ABREU, Simone de Paula Miranda; PEIXOTO, José Ricardo; JUNQUEIRA, Nilton Tadeu Vilela and SOUSA, Marcelo Alves de Figueiredo. Physical-chemical characteristics of five genotypes of yellow passion fruit cultived in brasília . Rev. Bras. Frutic. [online]. 2009, vol.31, n.2, pp. 487-491.

The aim of this work was to evaluate the physical-chemical characteristics of five genotypes of passion fruit cultived in Brasília in three seasons: February, March and April of 2005. The experiment wascarried out in the experimental area of the Água Limpa Farm of the UnB, Brasília-DF. It was used the delineation blocks with four repetitions, five genotypes, three evaluation periods and seven useful plants per share. The five genotypes were evaluated: Rubi Gigante, EC-3-0, EC-L-7, Redondão and Gigante Amarelo. The fruits produced on April/2005 present greater length, fresh fruit of mass, pulp, and juice, titrable acidity, pH and number of seeds. Genotype Rubi Gigante presents fruits with lesser length and highest soluble solids. Genotypes Redondão and Gigante Amarelo present fruits with lesser relation length/diameter. The genotypes Gigante Amarelo and Redondão consequently present fruits with a lesser thickness of the rind and the highest ovarian socket, with a highest amount of pulp. This last genotype also got fruits with the highest diameter, soluble solid and lower pH. This characteristic is important for processing; therefore fruits with high acidity present a reduction in the addition of acidifying in juice. The prolongated format predominated in the fruits of the five genotypes at the three analyzed periods.
