Abstract
Three sweet cherry cultivars (Sunburst, Kordia and Regina) grafted onto the seedling rootstock Prunus mahaleb were used to study the effects of cytokinin (6-BA) and a mixture of cytokinin (6-BA) and gibberellin (6-BA+GA 4+7 ) on the improvement of branching of 'knip' nursery trees. The plant growth regulators were applied to the upper third of the nursery trees three times in June at concentrations of 0, 500, 1,000 and 1,500, using 5 ml of solution per tree per treatment. At the end of the vegetation period, the trunk cross-sectional area (TCSA), the height of the tree and the number and quality of lateral branches were measured and evaluated. In Kordia and Regina varieties, the application of plant growth regulators (PGR) had no effect on the diameter, height and average length of the feathers of the nursery trees. However, 6-BA at a concentration of 1,500 mg l -1 and 6-BA+GA 4+7 at concentrations of 1,000 and 1,500 mg l -1 significantly increased the total length of all feathers, their total number and the number of feathers longer than 30 compared to the untreated treatment. In Sunburst variety, all treatments applied increased the total number and the number of feathers longer than 30 compared to the untreated treatment, with both values being highest in the 6-BA 1,000 and 1,500 mg l -1 treatments. These treatments also significantly increased the total length of all feathers compared to the control treatment.
