力指数和下胚轴长度影响最大,此二项参数可作为Cr的毒性指标。

| Abstract: | The effects of Cr6 on Chinese cabbage seeds germination and growth were studied.Results showed that low chromium content can increase germination but decrease in more contents.The simplified vigor index of seeds germination and the length of hypocotyls are sensitive to the chromium concentrations,so both items may regard as the index of chromium toxicity. |
