摘要：Grape is an important product for the economy of Turkey and it will continue to play an important role in worldwide grape production due to its large number of varieties, favorable ecological conditions and large production areas. However, pruning and harvesting of grape berries are performed manually with a labor intensive procedure. Therefore, production cost is very high and labor efficiency is low in vineyards. However, pruning and harvesting are the most critical operations in vineyard management. Information regarding the cutting of canes of different grape varieties is very important for a proper harvest machine design as well as the efficient use of energy. In this study, cutting force and cutting energy were measured by considering the factors of grape canes diameter and age of canes. One and two year old grape canes from the Genc Mehmet, Bogazkere and Okuzgozu local varieties were used as experimental material. The canes were obtained from a commercial vineyard in the Diyarbakir province located in southeastern Turkey. Lloyd, LRX plus series, materials testing machine was used for cutting tests. Statistically significant differences were determined between the cutting properties of grape varieties. The cutting force and cutting energy increased with increasing diameter and age of canes.
