Tolerance, Removal, Uptake and Accumulation of 2,4-Dichlorophenoland in Salix matsudana Clones

  • 摘要: 对4个旱柳(Sailx matsudana)无性系8,10,18和22号进行了水培试验,研究了96h后旱柳对水中2,4-二氯苯酚(2,4-DCP)的去除和吸收积累能力. 结果表明:旱柳可促进2,4-DCP降解,在96 h内4个旱柳无性系8,10,18和22号对20 mg/L的2,4-DCP去除率分别为56.63%,59.85%,55.17%和56.90%. 将4个旱柳无性系分别曝露在10,20和30 mg/L的2,4-DCP环境中,随着ρ(2,4-DCP)的增大,根系和地上部分中的w(2,4-DCP)增加,且根>茎叶;10号无性系地上部分未检测出2,4-DCP且其根系中的w(2,4-DCP)显著低于其他无性系;22号根系和地上部分的w(2,4-DCP)均显著高于其他无性系.水溶液中ρ(2,4-DCP)小于20 mg/L时,2,4-DCP对旱柳生长无显著抑制作用. 不同旱柳无性系对2,4-DCP均具有一定的吸收蓄积能力.
