Rootstock - Daigi (English name) stock

Japanese: 台木 - だいぎ（英語表記）stock

The part where the scion is joined in grafting. Grafting is when the scion and rootstock are joined together and coexist, and the rootstock affects the growth, chemical composition, germination, flowering time, and fruit set of the scion, and the rootstock is also influenced by the growth and morphology of the scion. There are three types of rootstocks: those made from the same species as the scion (common rootstocks), those made from plants resistant to specific diseases and pests (immune rootstocks), and those made from plants resistant to specific diseases and pests (dwarf rootstocks), which dwarf the plant and speed up fruit set. Tree species used include apples - Mitsubakaido and Marubakaido; citrus fruits - trifoliate orange and yuzu; and pears, peaches, chestnuts, persimmons, plums, plums, and apricots - common rootstocks. They are mostly grown by seed, but can also be grown by layering and cuttings.

接木繁殖で接穂を接合する部分のこと。接木 (つぎき) は接穂と台木が接合されて共生することであり，台木は接穂の発育，化学的組成，発芽，開花期，結実性などに影響を与え，また接穂から根の発育や形態について影響を受ける。接穂と同種の植物を使う共台 (ともだい) ，特殊な病虫害に強い植物を使う免疫性台木，矮小化して結実を早める矮性台木の3種がある。用いられる樹種は，リンゴ──ミツバカイドウ，マルバカイドウ。柑橘──カラタチ，ユズ。ナシ，モモ，クリ，カキ，ウメ，スモモ，アンズ──共台，などである。育成は多くは実生繁殖によるが，取木，挿木による場合もある。
