Different ‘umbu-cajá’ clones fruit quality

Resumo

This study aimed at evaluating the fruits quality of different clones of umbu-cajazeira. The fruits were har­vested from clones of umbu-cajazeira cultivated in the Experimental Station of the Empresa de Pesquisa Agropecuária do Rio Grande do Norte (EMPARN) located in Ipanguaçu-RN. Completely randomized design was used with six treatments (different clones) and six replications of 30 fruits per clone. Clones evaluated were: Alto do Rodrigues, Serra do Mel, Carnaubais, Assu, Dué, Ipanguaçu. The ripe fruit were evaluated as for fresh mass, longitudinal and transversal diameter, pulp yield, vitamin C, soluble solids (SS), soluble sug­ars, titratable acidity (TA), pH, SS/TA ratio, anthocyanins total and yellow flavonoids. There is a reasonable phenotypic variability among clones, making it possible to indicate the Ipanguaçu and Serra do Mel clones, which produce fruits that gather quality traits favorable (fresh mass, pulp yield, fruit shape, titratable acidity, soluble solids, SS/TA ratio) for the composition of commercial orchards, both for in natura consumption and for industrial processing.
