Effects of Combined Pollution of Lead and Benzo[a]pyrene on Seed Growth of Wheat in Soils
土壤铅-苯并[a]芘复合污染对小麦种子生长的影响研究

Seed germination,root elongation,shoot elongation and ratio of shoot to root of wheat in soils polluted by lead(Pb) and benzo(a)pyrene(Ba]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 Ba]P.Root elongation was inhibited by single pollution of Pb or Ba]P to different extents.Extensive interactions between Pb and Ba]P oc...
