| 摘 要： | 采用温室砂培盆栽试验研究了假繁缕(Pseudostellaria maximowicziana)对铅、锌积累的影响.结果表明,在所设定的重金属浓度范围内,假繁缕根干质量、地上部分干质量、根冠比及植株铅、锌含量均随所施铅、锌浓度的增加呈增大的趋势.根和地上部分铅含量最大值分别为1386.08,1197.93mg/kg;锌含量最大值分别为9250.50,8243.15mg/kg.植株铅和锌转运系数均1.偏相关分析表明,假繁缕根和地上部分铅、锌的吸收间可能产生协同或加和作用. |

| Abstract: | Effects of Pseudostellaria maximowicziana accumulating Pb and Zn were studied.Pot plant experiment was carried out in the sand growth incubator.Both the biomass of Pseudostellaria maximowicziana in the roots and the shoots and the ratio of root to shoot(W/W) had increased,also the Pb contents of Pseudostellaria maximowicziana and the Zn contents increased as well with increasing of concentrations of Pb and Zn in nutrient solution.The highest Pb contents in the roots and the shoots of Pseudostellaria maximow... |
| Keywords: | Pseudostellaria maximowicziana Pb Zn characteristics of accumulation |
