Genotoxicity of Two Organophosphate Insecticides Based on Allium Test
The genotoxicity of two organophosphate insecticides, Folidol and Malathion, was each determined on root tip chromosomes of onion (Allium cepa L.). Acetocarmine squash preparations of roots grown from seeds untreated (control) and treated with two concentrations of Folidol (0%, 0.5% and 0.75%) and t...
