| 摘 要： | 研究了土壤中低含量铅(Pb)-苯并[a]芘(B[a]P)复合污染对小麦种子萌发率、根伸长、芽伸长以及芽根比的影响,以期考察复合污染的生态效应并筛选具有指示土壤污染程度的指标.结果表明,小麦种子萌发率对Pb-B[a]P单一及复合污染均不敏感;Pb和B[a]P单一污染时小麦根伸长均受到一定程度的抑制作用;复合污染条件下Pb...

| Abstract: | Seed germination,root elongation,shoot elongation and ratio of shoot to root of wheat in soils polluted by lead(Pb) and benzo(a)pyrene(B[a]P) with medium-low concentrations were studied to reveal the ecological effects of combined pollution and screen the indicative markers.Results indicated that seed germination was not sensitive to single or combined pollution of Pb or B[a]P.Root elongation was inhibited by single pollution of Pb or B[a]P to different extents.Extensive interactions between Pb and B[a]P oc... |
