摘　　要：为探究不同负载量水平对阳光玫瑰葡萄果实综合品质的影响,本研究通过对葡萄果实进行果粒疏除来调控负载量水平,同时对果实中的糖、酸、酚类物质含量,抗氧化活性及经济效益进行了评估。结果表明,低负载量水平下的葡萄果实平均粒重显著增加,葡萄糖和果糖含量显著增加,酒石酸和苹果酸含量显著下降,致使果实糖酸比显著增加(P<0.05)。同时酚类物质含量显著上升,果实的抗氧化能力也显著优于其它处理组(P<0.05)。由于低负载量水平下的葡萄果实综合品质优异,使其具有更高的经济收益。因此,通过精确控制葡萄产量可以获得更好的葡萄品质。To investigate the effects of different crop loads on the overall quality of'Shine Muscat',this study was conducted to regulate the crop loads by berry thinning and to evaluate the sugar,acid and phenolic contents,antioxidant activity and economic benefits of the berries.The results showed that the average berry weight at low crop loads increased significantly,glucose and fructose contents increased significantly,and tartaric and malic acid contents decreased significantly,leading to a significant increase in the sugar-acid ratio of the berries(P<0.05).The phenolic content at low crop loads also increased significantly and the antioxidant capacity of the berries was significantly better than the other treatment groups(P<0.05).The excellent overall quality of berries at low crop loads made them more economically profitable.Thus,better grape quality could be achieved by precisely controlling the berry crop load.
