... Plants are valuable genetic assay systems for screening and monitoring environmental pollutants (Singh et al., 2008), they constituting indicators of cytotoxic, cytogenetic, and mutagen effects of chemical polluters by the detection of lesions induced at genetic level by the respective compounds. Trigonella foenum graecum L. (Fabaceae) can represent a monitoring system in the evaluation of possible genetic risk of carbendazim and other pesticides, because it is a species of great pharmaceutical, industrial, and culinary interest and its chromosome complement has a relatively reduced number of chromosomes of large sizes (Căpraru et al., 2006). The trigonelline alkaloid has shown potential for use in cancer therapy (http://www.pfaf.org/database/plants.php?Trigonella+f oenum-graecum). ...
Because the studies on pesticide effects evidenced a diversity of chromosomal aberrations, in relation to the analysed class of compounds, we considered necessary to test the influence of carbendazim fungicide on genetic material of fenugreek (Trigonella foenum graecum L.), which can constitute, as other plant species, monitoring systems in the evaluation of possible genetic risk of the pesticide use. Mitotic index, the frequency of cell division phases, the types and incidence of ana-telophase aberrations, and the types of metaphase abnormalities were studied. The mitotic index was lower in all carbendazim treated variants; the most numerous ana-telophase aberrations and metaphase abnormalities were noted in 0.5% and 1.0% carbendazim treated variants. The effect of carbendazim on height growth of plantlets in early ontogenetic phases was also investigated – an inverse relation between concentration and plantlets’ height was registered.
