The study researched the influence of four vegetative rootstocks on a biological and production properties of sweet cherry cultivar ‘Regina’. The study was carried out during fourth and fifth growing years at an orchard located at the experimental estate “Radmilovac” of the Faculty of Agriculture in Belgrade. Cultivar ‘Regina’ was grafted on the following rootstocks: ‘Gisela 6’, ‘Ma×Ma 14’, ‘Colt’ and ‘Oblačinska cherry’, while trees grafted on P. mahaleb used like a control. The highest yield had trees grafted on rootstock ‘Gisela 6’ (6.5 kg), while the smallest yield had trees grafted on seedlings of P. mahaleb (1.4 kg). Cultivar ‘Regina’ had the highest number of sper fruiting branches on ‘Colt’ (367.2) and the smallest number was recorded on P. mahaleb (154.8), while number of lateral fruiting branches on trees of cultivar ‘Regina’ was between 91.6 (‘MaxMa 14’) and 42.2 (‘Oblačinska cherry’). The highest content of soluble solid matter and sweetness in fruit were on the trees grafted on P. mahaleb. |
