This study scientifically analyzed the graft union strength and anatomic-morphological compatibility patterns of columnar apple varieties grafted onto rootstocks with varying biological growth vigor (clonal rootstocks MM106, M9, MM111, and wild seedlings). By testing saplings harvested from the second field of the nursery using a dynamometric device, the mechanical breaking force of the graft components was determined, and the trunk compatibility indices were evaluated during the vegetative period. The results revealed that the semi-dwarfing rootstock MM106 provided the most optimal mechanical stability (averaging 16.7 units) and ideal anatomical harmony (index 0.98) for the studied columnar varieties. Conversely, the dwarfing rootstock M9 induced significant overgrowth and thickening at the graft union (index 1.12), which was accompanied by a noticeable reduction in structural strength.
