秋季以~(14)C喂饲红星苹果幼树,矮化中间砧树地上部~(14)C同化物质相对量高于根系,高于乔砧树。休眼期仍高于根系,高于乔砧树,主要贮存于多年生枝和一年生枝,根内较少。新梢不同部位及叶片内其含量由下往上递减,显著高于乔砧树。一年生枝由上往下递减,养分积累期和休眼期高于乔砧树。矮化中间砧段对~(14)C同化物质的输送有滞阻作用,从而影响地上部和根系的生育、花芽的形成、产量和果实品质。
The autumn ~ (14) C feeding Red Star apple saplings, dwarfing middle rootstock to the upper part of the (14) C assimilation relative amount higher than the root, higher than Joe anvil trees. Rest eye still higher than the root system, higher than Joe anvil tree, mainly stored in perennial and annual branches, root less. Shoots in different parts of the leaves and its content decreased from bottom to top, significantly higher than the Joe rootstock tree. Annual branches descending from top to bottom, nutrient accumulation and rest period is higher than the Joe rootstock tree. The dwarfing middle anvil segment had a retarding effect on the transport of the ~ (14) C assimilative substance, which affected the growth, flower bud formation, yield and fruit quality of shoots and roots.
