| Abstract: | Willows have been shown to be promising for heavy metal phytoextraction.However,the characteristics of migration and distribution of copper in salix matsudana Koidz are still not clearly known.In order to better identify these characteristics,based on hydroponic experiment,the concentrations of Cu in different tissues of Salix matsudana Koidz were measured using ICP-AES,and the microscopic structures of Cu in different tissues were investigated using SEM-EDAX.The results showed that Cu concentrations in roo... |
