| Popis: | In the present study, the cytogenetic effects of the herbicide Avenoxan on meiotic chromosomes of Allium cepa and its relation with pollen sterility were studied. The bulbs with roots of Allium cepa were treated with a series of concentrations (0.1%, 0.2%, 0.4%) for 3, 6, 12 and 24 h. Controls and treated plants were shown to obtain M1 generation. All the used concentrations of the herbicide Avenoxan and exposure periods caused distinct increase in the number of abnormal cells when compared with the control. The type of the abnormalities induced: chromosome stickiness, bridges, laggards, univalents, quadrivalents and micronuclei. Avenoxan also caused pollen sterility. Increase of chromosomal aberrations was accompained by increase in pollen sterility. |
