Chromosomenaberrationen in den Wurzelspitzen vonAllium cepa durch Aflatoxin B1

  • J. Reiss
Specialia Genetica

Summary

After treatment of roots ofAllium cepa with aflatoxin B1 in 0.3% dimethylformamide, chromosome bridges, C-mitose chromosomes and a reduction of the mitotic index were observed. The aberrations occurred especially frequently when the roots had grown in 200 µg/ml toxin for 48 h. In its cytotoxic effect onAllium cepa root tips, aflatoxin B1 acts similarly to the chemically related coumarin.
