EFFECTS OF GLYPHOSATE ON VIGNA RADIATA VAR. ML613 ASSESSED BY MEIOTIC BEHAVIOUR, TOTAL PROTEIN AND GST ACTIVITY
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
Dose related variation in morphological and yield parameters was observed in Vigna radiata var. ML613 after glyphosate treatment in the first year of sowing. The best performing plant (most vigorous) was selected from the entire population at each dose and its seeds were sown to raise their respective families in the second generation. Post emergence treatment of the same, one lower and one higher dose of glyphosate was given in triplicate to the plants of each family 21 days after sowing. Meiotic studies were done when buds were of appropriate size. Meiotic study of recurrent glyphosate treated Vigna radiata showed micronuclei induction along with chromosomal aberrations. The number of micronuclei decreased with increase in glyphosate concentration while the relative abnormality rate increased with increase in glyphosate concentration. Both these cytological parameters are indicators of mutagenic potential, which was established for glyphosate in our study, and can have long term effect on the qualitative/ nutritive value of the crop plant. Total protein also decreased in the treatments while GST activity increased under the effect of herbicide treatment. A possible interdependence between the oxidative stresses imposed by the herbicide glyphosate in Vigna radiata ML613 has emerged from the above study and the role of antioxidative enzymes like glutathione-S-transferase in ameliorating cytotoxicity is hypothesized.
