嫁接在同一基砧不同中间砧上的玫瑰红苹果树的光合速率有明显差异。叶幕形成期矮化性强的Ｍ９、Ｍ２６中间砧组光合速率高；叶幕形成后的不同时期，以Ｍ４、Ｚｉ和Ｍ７３种中间砧组光合速率较高，稳定性亦较好，Ｍ２６、ＭＭ１０６中间砧组光合速率最低．稳定性最差．各中间砧组合光合速率年周期变化动态趋势不同，Ｍ４、Ｍ９中间砧组９月下旬至１０月下旬为上升型，Ｍ２６、ＭＭ１０６中间砧组为下降型，Ｍ７、Ｚ１中间砧组为相对平稳型。各中间砧组光合速率差异与叶的发育状况及单株产量无关。利用Ｍ４、Ｚｉ、Ｍ７作中间砧是提高元帅系短枝型苹果树光合速率的一条栽培途径。
There was a significant difference in photosynthetic rate of rose apple tree grafted onto the different anvils of the same rootstock. The photosynthetic rate of the dwarfing dwarf M9 and M26 middle anvil group was high at the leaf curtain stage. The photosynthetic rate of M4, Zi and M73 middle anvil group was higher at different stages after the leaf curtain was formed, MM106 intermediate anvil group the lowest photosynthetic rate. The worst stability. The dynamic trends of photosynthetic rate annual change of the middle anvil were different. The M4, M9 middle anvil group were ascending type from late September to late October, the M26 and MM106 intermediate anvil group were descending, while the M7 and Z1 intermediate anvil group was relatively stable . The differences of photosynthetic rate among the middle anvil groups were not related to the leaf development and the yield per plant. The use of M4, Zi, M7 for the intermediate anvil is to improve the Marshal Department spur apple tree photosynthetic rate of a cultivation approach.
