In the present study, the basic fruit quality indicators, including fruit mass, pulp content, fruit shape index, sweetness and pH of fresh passion fruits from three areas of China were determined. The results showed that with different areas and extended storage time, the values of the quality indicators and the appearance of the fruits changed drastically. The fruit skins gradually wrinkled, and lesions appeared on some of the fruit surfaces. The fruit mass, pulp mass and sweetness of all significantly reduced, whereas the pH increased. The average fruit shape index of the three groups were 1.09, 1.13 and 1.15, respectively. Sample 1 was round-shaped while sample 3 was more elliptical.In addition, the ratios of grade superior fruits from the three production areas were 65, 75 and 60%, respectively, and the ratio of grade I fruits were 35, 25 and 40%, respectively. Based on these basic indicators, it is concluded that the growth conditions had a certain effect on the sweetness and quality of passion fruits. Meanwhile, different growth conditions of passion fruit provide varieties of flavors, thus enriching the market diversification and satisfying various taste needs from a variety of consumers.
