Morphoanatomical and Structural Alterations in Psoralea corylifolia (L.) Induced by Glyphosate

The present study deals with the effect of glyphosate on the morpho-anatomical structures of Psoralea corylifolia seedling growing in cultivated fields of Vidarbha regions of Maharashtra State. The seeds were treated with different concentrations (100, 200, 400, 600 and 800 ppm) of the herbicide glyphosate. There was a gradual decrease in growth of radicle and hypocotyl with an increase in concentrations of glyphosate. The length of radicle at control and 100 ppm was 18.2 mm and 9.6 mm, respectively. The decrease in length of hypocotyl at 100 ppm was 16.2 mm as against 32.4 mm in control, respectively. In the present study inhibition of lateral roots and change in colour of cotyledons from green to creamy white was observed in early seedling growth. It also induced some remarkable anatomical changes in the hypocotyl, radicle and cotyledon of Psoralea corylifolia seedling.
