Abstract: With the method of inserting3H TdRinto DNA, this paper studied the inductive effect of Cd2+ and Al3+ on unscheduled DNA synthesis (UDS) and micronucleus (MCN) in Vicia faba, the correlation between UDS and MCN, and the feasibility of using higher plant UDStest as the indicator to detect environmental mutagens. The results indicated that both Cd2+ and Al3+ could induce UDS and MCN in Vicia faba. There was a negative relationship between UDS and MCN, but it was not significant. The relationship between UDS and MCN was similar under the treatments of Cd2+ and Al3+ respectively. It was reliable using higher plant UDS test as the indicator to detect environmental mutagens within certain dosage range.
