摘要
从形态解剖、水分及营养物质运输、同化异化生理及激素调节等几方面，综述了苹果矮化砧木致矮机理的研究成果。结果表明，苹果砧木致矮的机制不止一种，但核心不明。今后研究应着重在激素类物质的产生、运输、降解及水分代谢与相应的生理变化等方面进行。
The programs on dwarfing mechallism of apple dwarfing rootsticks were briefly re-viewed.consisting of anatomy, transformation of water and nutrition, physiology and the control of endogenous hormons. It shuld be concluded that more than one mechanism makeatree dwcqrf,but the most effective was still unknown. In the further studies,the emphasiswould be on the produetion,transformation and the breakdown of hormons and also watermetabolic and the induced physiological reactions.
