PROBLEM TO BE SOLVED: To provide means which is capable of preventing a root from being generated from a lower end part of a scion in a rootstock and extending downward, and grafting the scion and the rootstock approximately coaxially, easily and accurately while preventing them from being misaligned.SOLUTION: A grafted seedling 1 is formed by grafting a scion 2 and a rootstock 3 approximately coaxially. A protrusion part 4 is formed on a lower end vicinity part of the scion 2. On the other hand, a recess part 5 is formed on an upper end vicinity part of the rootstock 3. Herein, the protrusion part 4 and the recess part 5 are formed into complementary shapes, and the scion 2 and the rootstock 3 are grafted in the state where the protrusion part 4 is inserted into or fitted with the recess part 5. The protrusion part 4 is defined by a V-shaped peripheral surface 6, a first V-shaped external surface, and a second V-shaped external surface. The recess part 5 is defined by a first V-shaped internal surface and a second V-shaped internal surface.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】穂木の下端部から根が発生して台木内で下向きに伸びるのを防止することができ、かつ穂木と台木とを、これらが互いにずれるのを防止して略同軸状に容易かつ正確に接合することを可能にする手段を提供する。【解決手段】接木苗1は穂木2と台木3とが略同軸状に接合されてなる。穂木2の下端近傍部には凸部4が形成されている。他方、台木3の上端近傍部には凹部5が形成されている。ここで、凸部4と凹部5とは相補的な形状に形成され、凸部4が凹部5に挿入ないしは嵌入された状態で、穂木2と台木3とが接合されている。凸部4は、V字形周面6と、第1のV字形外面と、第2のV字形外面とで画成されている。凹部5は、第1のV字形内面と、第2のV字形内面とで画成されている。【選択図】図3
