SISTER CHROMATID EXCHANGES INDUCED BY THINNER IN Vicia faba

摘要

Root meristem cells of Vicia faba were used as the test system for the detection of sister chromatid exchanges (SCEs) through the fluorescence Plus Giemsa technique. The results indicate that thinner composed of: 52.0% toluene, 25.5% n-hexane, 12.5% ethanol, 6.0% ethly acetate, 2.0% isopropanol, 1.Wo benzene and 1.0% n-heptante applied at concentration of 0.003, 0.006, and 0.012% induced a positive response in the frequency of SCEs.
