摘要：
The induction of sister chromatid exchanges (SCE) by chloride and nitrate salts of nickel, cobalt, cadmium and zinc were studied in meristematic root cells of Vicia faba. Salts of nickel, cobalt and cadmium significantly increased the frequency of SCE, whereas chloride and nitrate salts of zinc did not increase the frequency of SCE significantly above the spontaneous level. The reported data demonstrate that the induction of SCE in Vicia faba may represent a valuable bioindicator for detecting the cytogenetic damage of heavy metals.
