MATERIALS AND METHODS: The root tips of Vicia faba were treated with different concentrations of sodium sulfite and sodium nitrite (in the concentrations of 25;50;100;200;400 mg/L) with distilled water as control for four hours.The root tips of Vicia faba were stained with carbol fuchsin and examined. The micronucleus rate and the rate of chromosome aberration were determined within root tip cells of Vicia faba.
