Characteristics of Heavy Metals Tolerance and Growth in Two Ecotypes of Oxyria Sinensis Hemsl.Grown on Huice Lead-Zinc Mining Area in Yunnan, China
A field survey of herbaceous growing on Huice lead-zinc mining area in Yunnan,China was conducted to identify species accumulating concentrations of Cd,Pb and Zn in plants.In total,200 plant samples of 112 species of 34 families were collected.In the same time,200 soil samples were collected.According to characteristics of tolerance to Cd,Pb and Zn and growth,wild Oxyria sinensis Hemsl.were chosen as a primary pioneer plant.Then,to confirm if Oxyria sinensis Hemsl.can be use as a pioneer plant,the characteristics of tolerance to Cd,Pb and Zn and growth of two ecotypes (mining area ecotype and non-mining area ecotype) Oxyria sinensis Hemsl.were studied further with treatment of Cd,Pb and Zn in pot experiments.In 10 samples of wild Oxyria sinensis Hemsl.
