PRELIMINARY DATA ON INFLUENCE OF SIX CITRUS ROOTSTOCKS ON FRUIT QUALITY OF 'LANE LATE' NAVEL ORANGE
Seven-year-old trees of Lane Late grafted on three new citrus rootstocks: Forner-Alcaide n°5 (FA5), Forner Alcaide n°13 (FA13) and Forner-Alcaide n°41 (FA41) (hybrids of Cleopatra mandarin × Poncirus trifoliate), and three traditional rootstocks: Carrizo citrange (Citrus sinensis × Poncirus trifoliate), Alemow (Citrus macrophylla) and Cleopatra mandarin (Citrus reshni), cultivated in Andalusia (Spain), were evaluated in the season 2010-2011. They were characterized as their effects on fruit appearance, taste and nutritional compounds. FA5 and Cleopatra madarin maintained fruit quality on the tree for longer time, indicating that they are the most suitable for late harvested cultivars such as Lane Late. Alemow and Carrizo citrange showed a faster loss of organoleptic quality due to their lower acidity of the juice. Alemow produced larger fruits than Cleopatra mandarin and FA13, although it also produced the lowest juice content and the poorest organoleptic quality. In relation to the remaining quality parameters, Alemow and Carrizo citrange had the lowest values in fruit firmness, total polyphenols content and antioxidant activity. Cleopatra mandarin, FA13 and FA5 had the highest antioxidant activity, while FA13 showed the highest fruit firmness, similar to FA41 and FA5.
