Correlations between production and quality characteristics of the yellow passionfruit selection 'Ovalado Grande' in southern Brazil
This work is aimed at evaluating the correlations between production and quality characteristics of yellow passionfruit in southern Brazil, city of Pelotas/RS. The selection 'Ovalado Grande', developed for mild climate, was used. The planting, at 1600 plants ha-1, was carried out in October 2011. Vines were trained on espalier trellises. Drip irrigation was provided and flowers were pollinated manually. The experiment was divided into variables of production: productivity, production plant-1, number of fruit plant-1, number of fruit ha-1 and fruit weight; and physicochemical variables: fruit length, fruit width, pericarp thickness, pulp yield, soluble solids, citric acid, skin color and the ratio soluble solids/citric acid. There were significant correlations between productivity and production plant-1 (r=0.99), productivity and number of fruit ha-1 (r=0.93), fruit weight and number of fruit plant-1 (r=-0.88), fruit weight and number of fruit ha-1 (r=-0.89). For the physicochemical fruit variables, there were significant correlations between soluble solids and fruit length (r=0.90), and between pericarp thickness and fruit width (r=-0.91).
