ABSTRACT: Uniform seedlings were treated with different concentrations of glyphosate for 24 hours. Then they were thoroughly washed with distilled water and kept for germination in petridishes containing double layered filter paper at room temperature for 72 hours. The effect of herbicide on liner growth of hypocotyl and radicle was noted. Glyphosate was effective in checking the linear growth of seedlings. This herbicide inhibited the linear growth of seedlings and caused swelling. The radicle was found to be more succeptible than hypocotyl. The lethal dose was found to be 600 ppm for hypocotyl and 500 ppm for radicle. The seedlings showed some morphological changes like inhibition of lateral roots formation and color of seedlings changed from green to yellowish observed due to application of glyphosate.
