Abstract

Dimensional, optical properties and volume of agricultural products are the most important parameters in the design of postharvest equipment. In this study mass of plum fruit was estimated with using selected physical properties in linear and non-linear models. The result showed that the selected properties which were determined in this research such as length, width, thickness, geometric mean diameter, sphericity, mass, volume, projected areas and surface area values of Santa Rosa variety were significantly (p < 0.01) greater than for Can variety except for fruit density. For the practise applications, for estimating the mass of plum fruit, the thickness for Can and width for Santa Rosa can be used. The models based on projected are , R2=0.934, RMSE=0.891 for Can variety, , R2=0.961, RMSE=1.300 for Santa Rosa variety had highest R2 among the others, can be used. In third classification, the best model was obtained on the basis of the oblate spheroid volume as , R2= 0.981, RMSE=0.507 for Can variety and , R2=0.959, RMSE=1.326 for Santa Rose variety.
