通过纸间发芽试验，探讨了不同浓度的镉（Cd2+）对荞麦种子发芽的影响.结果表明：低浓度的Cd2+溶液对荞麦种子发芽具有一定的促进作用.当Cd2+浓度为1.0 mg/L时，荞麦种子的发芽势显著高于对照；发芽率、根长和芽长指标均高于对照，差异达到了极显著水平；发芽指数显著高于对照；活力指数也高于对照，但差异未达到显著水平.随着Cd2+处理浓度的增加，发芽势、发芽率、根长、芽长、发芽指数和活力指数均呈下降趋势.

Through paper-germination test,the effects of Cd2+in different concentration on the germination of:Buck-wheat are studied. It shows that low concentration of Cd2 +solution of Buckwheat seed has certain simulative effect. When Cd2+concentration 1.0 mg/L, the seeds Buckwheat germinate was significantly higher than control group. Root and shoot length, and germination reached extremely significant difference between with control group. Germination index significantly higher than control group and comparison with high index of vigor. But the vigor index not signifi-cant differences. With the increase of the concentration of Cd2, germination rate, root, sprout, germination index and vigor index declined.
