Grape (Vitis vinifera L.) is considered as one of the most important commercial fruit crops in Turkey. Wine quality is affected by cultural practices. The main purpose of this study was to evaluate the effects of crop load level and different summer pruning applications on the wine quality of ‘Mevlana’ (Vitis vinifera L.). The study was carried out on a 12-year-old own-rooted ‘Mevlana’ vineyard, which was established as a rational pergola in Manisa. Two different crop load levels (55 clusters/vine and 110 clusters/vine) and four different applications were adapted to these crop loads. Applications are, I: removal of 1/3 cluster (the ends of the bunch were cut with scissors at berry state; 4 mm of berry), II: girdling (girdling was the removal of a ring of phloem around the trunk, while scoring was a simple metal wire (3 mm diameter) at berry state; 4 mm of berry, thirty-five days after application, the wires were removed), III: removal of 1/3 cluster (the ends of the bunch were cut with scissors at berry state; 4 mm of berry) and girdling (thirty-five days after girdling, the wires were removed), IV: control (no application). Yield (kg/vine), and other quality characteristics were analyzed. The best results were obtained from girdling application (27.99, 28.59) in cluster length (cm) and obtained from application of 55TII and 110TII (20.34, 20.38) in berry width (mm) and were obtained from applications of 110TII (84.80 number/vine) in number of marketable cluster and application of 55TII and 110TII (47.46, 47.02) in L^* level. The conclusion that can be drawn from the results of this study is that 55TII and 110TII applications led to enhancements in the berry growth and biochemical properties of cv. ‘Mevlana’ to rational pergola trailing system.

葡萄（Vitis vinifera  L.）被认为是土耳其最重要的商业水果作物之一。葡萄酒质量受文化习惯的影响。这项研究的主要目的是评估农作物负荷水平和不同夏季修剪方式对'Mevlana'（Vitis vinifera）葡萄酒品质的影响。 L.）。这项研究是在一个拥有12年历史的自有根基的“ Mevlana”葡萄园中进行的，该葡萄园是在Manisa建立的合理凉棚。两种不同的农作物负荷水平（55个/葡萄藤和110个集群/葡萄）和四种不同的应用适应了这些农作物的负荷。应用如下：I：去除1/3簇（用剪刀在浆果状态下切成束的末端；浆果4 mm），II：环剥（环剥是除去树干周围的韧皮部环，同时得分）是一根简单的金属线（直径3毫米），处于浆果状态； 4毫米的浆果，在施用后三十五天，将金属线去除），III：去除1/3簇（用剪刀剪去束的末端）在浆果状态； 4mm浆果）和环剥（环剥后的三十五天，将金属丝去除），IV：对照（不施用）。产量（千克/藤），分析了其他质量特征。最好的结果是从簇长（cm）的环剥应用（27.99，28.59）获得的，从浆果宽度（mm）的55TII和110TII（20.34，20.38）的应用获得的，以及从110TII（84.80的数字/葡萄）的应用获得的最佳结果。 ）在55TII和110TII（47.46，47.02）在L中的可销售集群的数量和应用^*级。可以从这项研究的结果得出的结论是55TII和110TII的应用导致了cv的浆果生长和生化特性的增强。“ Mevlana”到合理的凉棚拖曳系统。
