| 摘 要： | 采用温室盆栽实验,接种从垃圾填埋场土壤中筛选的淡紫拟青霉菌和绿色木霉菌,研究其对龙葵(Solanum nigrumL.)的生理活性和吸收重金属的影响。结果表明,菌株对龙葵生长有促进作用,可增强龙葵对Cd、Pb的吸收能力。单一Cd污染时,淡紫拟青霉菌能增强龙葵的抗氧化能力,促进Cd从植物地下部分向地上部分迁移;单一Pb污染时,绿色木霉菌能降低龙葵的抗氧化能力,不能明显促进Pb的迁移。在Cd、Pb复合污染时,两种真菌的混合液能较好地促进龙葵对重金属的吸收,龙葵对Cd的富集系数最高可达到4.25,而其对Pb的富集系数最高仅为0.19。 |
| 关 键 词： | 龙葵 重金属 微生物 生理活性 生物吸收 |

| Abstract: | Effects of Paecilomyces lilacinus and Hypocrea virens screened from soil in a landfill on physiological activity of Solanum nigrum and absorption of heavy metals were studied by pot experiment in greenhouse.The results showed that the strains could promote the growth of Solanum nigrum,and thus increase its absorption ability for Cd and Pb.Paecilomyces lilacinus could improve antioxidant capacity of Solanum nigrum,and promoted the migration of Cd from soil to the stem and leaf of Solanum nigrum when soil was... |
