Bioactive compounds and electrochemical characteristics are remarkable quality components for wine grapes and quality characteristics of grape are influenced by various factors such as grape cultivar, environmental and viticultural practices in a vineyard. There has recently been growing interest in improvement of wine grape quality characteristics by means of basal leaf removal (BLR) and reflective mulch (RM) practices. In current study, treatments of BLR, RM and BLR + RM were performed at two different phenological stages of grapevine, including pea size period (PSP) and vérasion period (VP). At the end of research, study results revealed that different treatment timings of basal leaf removal and reflective mulch had crucial roles on increasing of wine grape quality. Consequently, BLR-PSP + RM-PSP treatment especially led to significant enhancements in biochemical characteristics of cv. Cabernet Sauvignon like phenolic compounds, anthocyanins and electrochemical characteristics.

生物活性化合物和电化学特性是酿酒葡萄的重要品质成分，葡萄的品质特性受葡萄品种、环境和葡萄园葡萄栽培实践等多种因素的影响。最近，人们越来越关注通过去除基叶 (BLR) 和反光覆盖 (RM) 实践来改善酿酒葡萄的品质特性。在目前的研究中，BLR、RM 和 BLR + RM 的处理在葡萄的两个不同物候阶段进行，包括豌豆大小期 (PSP) 和葡萄成熟期 (VP)。研究结束时，研究结果表明，去除基叶和反光覆盖的不同处理时间对提高酿酒葡萄质量具有重要作用。最后，BLR-PSP + RM-PSP 处理尤其导致 cv. 生化特性的显着增强。赤霞珠像酚类化合物、花青素和电化学特性。
