Volume : II, Issue : XI, December - 2012 MUTAGEN INDUCED CYTOTOXICITY IN TRIGONELL FOENUM-GRAECUM L. RUMANA ASLAM , SANA CHOUDHARY , A. H. KHAN , ALKA AND TOWSEEF MOHSIN BHAT Published By : Laxmi Book Publication Abstract : Present experiment was design to investigate the effect of methyl methane
sulphonate and sodium azide on Trigonella foenum-graecum L. treated with different
concentrations (0.01, 0.02, 0.03, 0.04, and 0.05%). The results indicate that there was a
direct correlation between increasing concentrations of mutagens and parameters
studied. Although meiotic abnormalities, pollen fertility and chiasma frequency showed
continuous decreasing trend with the increasing concentrations of both the mutagens but
the maximum decline was observed at the higher concentration (0.05%) of MMS and lest
was at lowest concentration (0.01%) of SA. However, MMS was found to be more
effective in inducing meiotic abnormalities, reduction in chiasma frequency and
decrease in pollen fertility as compared to SA. Further, a negative relationship between
increasing concentrations of mutagen and reduction in chiasma frequency in treated
population was also observed. Keywords : Article : Cite This Article : RUMANA ASLAM , SANA CHOUDHARY , A. H. KHAN , ALKA AND TOWSEEF MOHSIN BHAT, (2012).
