QUALIDADE FÍSICO-QUÍMICA DE FRUTOS DE MARACUJAZEIRO EM FUNÇÃO DAS FORMAS DE PROPAGAÇÃO E POTENCIAIS DE ÁGUA NO SOLO

Abstract

In the present study, the physicochemical quality of passion fruit (Passiflora edulis Sims, ‘BRS Gigante Amarelo’) propagated from seeds or cuttings and subjected to different soil water potential were evaluated. The experiment was carried out in a greenhouse, between November 2019 and June 2020, at the Federal University of Recôncavo of Bahia, Cruz das Almas, BA. The passion fruit was grown in drainage lysimeters, each one with a surface area of 1.44 m² and 0.6 m high, and filled with sandy loamy soil. The experiment was carried out in a completely randomized design in a 2 x 4 factorial scheme: two forms of vegetative propagation (seed or cuttings) and four soil water potential (-6, -10, -20 and -33 kPa), with four replicates. Fruit fresh weight, fresh weight of the fruit pulp, fruit diameter and length, fruit length/diameter ratio, fruit pulp yield, rind thickness, total soluble solids, total titratable acidity, total soluble solids/total titratable acidity ratio and pH of the pulp were evaluated. The forms of propagation affected the main physical quality variables of the fruits of passion fruit. The chemical quality of the passion fruit pulp was not affected by the factors under study.
