Abstract
1) Both the total Weight and the average weight of seeds in the pulse were found heavier at the nodes nearer to the base of the plant and became lighter in accordance to the height of the position. The total seed weight for single node were often found heaviest at the third or fourth node ; the relation of seed weights to the order of nodes might be represented by a monomodal curve. 2) The increasing rate of the total weight or the average one of the seeds are shown in Fig. 1 and 2. Trans location of nutrients into seed grains seems to be faster at the lower nodes on the branch. 3) The grain of the first flower in a cluster became heavier than those of the second or third flower, though they bloomed on the same day.
