【目的】通过研究不同钙处理对葡萄花青素合成及品质的影响,确定适宜的喷钙时期、浓度、部位,为葡萄的优质高产提供理论依据。【方法】以6 a(年)生‘美人指'为试验材料,研究了不同钙处理水平(0、1、3、5、8 g· L~(-1))、施肥方式(叶果喷施和浸果)及时期(第1次膨大期和第2次膨大期)对葡萄果实品质和花青素含量的影响。【结果】钙处理可明显提高果实的单粒质量、可溶性固形物及花青素含量,并降低果实硬度和酸度,果实品质和花青素含量随着钙质量浓度的增加而提高,在5 g· L~(-1)时效果最好,同时还发现钙处理效果在葡萄第2次膨大期优于第1次膨大期,浸果处理优于叶果喷施处理。第2次膨大期5 g· L~(...

【Objective】In order to find the proper time, concentration and method of calcium fertilization during fruit growth and development for‘Beauty finger'grape (Vitis vinifera L.), we compared the effects of different calcium treatments (different concentrations, fertilizing methods and application time) on the fruit quality, especially on anthocyanin content in grape. Some previous studies showed that spraying calcium could promote fruit quality and enhance coloration. But the proper time, concentration and fertilizing method are still unknown. ...
