Description

Root tips of Allum cepa were treated with solutions containing 1000, 100, 10, 1 and 0, 1μg/ml of the mycotoxins patulin, rubratoxin B and diacetoxyscirpenol. The most striking damage was reduction of the mitotic index and metaphase arrest by all toxins and chromosomal aberrations, appearance of nuclei with two nucleoli as well as vacuolization of the cytoplasm under the influence especially of diacetoxyscirpenol which proved to be the most active toxin.
