Abstract
The effect of herbicides on macromolecular seedlings was studied at the concentrations form 10 to 100 ppm of 2,4-D and 100 to 40,000 ppm of glyphosate and stomp. The protein contents of seedlings decreased gradually with the increased concentration of herbicides. The protein content of control seedlings was observed 2.10 × 10-4. In 2,4-D treated seedlings protein contents were 1.60 × 10-4, 1.58 × 10-4, 1.46 × 10-4, 1.31 × 10-4, 1.18 × 10-4 and 1.60 × 10-4 at 10, 20, 40, 60, 80 and 100 ppm, respectively. Glyphosate treated seedlings, the percentage of protein content per seedlings at 100, 1000, 5000, 10,000, 20,000 and 40,000 ppm were 1.95 × 10-4, 1.90 × 10-4, 1.83 × 10-4, 1.75 × 10-4, 1.50 × 10-4 and 1.20 × 10-4 , respectively. Following stomp treatment proteins content per seedling at 100, 1000, 5000, 10,000, 20,000 and 40,000 ppm were 2 × 10-4, 1.98 × 10-4, 1.60 × 10-4, 1.60 × 10-4, 1.16 × 10-4 and 1.13 × 10-4 respectively. Thus, in the present study, it is concluded that 2,4-D was more effective in inhibiting macromolecular synthesis while glyphosate and stomp have the less inhibitory effect on protein as compared to 2,4-D.
