Effect of 2, 4, D on Seed Germination and Plant Growth of Sorghum cernnum, Triticum aestivum, Vigna radiata and Cicer arietinum

Presoaking is an ancient treatment to increasing seed germination and plant growth index. This treatment was used to examine the seed germination and plant growth index of four crop seeds i. e. Sorghum, Triticum, Vigna and Cicer. Seeds of these four crop presoaked in 000 consider as control and 500, 1000, 1500 and 2000ppm concentration solution of 2, 4, D for constant period of 4 hour. It was shown that there was decline germination % in all four crops except Sorghum 1500ppm solution. Sorghum gave best response in plant growth index in all four concentration. Triticum was found insignificant to increase plant growth and other parameters except 1500ppm solution. In Cicer increased the plant length in 1500 and 2000ppm solution and the number of leaves were increased statistically in all four concentrations as compare to control. 2, 4. D as it shows significant decrease in the germination. It is found inhibitory. Because 2, 4, D is an herbicide it might have shown the inhibitory effect on the metabolism. It is found effective in Cicer to increase number of leaves.
