Influence of elevated level of CO2 on biochemical parameters of Glycine max (L.) merr. inoculated with Bradyrhizobium japonicum

Effect of elevated co2 with bradyrhizobium japonicum strain (kucc-118) on somebiochemical parameters of soybean (glycine max (l.) merr was studied. the sterilized seeds of glycine max were coated with bradyrhizobium japonicum. the seedling of soybean was fumigated with 2% (20000ppm) and 3% (30000ppm) co2 for 10 and 20 mins.,duration. seedlings were exposed twice a day in a week to elevated co2. the 3% (3000ppm) co2 fumigated plants showed weekly reduction in carbohydrate,total protein,total dna and total rna as compared to the exposure of 2% (2000ppm) concentration of co2. control plants which were grown in ambient level (330ppm) of co2 with inoculation of bradyrhizobium japonicum showed significant increase in biochemical parameters.
