摘要
修复植物筛选是植物修复研究的重要组成部分。试验以5种植物种子为研究对象,观察其在不同石油污染模拟浓度下,种子发芽率和幼苗早期生长状况对污染的响应。结果表明:紫花苜蓿和蛇目菊受污染抑制程度较小,表现出作为修复植物的潜力。
Screening plants is an important part for phytoremediation research of petroleum contaminated soils. In this research, seeds of five species were selected. Responses of seed germination and early growth to different levels of petroleum pollutants were observed. The results showed that there was less restrictions on growth of Medicago sativa and Coreopsis tinctoria by petroleum pollutants. They displayed the potential of remedying petroleum contaminated soils.
