Physico-chemical changes during fruit growth and developmental stages in yellow type passion fruit (Passiflora edulis f. flavicarpa Degener) accessions

Abstract

Physiological and biochemical changes during fruit growth, development and maturity of six yellow type passion fruit (Passiflora edulis f. flavicarpa Degener) accessions were studied at weekly interval after fruit set from 21 days to 91 days after fruit set and after dropping from vine also. Fruit growth of passion fruit followed a single sigmoid growth curve. Fruit length (cm), diameter (cm) and weight (g) increased continuously (25.24%, 33.13% and 75.08% respectively) (from the initial stage till maturity up to 84 days), which slightly declined at ripening stage. Fruits developed acceptable physico-chemical qualities with good colour, when harvested at 84 to 91 days after fruit set (DAF). The study further revealed that the days taken from fruit set to maturity and ripening, colour change, total soluble solids and acidity may be considered as the most reliable maturity indices for taking harvest decision in pas-sion fruit.

Passion Fruit—A Potential Crop for Exploration in Malaysia: A Review

“…Ideally, fruit maturity indices involve non-destructive measurement, simple to measure by producers, handlers, and quality control personnel, which are readily performed in the field with nonsophisticated instruments (Lina et al, 2014). Specific criteria have been outlined for passion fruit maturity indices released by commercial producers such as America, Brazil, and Kenya (Ghosh et al, 2017).…”
