摘　　要：为综合评价北冰红葡萄品种特性,以3个采样点(阳坡、阴坡、半阴半阳坡)5个不同采收期(T1、T2、T3、T4、T5)的北冰红葡萄为研究对象,测定单粒果重、可溶性固形物等指标,以福林肖卡法重点考察了果实不同部位(果皮和果籽)总酚含量的变化,旨在研究不同采收期北冰红葡萄果实酚类物质的积累规律.结果表明,3个采样点在T5时期的北冰红葡萄果实中总酚含量分别为88.48 mg/g、88.06 mg/g、78.34 mg/g,均显著(p<0.05)高于其他时期的总酚含量,且单粒果重和可溶性固形物含量随采收期的延长而增长,确定了北冰红葡萄的最适采收期为T5.该研究结果将为实际生产中进一步调控酿酒葡萄总酚物质积累和果实品质提供一定的理论依据.In order to comprehensively evaluate the characteristics of Beibinghong grape,taking Beibing-hong grape(Vitis amurensis Rupr)which came from three sample points(sunny slope,shady slope,semi-sunny and semi-shady slope)in five different periods(T1,T2,T3,T4,T5)as the research object,the total phenol content of different parts of fruit in different harvesting periods was determined by Folin-Ciocalteau method in order to reveal the change of total phenol content,and the weight of single fruit and soluble solid content were also measured.The results showed that the maximum total phenol content of Beibinghong grape,in different slope T5 periods was 88.48 mg/g,88.06 mg/g and 78.34 mg/g respec-tively,significantly higher than that in other periods.The individual grain weight and soluble solid content increased with the extension of harvesting period.Therefore,it is determined that the optimum harvest date of Beibinghong grape,is T5.The study will provide certain theoretical basis for further control of total phenolic substances accumulation and fruit quality of grape wine during actual production.
