研究结果表明，苹果树矮化中间砧对14C同化物质的运转有明显的滞阻作用。喂饲当年报制14C同化物质下运，翌年限制根系内14C同化物质上运。矮化中间砧段内积累较多14C同化物质，矮化中间砧苹果树地上都大部分时间14C同化物质含量显著高于根系，从而影响地上部和根系的生育、花芽分化、产量和果实品质。
The results showed that the dwarfing apple stump had a significant hindrance to the 14C assimilation. Feed the reporting system 14C assimilation material shipped, the following year to limit the root system 14C assimilation material shipped. The accumulation of 14C assimilation material was more in dwarfing middle anvil section. The content of 14C assimilation substance in the ground of dwarfing interstock apple tree was significantly higher than that in root system most of the time, which affected the growth, flower bud differentiation, yield and fruit quality of shoot and root.
