【摘要】 为了明确蟠桃果实优质生产的果袋类型，以金霞油蟠和瑞油蟠2号2个蟠桃品种为试验材料，6月上旬分别选用外黄内黑双层袋、白色单层袋进行果实套袋处理，以不套袋处理为对照，研究了不同类型果袋对蟠桃果实外观品质和内在品质的影响。结果表明：与未套袋的对照相比，2个蟠桃品种果实套袋后单果重和可食率明显增大，成熟期果面黄色度增加、红色度降低，果面亮度和光洁度有效提高，果皮擦伤度和果实裂果率明显降低，带皮硬度、去皮硬度和可溶性固形物含量降低不显著，其中套外黄内黑双层袋的效果优于套白色单层袋。外黄内黑双层袋对提高蟠桃果实外观品质和内在品质的效果优于白色单层袋，研究结果可为今后生产实践中提高蟠桃果实品质，尤其是解决蟠桃裂果问题提供理论参考。更多还原

【Abstract】 In order to clarify the types of fruit bags for high-quality production of flat peach,two flat peach varieties Jinxiayoupan and Ruiyoupan 2 were used as experimental materials,the outer yellow and inner black double-layer bags and white single-layer bags were selected for fruit bagging treatment in early June. The effects of different types of fruit bags on the appearance and internal qualities of flat peach fruits were studied,with no bagging treatment as the control. The results showed that compared with the control without bagging,the single fruit weight and edible rate of the two flat peach varieties increased significantly after bagging,and the b* of peel increased and the a*of peel decreased during the ripening period. The brightness and smoothness of the fruit surface were effectively improved,and the degree of skin abrasion and fruit cracking significantly reduced.However,the hardness of fruit,the hardness of flesh,and the content of soluble solids were not significantly reduced. Among them,the effect of bagging the outer yellow and inner black double-layer bags was better than that of bagging the white single-layer bags. The effect of outer yellow and inner black double-layer bag on improving the appearance and internal qualities of flat peach fruit is better than that of white single-layer bag.The research results can provide theoretical reference for improving the quality of flat peach fruit, especially solving the problem of cracking in future production practice.更多还原
