EFFECTS OF DWARFING GISELA 5 ROOTSTOCK ON REPRODUCTIVE POTENTIAL, VEGETATIVE GROWTH, AND PHYSIOLOGICAL FEATURES OF SOME SWEET CHERRY CULTIVARS IN HIGH-DENSITY SWEET CHERRY ORCHARDS

Gisela 5 rootstock is most important in terms of reducing the vigor of growth. The varieties grafted on Gisela 5 had good horticultural results in terms of yield, adaptability and dwarf growth. This study was aimed to evaluate the growth and physiological behavior of the most popular sweet cherry cultivars in Europe grafted of Gisela 5 rootstock in one of the most important fruit growing area from Romania. The rootstock – scion combinations namely Skeena, Kordia and Ferrovia were grafted on Gisela 5 dwarf rootstocks. Gisela 5 influenced significantly the trunk cross section area among all the tested cultivars (p
