Abstract
Effect of elevated CO2 with Bradyrhizobium japonicum strain (KUCC-118) on some biochemical 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.
