Resumo: | 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 persimmon fruits and correlating the mass of persimmon fruits to measured physical properties using linear, quadratic, S-curve and power models as three different classifications: (1) Single variable regressions of persimmon dimensional characteristics, (2) single variable regressions of persimmon mass based on projected areas and (3) estimating the persimmon mass based on its volumes.  The results showed that mass modeling of persimmon based on length and the first projected area were the most appropriate ones in the first and the second classifications, respectively.  In third classification, Linear Quadratic and models based on volume of the fruits assumed as ellipsoid shape (Vellip) with R2 =0.880, were the best models for mass prediction of the persimmon based on volumes as: M =15.933+ 0.001Vellip and M =15.933+ 0.001Vellip + 5.569×10-10.  In the economical and agronomical point of view, suitable grading system of persimmon mass was ascertained based on length as Quadratic form: M = 356.171−12.664L+ 0.136L2, R2 = 0.960.   Keywords: persimmon fruit, physical characteristics, mass prediction
