Abstract
The influence of rootstocks Prunus mahaleb seedling, MaxMa 14 and Gisela 6 on the course of different phenophases in sweet cherry cultivars ‘Burlat’, ‘Van’ and ‘Katalin’ was studied in the period of full bearing over four growing seasons.
The experimental orchard was established in 2014 in South Bulgaria near the town of Plovdiv in a typical cherry-growing region with relatively low fertile soil with drip irrigation provided.
The obtained results showed that the rootstock Gisela 6 significantly delay the flowering and ripening period of the cultivars includedin the study.
Contrary to the common belief that fruit trees have no visible development during the dormancy period, we noted that rootstocks Prunus mahaleb seedling and MaxMa 14 had significantly increased their diameter compared to Gisela 6 during the dormant period.
Activity in the dormant period was also presented in the cultivars.
During this period they increased their diameter more intensively when grafted on Prunus mahaleb seedling and MaxMa 14 than if they were combined with the rootstock Gisela 6 and thus form significantly thicker stems.
In the three cultivars included in the study, the weakly growing rootstock Gisela 6 induced 25-30 days earlier end of vegetation compared to Prunus mahaleb seedling, and the rootstock MaxMa 14 took an intermediate position in this parameter.
