Experimental researches were performed on the growth and yields of kidney bean plants as affected by the treatment of pinching-off one or two of the three leaflets of every leaf at its very young stage. 1) The growth in the stem length was retarded, while the numbers of leaves and flowers were increased by the treatment. 2) The leaflets left on the treated leaves developed generally larger than those of the corresponding positions on the untouched control plants. While the areal ratio among the three leaflets on every normal leaf was nearly 1 : 1:, the ratio between the two leaflets left on every treated leaf was still found to be 1 : 1, not disturbed by the treatment, though they developed respectively larger in their absolute areas. The central leaflet however proved itself somewhat peculiar in areal growth, differing from the side leaflets. 3) There were obseved a tendency that pinching one of the leaflets of every leaf favoured the yield, while to pinch two of them reduced the yield.
