Influence of different rootstocks on yield precocity and fruit quality of 'Tarocco Scirè' pigmented sweet orange

In this study, the important role of rootstock in determining the organoleptic quality, specifically the sugar content, and the anthocyanin concentrations in both the pulp and the juice was demonstrated. Some of the rootstocks that were recently introduced in Italy, i.e., 'Bitters' and 'Furr', were promising because they positively influenced several agronomic and qualitative parameters in the tested conditions, positively affected the yield precocity and enhanced the fruit juice anthocyanin content. Overall, these results contribute to the assessment of the role of different rootstocks in the post-CTV Italian citrus industry.
