以上海青为材料,研究重金属铜和铅对植物种子萌发率及幼苗鲜重和过氧化氢酶活力的影响.结果表明:重金属对植物的萌发率表现为低浓度时促进,高浓度时抑制;上海青对铜的最适浓度为1.5×10~(-5)mol/L,对铅的最适浓度为2×10~(-2)mol/L.同时,过氧化氢酶活力与重金属的浓度也呈现负相关.
以上海青為材料,研究重金屬銅和鉛對植物種子萌髮率及幼苗鮮重和過氧化氫酶活力的影響.結果錶明:重金屬對植物的萌髮率錶現為低濃度時促進,高濃度時抑製;上海青對銅的最適濃度為1.5×10~(-5)mol/L,對鉛的最適濃度為2×10~(-2)mol/L.同時,過氧化氫酶活力與重金屬的濃度也呈現負相關.

With Brassica rapa L as the materials to research the effect of Cu and Pb on seed germination and seedling physiology and biochemistry and the activity of CAT. The result showed that low concentration heavy metals could promote Brassica rapa L. seed germination, but high concentration showed inhibition. And the op timum copper concentration was 1.5×10~(-5)mol/L,lead concentration was 2×10~(-2)mol/L. At the same time, the activity of catalase(CAT) correlated negatively with heavy metals concentration.
