Özet:

This investigation was inducted to predict the mass models of cherry laurel genotypes (55 K 07, 61 K 04 and mixed) based on some physical characteristics such as dimension, geometric mean diameter (Dg), the first, second, third projection areas (PA1, PA2, PA3), the criteria area (CAE) and oblate and ellipsoid shaped volumes (Vob, Vell). The analysis was executed using 57 linear regression models for the selected genotypes. The statistical results substantiated that three variables mass model based on major, intermediate and minor diameter (a, b, c) as R2 = 0.876, and R2 = 0.798 can be recommended for mass estimation according to fruit sizes for 55 K 07 and 61 K 04 genotypes, respectively. According to the projection areas, mass models based on the projection areas PA1 + PA2 + PA3 (R2 = 0.881) and PA1 + PA2 (R2 = 0.803) for the 55 K 07 and 61 K 04 genotypes were proposed to estimate the masses. In addition, the mass models based on the Vell (R2 = 0.877) and Vob + Vell (R2 = 0.791) for the 55 K 07 and 61 K 04 genotypes can be used to estimate the masses, respectively. For mixed genotypes, three variables mass model based on a + b + c (R2= 0.964), single variable mass model based on CAE (R2 =0.964), and single variable mass model based on Vell (R2= 0.959) can be recommended, respectively. These models can be used in the design and development of sizing machines for cherry laurel fruits.
