枳(学名 Poncirus trifoliata)是世界上柑桔类使用最广的第三种砧木。树势健旺,最耐寒、耐涝,且抗耐退化病、柑桔线虫及若干种 Phytophora 疫菌,因此在育种上多用来杂交培育抗病砧木。枳砧嫁接苗结果早,丰产,果实品质优良,酸和可溶性固形物含量高,富于风味;且植株矮化(据在里佛赛德的柑桔研究中心测量表明,Rubidoux 枳砧华盛顿脐橙的树冠体积为甜橙砧华脐冠积的54%,Rubidoux 枳砧伏令夏橙冠积为甜橙砧伏令夏橙的58%),有利密植,采果、病虫防治等操作也较方便、省工。
Trifoliate Poncirus trifoliata is the third most widely used rootstock in the world for citrus. Tree vigor, the most cold, waterlogging, and resistance to degenerative diseases, Citrus nematodes and several Phytophora bacteria, so in breeding more used to cultivate resistant rootstocks. Trifoliate orange seedlings have early, high yield, good fruit quality, high levels of acid and soluble solids, and rich flavor; and plant dwarfing (as measured by the Citrus Research Center at Riverside, showing that the Rubidoux The crown volume is 54% of the total volume of the umbilical cord of the sweet anvil, Rubidoux is the best for the sweet orange with 58% of the summer orange, which is advantageous for the close planting of fruit, fruit picking and pest control , Labor.
