摘要/Abstract

摘要： 铜尾矿上的鹅观草形态矮小,茎秆柔弱,叶色淡.而生于正常土壤上的鹅观草则茎秆粗状,叶色深.Cu胁迫可引起鹅观草叶绿素含量的降低.一定浓度范围内的Cu对鹅观草的种子萌发起促进作用,尾矿浸提液不降低种子的萌发率,但延迟种子的萌发.根生长实验表明,0.125mg·L^-1Cu对鹅观草生根起促进作用,超过0.25mg·L^-1则抑制鹅观草的生根,生于正常土壤上的鹅观草比生于尾矿上的鹅观草对Cu敏感.

关键词: Cu, 鹅观草, 根生长, 种子萌发

Abstract: Roegneria kamoji grown copper tailings had weak stem,short height,and thick leave color,while its counterpart on normal soil was the opposite.Exposed to copper,R.kamoji had a decreased chlorophyll content.A certain concentration of copper could promote the seed germination of R.kamoji,and the extract of copper tailings did not decrease the seed germination rate,but deferred the germination.Root growth test indicated that when the concentration of copper was 0.125mg稬^-1,the rooting of R.kamoji was promoted.If the concentration was more than 0.25mg稬^-1,the rooting was inhibited significantly.R.kamoji colonized on normal soil wase more sensitive to copper than that on Cu polluted soil.

Key words: Copper, R.kamoji, Root growth, Seed germination
