摘要:
对15个观赏海棠品种的8个果实品质指标（可溶性糖、可溶性固形物、有机酸含量、固酸比、糖酸比、单果重、果肉硬度、果皮硬度）进行测定，以期分析不同品种间海棠果实品质差异，为筛选海棠果实品质评价主因子和开发海棠果实应用价值提供理论和科学依据。结果表明：（1）15个海棠品种果实品质间，除果皮和果肉硬度外，均存在极显著差异；（2）8个品质指标大部分指标间存在（极）显著正（负）相关，部分指标间存在一定的相关性但不显著；（3）通过主成分分析将品质指标综合为3个因子，累积方差贡献率达到83.54%，第1主成分主要代表有机酸含量、固酸比、糖酸比和单果重，第2主成分主要代表可溶性糖含量、果肉和果皮硬度，第3主成分以可溶性固形物为主。本研究中的15个品种中，适合于食用的有‘永恒’、‘时光秀’、‘当娜’等，适合于果汁加工的有‘薄荷糖’、‘魔术’和‘印第安之夏’；宿果期、储存期较长的为‘超甜时光’。
Abstract:
To analyze the quality differences between different varieties of crabapple fruits, and provide theoretical and scientific basis for selecting main factors of crabapple fruit quality and developing the application value of crabapple fruit. Fifteen varieties of ornamental crabapple were evaluated for differences in 8 fruit quality indicators, including soluble sugar content(SS), soluble solids content(Ss), organic acid content(OC), soluble sugar/organic acid(SS/OC), soluble solid/organic acid(Ss/OC), fruit weight(FW), fresh firmness(FF) and peel firmness(PF). Result showed that (1) there occurred significant differences in 6 fruit quality indicators among 15 varities (P＜0.01); (2) A significantly positive or negative correlation was observed among some of the fruit quality indicators; (3) Three major components (PC1, PC2, PC3) with characteristic value larger than 1, whose accumulative variance contribution rate was 83.54%, were extracted by PCA. The first major component, PC1 represented OC, SS/OC, Ss/OC and FW; PC2 represented SS, FF and PF; PC3 represented Ss. In these 15 varieties studied, Malus ‘Forever ’, M. ‘Show Time’, M. ‘Donald Wyman’, etc. were suitable for consumption , M. ‘Candy mint’ and M. ‘Indian magic’ and M. ‘Indian Summer’ suitable for fruit juice processing. M. ‘Sweet Sugartyme’ possessed longer fruit retention period and storage period.
