| 摘 要： | 采用水培试验研究了不同浓度的重金属Cd(15、30 mg·L-1)污染下,不同浓度Zn、Cu(10、40 mg·L-1)对香根草生长、丙二醛(MDA)含量、根系活力、可溶性蛋白质、叶绿素含量以及香根草体内Cd积累的影响.结果表明,除了低浓度的Cu外,不同浓度的Zn、Cu、Cd对香根草体内生理生化指标都产生协同或加和作用,提高了香根草体内MDA含量,降低了根系活力、叶绿素a、b含量以及可溶性蛋白质含量.Zn、Cu对植物吸收Cd的复合作用较为复杂,其中对香根草地上部Cd的转移可能产生拮抗作用,对根部Cd的吸收可能产生协同或加和作用.

| Abstract: | Hydroponic experiments were carried out to investigate the influence of different zinc(Zn) and copper(Cu) levels(10,40 mg.L-1)on the growth,malondialdehyde(MDA)content,root activity,soluble protein,contents of chlorophyll a and b,and accumulation of cadmium(Cd) in Vetiveria zizanioides L.when they exposed to different Cd(15,30 mg.L-1)levels.The results showed that except the low level Cu treament,the combination of Zn-Cd and Cu-Cd exhibited synergistic decreasing effects on root activity,chlorophyll,protein contents,whereas made the MDA increase in experiments.The effects of Zn and Cu on the plant assimilating Cd were complex.The combination of Zn-Cd or Cu-Cd on Cd accumulation in shoots may have antagonism effects,and on the absorbing of Cd in roots it may have synergistic or addition effects. |
