Abstract

In this study, the correlation between different morphological indicators and physicochemical variables was evaluated. The results relating to the ratios indicate that the density varies from 0.44 to 0.86 g.cm-3 with an average value of 0.69 ± 0.10 g.cm-3. These values reflect a very variable density of the fruits stud-ied. The pulp mass to fruit mass ratio varies from 0.21 to 0.67 with an average of 0.45. This shows that the mass of the pulp represents approximately half of the mass of the fruit. The principal component analysis (PCA) revealed that all the variables are positively correlated. The mass of the fruit, mass of the pulp, and volume of the fruit are strongly correlated while the diameter of the fruit is moderately correlated. The representation of the individuals on the F1F2 plane highlights almost the separation into 3 classes the individuals on the left, center, and right of the F2 axis. By applying the PCA correlation circle of the 4 variables, the two axes represent 97.27% or almost all of the inertia. Three classes seem to appear but not distinctly. The representation therefore highlights three classes of Passiflora fruits edulis flavicarpa, very close. The pulp presents physicochemical parameters in accordance with the exploited standards. Apart from the pronounced presence of vitamin C, this chemotype highlights phytocompounds such as total polyphenols and flavonoids, with acceptable levels of 106 mg GAE/100 g Ms and 59.70 mg ERU/100 g Ms, respectively. These antioxidants are capable of preventing various pathologies.
