The present study was carried out to evaluate the herbicidal toxicity on seed germination, morphological and biochemical parameters of Triticum aestivum L. var HD-2189.Wheat grains were germinated with six different concentrations of butachlor (0.15, 0.25, 0.5, 0.75 and 1.0ppm) and the seedlings were maintained up to 15 days. Germination percentage, vigour index and tolerance index decreased significantly when compared to control. On the contrary phytotoxicity increased as the butachlor concentration increased. The length of the plumule and radicle decreased significantly as the concentration of the butachlor increased. Further the fresh weight decreased as the concentration of the butachlor increased, on the contrary the dry weight increased at the higher concentrations of the butachlor. The chlorophyll a, b, total chlorophyll and carotenoid content of 8th day seedling were decreased as the concentration of the herbicide increased. The protein content was found to be decreased in root-shoot axis; however it increased in endosperm as the concentration of the butachlor increased. The carbohydrate content increased both in root-shoot axis and endosperm as the concentration of the concentration of the butachlor increased.
