| 摘 要： | 以菜心种子和3种不同土壤介质（灰黄泥土、灰泥土、黄壤）为材料，研究重金属Cu、Zn、Pb和Ni单一污染和复合污染对菜心种子发芽率、芽长与根伸长的生态毒性效应。结果表明，同一浓度下，菜心种子发芽率、芽长和根伸长对重金属的生态毒性敏感程度依次为：根伸长〉芽长〉发芽率；重金属对菜心根伸长的生态毒性大小顺序为：Ni〉Cu〉Zn〉Pb；土壤中有机质和养分含量对菜心根伸长的抑制率呈显著负相关，土壤pH对菜心根伸长的抑制率相关性不显著。Cu、Zn、Pb、Ni复合污染对菜心根伸长的抑制效应表现为协同作用，其结果是复合污染的整体生态毒性效应增强。 |
| 关 键 词： | 土壤 菜心 重金属污染 生态毒性 复合污染 |

| Abstract: | With Brassica parachinensis seed and three different kinds of soils mediums(grey-yellow soils,grey soils,yellow soils) as the materials to research the eco-toxicity effects of single pollution and combined pollution of Cu,Zn,Pb and Ni on seed germination rate,shoot elongation and root elongation.Results indicated that with same concentration,the eco-toxicity sensibility orders of heavy metals on seed germination rate,shoot elongation and root elongation was root elongation>shoot elongation>germinating rate.... |
| Keywords: | soil Brassica parachinensis heavy metal pollution eco-toxicity combined pollution |
