GENOTOXIC EFFECTS OF COAL FLY ASH IN TRIGONELLA FOENUM GRAECUM (L.)

摘要

The aim of this research is to study the effects of different concentration (20%, 50%, 80%, and 100%) of Fly Ash with Vermicompost and Pressmud on the root meristems of Trigonella foenum graecum. 10 seeds were grown in pot at 20%, 50%, 80% and 100% concentration of FlyAsh. It was determined that FlyAsh increased the rate of the mitotic division at different concentration with the increase in mitotic anomalies. Very rare anomalies were encountered in the control group and at the concentration of 20% but at concentration of 50%, 80% and 100% of FlyAsh chromosomal aberration such as sticky metaphase, laggard chromosome, bridge chromosome, vagrant chromosome etc. were observed. Mitotic index increases from control to lower concentration of Fly Ash, while at higher concentration mitotic index gets lower and chromosomal aberrations get higher. At higher concentration frequency of chromosomal bridge were very high while at lower concentration sticky metaphase normally appeared.
