| 摘 要： | 采用培养皿中的种子暴露试验方法,研究了2种城市绿化草种——多年生黑麦草和三叶草在不同多环芳烃菲污染浓度梯度和不同土壤改良方式下的种子萌发及其幼苗生长反应。结果表明:不同浓度菲污染对2个草种的发芽率和幼苗生长没有显著差异;除了低浓度胁迫下黑麦草处理外,所有处理的萌发指标大都随着菲胁迫浓度的提高而降低。此外,污染土壤的几种改良方式在一定程度上对草种的萌发及其幼苗生长有积极的作用。总的来说,表面活性剂和树木凋落物复合的改良作用效果要好于二者单独使用的效果。 |

| Abstract: | An exposure experiment of seeds in Petri dishes was conducted to study the responses of Lolium perenne and Trifolium repens seed germination and seedling growth to different concentration phenanthrene and different soil ameliorants.No significant differences were observed in the germination percentage and seedling growth among the two plants under different concentration phenanthrene,but the indices became worsened with increasing phenanthrene concentration.Several approaches for ameliorating contaminated s... |
