据《Scientia Horticulturae》的报道(2012年7月),来自意大利佩鲁贾大学的研究人员于2008—2009年研究了葡萄花前摘叶对合理控制葡萄产量以及提高葡萄和葡萄酒品质的效果。试验以意大利高产红色酿酒葡萄品种Ciliegiolo为材料。开花前长期控制水肥,使冠层叶片减少75%~80%,导致着果率降低,浆果重量减小, According to the report of “Scientia Horticulturae” (July 2012), researchers from the University of Perugia, Italy, in 2008-2009 studied the effect of pre-harvest leaves on the rational control of grape yield and grape and wine quality. The experiment was based on Ciliegiolo, a high-yielding red wine grape variety from Italy. Long-term control before the flowering of water and fertilizer, so that canopy leaves reduced by 75% to 80%, resulting in lower fruit rate, berry weight reduction,
