Estimation of citogenetic effects on caffeine treatment in dill root meristems

3 Keywords: mitotic index, chromosome aberration, caffeine, Anethum graveolens L. Abstract: The analysis of some cytogenetic parameters shows that the caffeine application on Anethum graveolens L. species induced a light mutagen effect on the cells of the root apex. At the same time is an accumulation of cells with aberrations in ana-telophases, especially ana-telophase with lagging and expulsed chromosomes but also in metaphases (metaaphases with expulsed chromosomes, C-metaphases and picnotic chromosomes) demonstrating the perturbations of mitotic spindle function after treatment with caffeine.
