MEDEIROS, Sidney Almeida Filgueira de et al. Physico-chemical characteristics of purple and acid-passion-fruit genotypes grown in Brasília. Rev. Bras. Frutic. [online]. 2009, vol.31, n.2, pp. 492-499. ISSN 1806-9967. http://dx.doi.org/10.1590/S0100-29452009000200025.
Fruit quality for fresh passion fruit is a key factor for commercialization in European market. Aiming to evaluate the physico-chemical characteristics of passion fruits grown under Savanna condition an experiment was carried out using a randomized design with nine treatments and four replications. The treatments consisted of nine cultivars and selections (seven purple- and two acid-passion-fruit). The purple-genotypes ('Lacey', '14', '25', 'Supersweet 9', '37(1)', '37(2)' and '96A' ) are from Australia and the yellow-ones ('Marília Seleção Cerrado' and 'Híbrido EC-2-0') from Brasília, Brazil. The selection '32(2)' showed the highest content of TSS; 'Lacey' the thinnest peel and a more round fruit shape; and 'Marília Seleção Cerrado' the largest number of seeds per fruit and the heaviest pulp weight. Among the purple-genotypes selection, 'S9' showed the heaviest pulp weight, the highest pH and the lowest TA. The Yellow pulp color was predominant. Positive correlation for pulp weight and TA and inversely for pH and TA were observed.
