Resumo
Citrus cultivation is an important agricultural activity in Brazil, with ‘Pera’ sweet orange being the most cultivated sweet orange variety. The selection of suitable rootstocks is fundamental for the success of commercial citrus production, influencing characteristics such as vigor, yield, fruit quality, and disease resistance, as well as enabling high-density planting. Therefore, this study evaluated initial production and fruit quality of ‘Pera CNPMF D-6’ sweet orange grafted onto five rootstocks (‘Indio’, ‘Riverside’, and ‘San Diego’; ‘Sunki-Tropical’ and ‘Swingle’) under three spacings (4.5 × 2; 4.5 × 2.5; and 4.5 × 3 meters). The experiment was conducted in a completely randomized design with a 5 × 3 factorial scheme, evaluated over two productive cycles. Plant height, canopy diameter in the row and between-row directions, canopy volume, total number of fruits, total fruit mass, productive efficiency, and physicochemical fruit quality were evaluated. The citrandarin ‘San Diego’ showed superior performance, with good production performance across both years, reduced canopy volume, and higher productive efficiency, regardless of spacing, and also exhibited high productive efficiency in the intermediate spacing (4.5 × 2.5 m). The results indicate that the citrandarin ‘San Diego’ is a promising rootstock alternative for high-density planting of ‘Pera CNPMF D-6’ sweet orange orchards, with the 4.5 × 2.5 meter spacing being recommended, as it provides high productive efficiency, good production performance, and quality fruit
