抄録

The experiment was made for clarifying the histological processes of graft union between melon or watermelon which was used as the scion and pumpkin or squash which was used as the stock. 1. On the 2nd day after the operation, parenchyma near the graft junction has reverted to a juvenile condition and begun to devide; particularly so in case the vascular elements of the scion had occurred to be brought into contact with those of the stock. 2. On the 4th day, a partial union has been induced directly at the graft junction, almost without forming any cullus tissue between the stock and the scion, and the vascular elements newly differentiated from both of the graft components have been connected with each other. 3. Generally, the multiplication of parenchymatous cells and the differentiation of vascular elements in the graft union seemed to begin earlier on the part of the scion than on the part of the stock, otherwise to occur in parallel with each other.
