Acid limes, mandarin and hybrids production in different rootstocks in Acre State, Brazil

Abstract

The objective of this study was to evaluate the behaviour of acid limes ‘Tahiti’ (Citrus latifolia Tanaka) and ‘Galego’ (Citrus aurantifolia Swingle), mandarin (Citrus reticulata Blanco) ‘Cravo’ and ‘Lee’ tangelo and ‘Murcott’ tangor hybrids, grafted on four rootstocks: ‘Rangpur’ lemon (Citrus limonia Osb.), ‘Sunki’ (Citrus sunki Hort. ex Tan.) and ‘Cleopatra’ (Cirus reshni ex Hort. Tan.) mandarin, and ‘Carrizo’ citrange (Citrus sinensis (L.) Osb. x Poncirus trifoliata Raf.). The experiments were carried out at the experimental farm of Embrapa Acre, Amazon, Brazil. The ‘Tahiti’ acid lime presented the highest average of fruit production (115.14 kg/plant), production for canopy volume (2.49 kg m-3) and number of fruits (836.80/plant), for that grafted on the rootstock ‘Sunki’ mandarin. The ‘Carrizo’ citrange and ‘Rangpur’ lime induced on the ‘Galego’ acid lime presented the highest fruits medium production (126.81 e 85.80 kg/plant), production for canopy volume (1.82 e 1.28 kg m-3) and number of fruits (2,619.93 e 1,810.80/plant). The rootstock ‘Rangpur’ lime promoted the highest mean production (90.56 kg/plant) in all mandarin and hybrid cultivars. In spite of the mandarin and hybrids presented the same behavior, the ‘Sunki’ mandarin induced a good average production (69.67 kg/plant) and average number of fruits (500.94/plant) on the ‘Murcott’ tangor.
