Chromosome damage induced by R7372 was investigated in Nigella damascena seeds (doses ranging from 31 to 155 × 10-5 M) and root tips (doses ranging from 0.97 to 15.6 × 10-5 M). Chromosome damage consisted in fragments, microfragments and gaps. There was also a chromosome uncoiling effects of R7372 and a synergistic effects with colchicine for metaphase accumulation. A linear relationship between dose and total effect was established for both seeds and root tips. The damage and the sensitivity of various phases of the mitotic cycle could be compared with the effect of another nitronaphtofuran (R7000).
