Abstrakt		Onion (Allium cepa L.) bulbs were subjected to gamma irradiation with subsequent cytogenetic analysis over prolonged growth periods under field conditions. In root tip meristematic cells, micronuclei and types of chromosomal aberrations were observed and the mitotic index determined. The micronucleus test results in concordance with the chromosome aberration assay results indicated the extent of clastogenic effects of irradiation on plant genetic material. However, the best cytogenetic indicator for radiation hazard assessment was the complete mitotic blockade in root meristems.
