Özet
This study was carried out to determine the cutting properties of different wine grape canes as a function of moisture content, canes' diameter and variety. Cutting properties of cutting force, cutting strength, cutting energy and specific cutting energy were measured in eight different wine grape varieties. Canes of 'Tannat', 'Merlot', 'Cot', 'Chardonnay', 'Viograier', 'Cabernet Sauvignon', 'Shiraz' and 'Cabernet Franc' were profiled for their cutting properties during the dormant season. The results of data analysis showed that there was a significant difference between mean values of cutting properties varying based on variety. The results demonstrated that the maximum cutting force, cutting strength and cutting energy for 'Cabernet Franc' grape variety were 1397.60 N, 21.68 MPa and 3.68 J, respectively. The minimum cutting force, cutting strength and cutting energy were obtained at 'Tannest' grape variety and it was 981.65 N, 13.94 MPa, and 2.39 J, respectively. Whereas, the maximum specific cutting energy obtained at 'Chardonnay' was 0.256 Jmm-2, while the minimum specific cutting energy obtained at 'Tannat' grape variety was 0.219 Jmm(-2). In conclusion, findings demonstrated that the cutting properties were related to the physiological, physical and mechanical properties of the grew. branches. Therefore, the grape variety should be taken into account for the design of a suitable pruner machine.
