The quality of apple fruits is influenced by variety and within each variety by the rootstock and by the culture technology applied. The research presented in this paper highlighted the influence of the rootstock on the fruit quality. The experiment was conducted during 2016-2017 in the Vâlcea plant nursery, in Romania, as a comparative study for the ʻPinovaʼ variety with several rootstocks (M9, B9, M20, Pi80, M106), including variants with grafting interstems (B9/A2, B9/M111). The size of the fruit was larger for the trees grafted on the rootstock B9 with the interstem M111, while the firmness was positively influenced by the rootstocks M9 and B9/A2. The content of soluble dry substance was favourably influenced by the rootstocks M20, B9 and Pi 80, while the titratable acidity had higher values for the fruits produced by the trees grafted on M106 and M9/M111. The total anthocyanins content was higher for the fruits obtained from the trees grafted on the rootstock B9 with the interstems M111 and A2.
