A Cherry is a forest tree. It has a high propensity for large tree formation and apical dominance. So, the tree must be shaped by pruning. There are lots of cut types for the pruning of cherry trees. But heading cuts and thinning cuts are known as two basic cut types. Heading cuts are the shortening of the terminal part of the shoots. Thinning cuts are defined as the total removal of the shoot. In cherries, many rootstocks make trees of different sizes, such as Gisela 3, Gisela 5, Gisela 6, PHL-C, PiKU 1, PiKU 3, CAB 6P. The importance of heading cuts in rootstocks such as PHL-C and Gisela series has been demonstrated by many studies. But there is no information in the literature on whether to make a heading cut on semi-dwarf rootstocks such as PiKU 3 and CAB 6P. In this study conducted in Samsun between 2019 and 2020, aim is to determine the effect of heading cuts on growth, yield, and fruit quality on ‘Regina’/CAB 6P and ‘Summit’/PiKU 3, variety/rootstock combinations. Phenological observations and morphological measurements of the cherry cultivars grafted on different rootstocks were carried out. In addition to spur and fruit number, fruit weight, fruit width, fruit firmness, soluble solids content, color values, yield values per tree and per decare were determined. As a result of the research, it was determined that the heading cutting did not affect these combinations in terms of the relevant parameters. However, the data and observations taken from the experiment show that the heading cut increases the number of lateral shoots and makes the shoot lengths more reasonable.
