【 摘 要 】

The present study evaluates the antigenotoxic effects ofB. juncea (L.) Czern.(Indian mustard) aqueous seed extract on theAllium cepaL. (common onion) root tip cells. The experiment was carried at three stages: (1) onion bulbs were treated with 0.75 ppm mercury for 3 h, and then treated with different concentrations (0.1, 0.25, 0.50, 0.75, and 1.0%) of aqueous extract for another 3 h. (2) onion bulbs were treated with different concentrations of extract for 3 h, and then treated with 0.75 ppm concentration of mercury. (3) Onion bulbs were treated with different concentrations of extract and 0.75 ppm concentration of mercury simultaneously for 3 h. Increase in root growth and mitotic index and decrease in chromosomal aberrations were observed in root tip cells treated with aqueous extract of seeds, after before and simultaneously with mercury treatment as compared to control. The dose dependent effects suggest that aqueous extract of Indian mustard has antigenotoxic potential against mercury induced genotoxicity.
