Abstract
Abstract Grafting the apple variety Pinova on two low vigour rootstocks (B9 and M9) and on two more vigorous rootstocks with B9 as interstock produced different results from the point of view of fruit quality during the first year of production. Average fruit weight was much influenced by the grafting combination; higher weight was obtained for the fruit produced by trees grafted on B9 (186g), while lower fruit weight was obtained for the A2 rootstock with interstock and worked soil (98g). The quality parameters were influenced by the used grafting combinations: the content of soluble dry matter had values between 16-12,2%, fruit firmness was of 7,7-9,54kg/cm2, titratable acidity recorded values of 0,301-0,457mg/100g, and the content of anthocyanins had values of 0,017-0,041mg/100g.
