ABSTRACT
Lens esculenta is an important cereal and rich in protein content. Several fungicides used are often considered a quick, easy and inexpensive solution for controlling fungus. One of them fungicide is fludioxonil, its cytotoxic effects on root tip meristem cells of Lens esculenta were investigated. For this aim, four different concentrations (0.1%, 0.2%, 0.3% and 0.4%) of fludioxonil were given at seed level for 24 hours. Aceto-orcein squash preparation of root tips of the treated seeds showed the chromosomal aberrations. All the dosages of the fungicide fludioxonil caused various abnormalities like univalents, multivalents, laggards, bridges, micronuclei, stickiness etc. in different stages of mitosis division when compared with control. Chromosomal aberrations were found to be correlated with the concentration of fungicides.
