ABSTRACT
The market for fresh fruits passion fruit enhances internal and external fruit quality. The use of wild species as rootstocks has been advocated as a possible measure of disease control. Information are scarce on the effect of wild species of the genus Passiflora as rootstocks on physical and chemical characteristics in passion fruits. The objective of this study was to determine the influence of two species of wild passifloraceae, P. mucronata Lam and P. gibertii NE Brow as rootstocks on physical and chemical characteristics of yellow passion fruit in greenhouse. We adopted a completely randomized design with four replications and 25 treatments, consisting of 100 plots. Each plot was represented by a plant conducted in a pot of 30 L. The rootstocks were: Passiflora edulis Sims, Passiflora gibertii NE Brown and Passiflora mucronata Lam. As the control treatment, plants of P. edulis Sims originated from seeds were used. Evaluations of fresh fruit mass (FM), peel fresh weight (PeW), pulp fresh weight (PuW), fruit diameter (FD), longitudinal length of the fruit(LLF), thickness of the fruit skin (TFS), the color of the juice and the fruit peel, soluble solids (SS),titratable acidity (TA), ratio SS/TA, ratio PuW/PeW, vitamin C (ascorbic acid) content. Plants grafted on wild species produced more elongated fruit plants originated from seeds, but within the commercialization standards.
