Evaluation of Genotoxicity of 4-n-Nonylphenol using Vicia faba L.
F.I.M. Adam and Z.M. El-Ashry

The present investigation dealt with the effects of 4-n-nonylphenol (NP) on the mitotic and meiotic division of Vicia faba L. Root-tips of Vicia faba was treated with a series of NP concentrations ranging from 25, 50 and 100 ppm for 3 and 6 h. The 4-n-nonylphenol (NP) concentrations used, generally had a marked metodepressive effect on Mitotic Index (MI) after all concentrations at 3 and 6 h except 25 ppm for 3 h. Spraying of Vicia faba flower buds with 25, 50, and 100 ppm of NP for 1, 2, 3 and 4 successive days were capable to induce positive results of abnormal Pollen Mother Cells (PMCs.). The 4-n-nonylphenol (100 ppm) caused killing 40% of flower buds. Several types of abnormalities were observed after all treatments in both mitotic and meiotic divisions. These types of abnormalities were: chromosome stickiness, disturbed chromosomes, ana-telophases bridges and lagging chromosomes. The 4-n-nonylphenol was induced change in esterase isoenzyme.
