Effect of agrochemical (2,4-D) on anatomical aspects of Cassia tora Linn.

摘要

Present investigation carried out in the botanical garden and research laboratory of the college. The herbicidal activities of agrochemical (2,4-D) on Cassia tora Linn. have been studied. The anatomical response might produce some light on the manner by which this compound affected on plants. The plants were sprayed with aqueous solution of different concentrations of herbicide from 50 to 1000 ppm. 2,4-D induced some anatomical changes like proliferation of cambium and phloem in the stem and root to form large masses of meristematic cells, due to the proliferation of cortical and pith cells after treatment become ruptured. In the leaves, desiccation of cells, proliferation of cambium in the midrib region, distortion of vascular elements and disorganization of mesophyll cells was common feature observed after 2,4-D treatment.
