Abstract
For proper design of grading systems of horticultural crops, important relationships between the mass and other properties of fruits such as length, width, thickness, volumes and projected areas must be known. The aim of this research was to measure and present some physical properties of green bell pepper fruits and correlating the mass of fruits to measured physical properties using linear, quadratic, S-curve and power models. The results showed that the effects of measured physical properties, on the mass of bell pepper fruit, were found to be statistically significant at 1% probability level. According to the results obtained in this study, the S-curve model could predict the relationships between the mass and some physical properties of green bell pepper fruits with proper values of coefficient of determination. Finally, the S-curve model based of the first projected area (PA1) for mass predication of green bell pepper is suggested because it needs one camera, as the main part of the grading systems and it is applicable and is an economic method.
