Grape crop control is commonly managed by balanced winter pruning. However, balanced winter pruning alone may not sufficiently control the crop level of grapevines. Recently, there has been growing interest in the use of various yield regulation methods from different canopy management practices. There is considerable interest in enhancing the quality characteristics of grapes by means of leaf removal before or at bloom time in grape-growing countries all around the world. Similar to early leaf removal practices, bunch tipping is also performed in vineyards to achieve premium-quality table grapes. Furthermore, reflective mulches applications are also used for improving sunlight distribution of inner side of grapevine canopy, leading to an enhanced grape skin color. In the current study, influences of applications of early leaf removal (ELR), reflective mulch (RM), bunch tipping (BT), and the combinations of ELR+RM, ELR+BT, RM+BT, and BT+ELR+RM on the physical and biochemical attributes of cv. Trakya Ilkeren were investigated. The findings show that the best results were obtained from applications of ELR+RM and BT+ELR+RM.

葡萄作物控制通常通过平衡的冬季修剪来管理。然而，单独的平衡冬季修剪可能不足以控制葡萄藤的作物水平。最近，人们对使用来自不同冠层管理实践的各种产量调节方法越来越感兴趣。在世界各地的葡萄种植国，人们对通过在开花前或开花时去除叶子来提高葡萄的质量特性非常感兴趣。与早期的叶子去除实践类似，葡萄园也进行了葡萄串倾倒以获得优质鲜食葡萄。此外，反射覆盖物的应用还用于改善葡萄树冠内侧的阳光分布，从而增强葡萄皮的颜色。在目前的研究中，早期除叶 (ELR) 应用的影响，反射覆盖物 (RM)、束倾倒 (BT) 以及 ELR+RM、ELR+BT、RM+BT 和 BT+ELR+RM 的组合对 cv. 的物理和生化属性的影响。Trakya Ilkeren 进行了调查。结果表明，ELR+RM 和 BT+ELR+RM 的应用效果最好。
