Physical properties of pomegranate fruits

The physical properties of twenty fruits of each of five cultivars of pomegranate were deter-mined. The properties determined were the weight, volume, diameter, surface area, weight density, and sphericity. The statistical analysis indicated that there was no statistically significant difference between the five cultivars in weight, volume surface area, and sphericity. However, the densities were statistically different at the probability level of 0.12%. The difference in mean diameter of the various cultivars was also statistically significant at the 5% level. Prediction equations to compute the surface area and volume using the weight or the mean diameter of the fruit were obtained
