Cytogenetic activities of fusarium spp. metabolites on A. cepa

Abstract

The effect of four mycotoxins on the chromosomal arrangement during mitotic cell division of Allium cepa was examined. Results indicate the presence of certain changes in mitotic stages index (M.S.I) as well as some chromosomal anomalies which reflect toxic activity due to the exposure of the tested bulbs to the four fungal species. F. equiseti gave the highest deviation of chromosomal index from the normal chromosome behaviour followed by F. solani, F. moniliforum and F. culmorum.
