摘要: 以百蜜系列南瓜品种(系)为试验材料,在16 ~ 18 ℃下架式贮藏,设置10、20、30、40、50、60 d共6个贮藏时间,测定果实可溶性固形物含量、淀粉含量、可溶性糖含量、β-胡萝卜素含量、维生素C含量、丙二醛含量、呼吸速率、失重率和果皮硬度等营养品质及生理指标,对百蜜系列南瓜品种(系)果实采后的耐贮性和品质变化进行分析,并结合主成分分析、相关性分析、聚类分析进行耐贮性综合评价,以期筛选出耐贮性强的南瓜品种(系)。结果表明,在不同贮藏期,百蜜5号淀粉含量最高,均值为1.39 mg/g;百蜜3号呼吸速率、可溶性固形物含量和β-胡萝卜素含量最高,均值分别为34.60 mg(/kg·h)、10.80%和25.20 μg/g;百蜜10号果皮硬度最高,均值为25.17 N;百蜜2号失重率最高,均值为8.95%。主成分分析结果表明,供试南瓜品种(系)的贮藏指标可以用5个主成分来表示,方差累计贡献率达91.922%。进一步采用隶属函数法和聚类分析对百蜜系列南瓜品种(系)进行耐贮性综合评价,结果表明,百蜜10号可作为耐贮藏品种进行推广种植,百蜜2号的耐贮性较差,适合短途运输或就地销售。

Abstract: The Baimi series of pumpkin varieties(lines)were used as experimental materials,and stored at 16—18℃ for 6 storage periods(10,20,30,40,50,60 d). The nutritional quality and physiological indexes such as soluble solids content,starch content,soluble sugar content,β‐carotene content,vitamin C content,malondialdehyde content,respiration rate,weight loss rate and peel hardness were measured.The storage tolerance and quality changes of Baimi series of pumpkin varieties(lines)were analyzed,and the storage tolerance was comprehensively evaluated by principal component analysis,correlation analysis and cluster analysis,in order to screen out pumpkin varieties(lines)with strong storability.The results showed that the starch content of Baimi 5 was the highest in different storage periods,with an average of 1.39 mg/g.The highest respiration rate,soluble solids content and β‐carotene content of Baimi 3 were 34.60 mg(/kg·h),10.80% and 25.20 μg/g,respectively. The peel hardness of Baimi 10 was the highest,with an average of 25.17 N.The weight loss rate of Baimi 2 was the highest,with an average of 8.95%.The results of principal component analysis showed that the storage indexes of the tested pumpkin varieties(lines) could be expressed by five principal components,and the cumulative contribution rate of variance was 91.922%. Furthermore,the storage tolerance of Baimi series pumpkin varieties(lines)was comprehensively evaluated by membership function method and cluster analysis.The results showed that Baimi 10 could be used as a storage‐tolerant variety for planting and promotion,while Baimi 2 had poor storability and was suitable for short‐distance transportation or local sales.
