To know the influences of the bud and leaf of the slip on the formation and growth of root in tea cutting, the following examinations were performed. Yabukita variety was used, and the slips which had 3 nodes, 2 buds and 2 leaves were used as a standard plot. Removing 0-1 leaf and 0-2 buds from the standard slips 7 plots were designed, and 1 plot which had 4 nodes, 3 leaves and 3 buds was added. Cutting was done on 15 th, July, and the investigations were made on 110 and 150 days after cutting. The number of roots was most numerous in 3 or 2 buds plots and least in 0 bud plot, but the influence of the leaf on the number of roots was not observed. In the slips which had one bud, more numerous roots were found on the side of stems where the bud attached than on that of no bud Concerning the weight ht of roots, the tenden cy that the more the leaves the heavier the roots was observed, though there also existed some iufluences of the bud upon them. This tendency was observed more distinctly in the results obtained on 150 days after cutting than in that of 110 days. From the results written above, it may be said that in tea cutting the bud on the slip affects mainly on the root formation, and the leaf mainly on the root growth.
