Abstract
A pot cultivation experiment was carried out to study eco-toxicological response of B.campestris L.var.purpurea Baileysh to copper.The results showed that low concentration copper in soil promoted B. campestris L.var.purpurea Baileysh growth: heighten the seedling, increased the biomass and content of chlorophyll, enhanced the activities of POD and SOD.B. campestris L.var.purpurea Baileysh grown in high concentration copper in soil were poisoned as follows:the seedling dwarfed,the green leaves turned yellow,the bloom postponed,the content of chlorophyll declined ,the activities of POD and SOD restrained.In addition ,the content of mineral nutrient in seedling dropped,which further deepened the toxicity of copper to the seedling.When the concentration copper in soil reached500?mg/kg,most of the seedling died.
