| Abstract: | The young trees of Starking Delicious were fed with ~(14)C in autumn,and ~(14)C distributionin the following year was studied.The results showed that the difference between the ~(14)Ccontents in above ground part and root of the tree grafted on dwarfing rootstock at emer-gence stage,was greater when compared with trees on standard stock.The anatomy struc-ture difference between stock and scien was greater in dwarfing combination than in the stan-dard trees.The moving up of the ~(14)C assimilates was retarded due to function of tree ondwarfing rootstock,leading to the inhibition of the vegetative growth in the early season. |
