Abstract:

In our research, the effect of the DICOPUR D pesticide on the germination of wheat seeds, plant growth, as well as on cell division in root meristems was studied. The results have shown that the pesticide used inhibits germination even at low concentrations of the test solution; plant growth and development is also negatively influenced, and in terms of cell division, the mitotic index is much lower compared to the control variant. The percentage of cells with chromosomal aberrations was higher for samples tested with DICOPUR solutions. The 1.5 concentration of the DICOPUR solution resulted in total inhibition of the germination process of the wheat seeds.

Keywords:

Triticum aestivum, DICOPUR D pesticide, biometric measurements, cell division, the mitotic index, chromosomal aberrations.
