Datura Tatula, D. Metel, and D. meteloides were grafted on each other obtain Tat./Met., Met./Tat., Tat./met., and met./Tat. These plants were cultivated with a definite amount of fertilizer and were harvested when fully grown to examine the degree of growth and the yield. Variation in content of the componental alkaloids, i.e. hyoscyamine, scopolamine, and meteloidine, was also examined. It was thereby found that the rate of the growth was comparatively near the yield of D. Tatula while the varition in the ratio of alkaloidal content in leaves was approximately those in D. Metel and D. meteloides. It was concluded that not only the root plant but also the specie of the grafted plant had largely affected the alkaloidal content of the plants. There was little variation of alkaloidal content in the roots, showing about the same ratio as the roots in the control area and not so marked an influence of the grafted plant. In other words, it may be concluded that the variation of the alkaloidal content in Datura spp. was affected not only by the root but also by the function of the leaves.
