采用室内生物测定方法,选用预实验筛选所得的10mg.L-1的镉胁迫对宁波市常见的12个小白菜品种进行萌发实验,通过测定发芽率、发芽指数、活力指数、胚芽长、胚根长、鲜重和干重等指标,同时结合模糊数学隶属函数法对小白菜的耐镉性进行了综合评价.结果表明：不同小白菜品种间种子萌发受镉胁迫的抑制程度存在明显差异,在供试的12个品种中,青种黄芽菜的耐镉性较强,而菊锦、耐热小将等耐镉性较差.

Using the techniques of laboratory bioassay,10 mg.L-1 Cd solution is used to stress the cabbage seeds of 12 kinds mainly cultivated in Ningbo city.By measuring the following parameters： germination rate,germination index,vigor index,root and shoot height,fresh and dry weight,the cadmium-resistant ability of cabbage is assessed using membership function.The results show that there are significant differences in seed germination among different cabbage cultivars.Among all tested 12 cultivars,the Qingzhonghuangyacai has the strongest resistance to Cd,while the Jujing and Nairexiaojiang are found weak in this respect.
