| 摘 要： | 采用盆栽实验法,研究不同浓度铬胁迫下扁穗牛鞭草(Hemarthria compressa)对Cr的吸收积累及生理特征.结果表明,在梯度实验中,植物体内的富集系数＞1.0,转移系数除对照组外都＜1.0.当铬处理浓度达80 mg/L时,根、茎和叶中铬的含量分别为1565.83 mg/kg、57.38 mg/kg和763.6...

| Abstract: | By using pot experiment,the accumulation and physiological characteristics of Hemarthria compressa at different concentrations of chromium were studied.Results showed that the values of bioaccumulation were more than 1.0 and the values of translocation were less than 1.0 except the control group in gradual experiment.Chromium contents in the roots,stems and leaves were 1 565.83 mg/kg,57.38 mg/kg and 763.68 mg/kg respectively when the chromium treatment concentration was up to 80 mg/L.The greatest amount of ... |
