摘　　要：【目的】探讨不同颜色果袋引起的光环境差异对新郁葡萄着色及品质的影响。【方法】以7年生新郁葡萄为试验材料,采用5种颜色果袋(白袋、红袋、黄袋、蓝袋、绿袋)进行果实套袋处理,以不套袋为对照,测定不同果袋内的透射光谱和采收期葡萄品质指标及果皮花色苷组分。【结果】与对照相比,不同颜色果袋均不同程度降低了果际总辐射和果实可溶性固形物及果皮花色苷含量,绿袋提高了可滴定酸含量,降低了果粒质量;白袋降低了3’-羟基取代类花色苷比例,提高了3’,5’-羟基取代类花色苷比例,而红袋、黄袋、蓝袋和绿袋则效果相反;白袋、红袋和黄袋提高了总修饰类花色苷比例,而绿袋则降低了总修饰类花色苷比例。红袋的葡萄果皮花色苷含量为1418.67mg·kg-1,葡萄果实色泽指数(colorindexofgrape,CIRG)为4.80,颜色为红色,着色最好。相关分析表明,橙光和红光辐射强度与3’-羟基取代类花色苷含量呈极显著正相关。【结论】西北干旱区采用红色果袋套袋能够改善新郁葡萄着色,提高综合品质。【Objective】The table grape variety Xinyu was bred from a hybrid of a single Red Globe plant E-42-6 as the female parent and Rizamat as the male parent.Xinyu berries are oval in shape and have a dark red/violet skin,a mean weight of 11.6 g,a slightly crisp texture,a sour-sweet flavour,a solu-ble solid content of 16%-19%,and good storage,transportation and adaptability characteristics.During the fruit coloration stage,intense light can result in excessively dark coloration and affect appearance quality and commodity.Fruit bagging is effective to regulate light environment during the growth and development of grapes.Therefore,the objective of this study was to evaluate the effects of different bags on fruit-zone light environment,berry quality and anthocyanin components.The results will pro-vide reference for selection of fruit bags for production of high quality berries of Xinyu grape in the ar-id area of Northwest China.【Methods】Xinyu grapevines were used as test materials,five color fruit bags(white bags,red bags,yellow bags,blue bags and green bags)were used for fruit bagging treat-ment,and no bagging was used as the control(CK).The transmission spectra of different color fruit bags were analyzed with UniSpec-SC single-channel portable spectrometer,and the berry quality index-es and anthocyanin components in the peel were measured during berry ripening.【Results】The total ra-diation in the bags decreased at different degrees compared with the control.The white bag had the highest total radiation and transmittance,followed by the red bag,the yellow bag,the blue bag,and the green bag.The light radiation intensity of each wavelength in the different bags was reduced compared with that in the control,and the red light and infrared light had the largest reduction,with more than 50%.The proportion of red light significantly decreased in the blue bag and the green bag.The berry mass in the treatment with green bag significantly decreased by 15.59%,and berry mass in the other treatments had no significant dif
