Abstract:Initial growth effect and ecological threshold of F.arundinacea under progressive stress of heavy metal Cu 2+ and Zn 2+ were investigated. The results showed that under progressive stress of Cu 2+ and Zn 2+ , the growth of F.arundinacea was inhibited by different degrees in each treated concentration, and the inhibiting effect increased as increase of heavy metal concentration. The most significantly negative linear correlation was run between each index determined and stress concentration( C )...
