Test Allium cepa as indicator of genotoxical activity of the aveloz Euphorbia tirucalli

The objective was to identify the genotoxic activity of the aveloz, using the Allium cepa method, adapted methodologies applied in scientific literature. The experimental design was a completely randomized design with five treatments: five distinct concentrations of latex: 0; 0.15; 0.50; 0.75 and 1 mL L-1, with five replicates. After germination of the onion bulbs, slides were prepared with meristems and examined under an optical microscope. The applied treatments contributed to the presentation of two types of cellular aberrations: binucleate cells and bridges in anaphase and telophase. Further studies are needed to better assess the potential risks of the mutagenic agents present in hazelnut latex, as well as to adjust the methodology used.
