The cytogenetic effects induced by two caffeine concentrations (0.1%, 0.5%) in root meristematic cells of plants belonging to two species of economic importance Phaseolus vulgaris and Raphanus sativus are described in this article. Mitotic index, frequency and type of ana-telophase chromosome aberrations, as well as frequency and categories of metaphase abnormalities were comparatively analyzed for the two species. The results showed that caffeine has genotoxic potential; it induces important alterations at the level of genetic material. The maximum tested concentration (0.5% caffeine) provided the most complex pattern of ana-telophase aberrations, especially in radish R. sativus genotypes presented a higher sensibility to the caffeine action.
