Absorption, Accumulation and Physiological Responses to the Phenanthrene Treatments by Perennial Ryegrass (Lolium perenne L.) [PDF]
, 2008 多环芳烃污染是近年来受到广泛关注的一个环境问题，但是由于相关研究开展较晚，目前对于多环芳烃污染的植物修复、农产品安全等方面的机理研究仍不充分。 本文以多年生黑麦草（LoliumperenneL.）为研究对象，以菲为多环芳烃的代表，采用溶液培养的手段，探讨了植物对多环芳烃的吸收、积累和体内运输以及植物生长、根系分泌、体内解毒酶的响应，研究结果如下： （1）黑麦草对菲的吸收、积累、运输：黑麦草能够从溶液中吸收菲，并且能够将根系吸收的菲向地上部分运输；黑麦草根系和地上部分吸收菲的浓度与溶液中菲的浓度有关 ...
