Effects of harvesting on As accumulation and removal efficiency of As by Chinese brake (Pteris vittata L.)
刈割对蜈蚣草的砷吸收和植物修复效率的影响

Arsenic (As) contamination of soils is a major environmental problem both in China and in the world. Chinese brake (Pteris vittata L.), which has a strong ability to tolerate and hyperaccumulate As, is a good candidate for phytoremediation of arsenic-contaminated soils. To understand the processes of As hyperaccumulation by P. vittata and to take P. vittata into practice, a growing body of researches has been carried out on understanding the mechanisms of As tolerance and hyperaccumulation, including the As...
