RESULTS OF EIGHT YEARS OF RESEARCH ON THE GROWTH AND YIELD OF THREE SWEET CHERRY CULTIVARS GRAFTED ON ‘PHL A’ ROOTSTOCK

The aim of the presented work was to determine the pomological value of a new Czech sweet cherry rootstock – ‘PHL A’, and its usefulness for three sweet cherry cultivars: ‘Burlat’, Büttner’s Red’ and ‘Kordia’. The experiment was set up in the spring of 1994 in the Experimental Orchard at Dąbrowice near Skierniewice.
One-year-old maidens of the three sweet cherry cultivars grafted on the ‘PHL A’ rootstock and on Prunus avium seedlings (used as a control) were planted at 5 x 2 m on a light podzolic soil with a clayey subsoil.
The ‘PHL A’ rootstock was compared with Prunus avium seedling, which is traditionally used as a rootstock for sweet cherry trees.
The trees of the three investigated cultivars grafted on ‘PHL A’ grew more slowly and were more productive in comparison to the control trees.
The ‘PHL A’ rootstock slightly accelerated the ripening time of fruits and favourably influenced their colour.
No obvious effect of the type of rootstock on fruit weight of the three cultivars was found.
