Genotoxic Effects of Two Pesticides (Rogor and Bavistin) and an Antibiotic (Streptomycin) in Meiotic Cells of Grasspea (Lathyrus sativus L.)

Abstract

The cytological effects on the pollen mother cells of Lathyrus sativus grown after seed treatment with different concentrations of two pesticides (rogor and bavistin) and an antibiotic (streptomycin) indicated that all the three chemicals were capable of inducing cytological disturbances. The dominant types of aberrations included: stickiness, univalents and multivalents, laggards, fragments and bridges. Besides these, some cases of cytomixis were also recorded. Streptomycin proved to be more efficaceous followed by rogor and bavistin. Thus, the genotoxic effect of these chemicals is established.
