Brassinolide (BL) and Jasmonic acid (PDJ) are plant hormones and play various roles in plant growth and development. The effects of their exogenous application on the flowers and pods of soybean are examined. Soybean (cv. Tamasudare-2) was sowed in plastic case, and one-week old seedlings were transplanted in the field to grow until harvesting. Both hormones were applied at 10 days before flowering or at the beginning of flowering. The numbers of pods were decreased by brassinolide application, especially applied at the beginning of flowering, due to the decrease of the rate of podding. Jasmonic acid application increased the number of pods with the increase of the number of flowers, though the number of seeds in a pod was reduced null or one in many pods.
