Özet

The objective of this study was to determine Fruit Detachment Force/Fruit Weight (FDF/W) ratios of fruits and spring rigidities of Yomra variety hazelnut limbs. With this objective, changes in detachment forces and weights of fruits according to the maturity time of fruit ripening periods and changes in spring rigidities according to the limb diameters and limb connection points were determined. FDF/W ratios were found as 1.21-3.59 Ng(-1) on August 28th, 0.78-3.09 Ng(-1) on September 7th and 0.57-2.16 Ng(-1) on September 15th. Spring rigidities varied between 0.13-2.51 Nmm(-1) depending on increase in limb diameters and decrease in limb connection points.
