The present investigation deals with the influence of 2,4-dichlorophenoxy acetic acid (2,4-D)on macromolecular synthesis, i.e. DNA, RNA and protein content of weed Psoralea corylifolia L. belonging to family Fabaceae. It is commonly known as ‘Bawachi’ growing in a wild and cultivated field in Vidarbha region of Maharashtra State, India. The macromolecular content of seeds was treated with different concentrations of 2,4-D and grown to get seedlings. Six days old seedlings were tested for DNA, RNA and protein content. As the concentrations of 2,4-D increased the percentage of DNA, RNA and protein content gradually decreased. The percentage of DNA decreased from 6.96×10-3 to 4.02×10-3 at 100 to 1000 ppm respectively. The percentage of RNA in treated seedling decreased from 9.18×10-2 to 3.20×10-2 at 100 to 1000 ppm respectively. The percentage of protein gradually decreased from 5.24 to 2.32 at 100 to 1000 ppm respectively. The percentage of DNA, RNA and protein content of control seedlings were 7.20×10-3, 9.80×10-2 and 6.35 percent respectively.
