Summary
This experiment was conducted to evaluate the relationships among root activity, photosynthetic activity and yield of soybeans. Except alpha-NA oxidizing activity, P-32 absorption rate, root respiration rate and succinate dehydrogenase activity were concurrent to relate with the photosynthetic activity of soybean plants. Morover, soybean cultivars with high grain yield could obtain high shoot-growth potential while plants were passing through pod-filling stage and plant height stopped early before this stage. In low grain yield cultivars, plant height was still incrasing, while shoot weight was stopped growing 5-10 days before pod-filling stage. It is suggested that the higher root activity of soybean in pod-filling stage could be a reliable selection index for grain yield purpose. [AS]
