摘　　要：以蒙阴地区的“映霜红”“青州蜜”“金秋红蜜”“世纪桃王”“黄金脆”“晴朗”“瑞蟠101”共7个桃品种为试材,采用多种基本品质测定和相关性分析、主成分分析等方法,研究了不同品种晚熟桃的品质及矿质元素特性,筛选出综合品质较优的晚熟桃品种,以期为晚熟桃的品种推广提供参考依据。结果表明:不同矿质元素的含量在不同品种间存在显著性差异,其中Na、Cr元素含量的变异系数最高,分别为157.16%、121.03%。果实的品质指标与矿质元素含量存在相关性,单果质量与横径、纵径、Na元素含量呈极显著正相关,糖度与V元素含量呈极显著相关,与Al、Co元素含量呈显著正相关,水分与Sn元素含量呈极显著正相关,与Be元素含量呈极显著负相关。经主成分分析将28个指标综合成5个主成分因子,Be、Cr、Fe、Co、Ni、V元素和果形指数对第1主成分贡献最大,P、S、K对第2主成分贡献最大。Be、Cr等元素对桃的品质影响较大。经综合评价,7个品种的得分排名为“瑞蟠101”>“晴朗”>“世纪桃王”>“金秋红蜜”>“青州蜜”>“黄金脆”>“映霜红”。Seven varieties of late-maturing peaches in Mengyin area were used as experimental materials,including‘Yingshuanghong’‘Qingzhoumi’‘Jinqiuhongmi’‘Shijitaowang’‘Huangjincui’‘Qinglang’and‘Ruipan101’.A variety of methods,including multiple basic quality determinations,correlation analysis and principal component analysis,were employed to investigate the quality and mineral element characteristics of different late-maturing peach varieties,with the aim of screening out those with superior comprehensive quality.The results showed that there were significant differences in the contents of different mineral elements among different varieties,among which the coefficients of variation of Na and Cr elements were the highest,which were 157.16%and 121.03%,respectively.The quality indexes of fruit were correlated with the contents of mineral elements.The single fruit weight was extremely significantly positively correlated with the transverse diameter,longitudinal diameter and Na element content,the sugar content was extremely significantly positively correlated with V element content,and significantly positively correlated with Al and Co element content,the moisture content was extremely significantly positively correlated with Sn element content,and extremely significantly negatively correlated with Be element content.The 28 indexes were synthesized into 5 principal component factors by principal component analysis.Be,Cr,Fe,Co,Ni,V elements and fruit shape index contributed the most to the first principal component,and P,S,K contributed the most to the second principal component.Elements such as Be and Cr have a significant impact on the quality of peaches.After comprehensive evaluation,the score ranking of seven varieties is‘Ruipan 101’>‘Qinglang’>‘Shijitaowang’>‘Jinqiuhongmi’>‘Qingzhoumi’>‘Huangjincui’>‘Yingshuanghong’.This study provides a reference for the promotion of late-maturing peach varieties.
