摘要: 目的 我国主栽苹果品种根据亲本构成可分为富士族系、元帅族系、金冠族系和国光族系,分析不同族系果实的香气特征和遗传特性,为果品品质研究和香气育种提供参考。方法 采取固相微萃取和气相色谱质谱(SPME-GC-MS)联用技术对4个族系的50个苹果品种果实香气物质进行检测,利用变异系数(CV)和主成分分析(PCA)解析不同族系间香气物质的显著性和特征。结果 50个品种共检测出146种香气成分,酯类(38种)、醛类(29种)和醇类(19种)为主要香气物质,共占总含量的72.82%,其中酯类在数量和含量上变异系数均大于醛类和醇类。富士族系和元帅族系的总香气成分数量显著多于金冠族系(P<0.05),酯类物质数量显著多于金冠族系和国光族系(P<0.05),醛类和醇类物质的数量在不同族系间未达到显著水平。以香气值大于1为标准确定出28种特征性香气成分,其中8种成分在40个品种以上均被检测出,是苹果的典型香气成分。对28种特征性香气成分进行主成分分析,共提取8个主成分,结合香气成分的嗅感特征将50个不同品种划分为4个代表不同香型的区域,富士族系和元帅族系在4个区域均有分布,金冠族系和国光族系主要分布在青香型和淡香型区域,浓香型区域主要为元帅族系,甜香型区域主要为富士族系。不同的选育方式对金冠族系和国光族系影响更大,表现为杂交品种的相似系数、与对照共有的香气成分占比显著低于芽变品种(P<0.05);在所有族系中,芽变选育品种出现超亲现象的香气数量均多于杂交品种。结论 富士族系和元帅族系的果实风味更加丰富,富士族系、元帅族系、金冠族系和国光族系的果实风味分别表现为甜香型、浓香型、青香型和淡香型;杂交能够提高后代香气成分的含量,并增加香气构成的复杂性;芽变对后代的香气成分种类影响较小,对香气含量的影响更大,其超亲现象多于杂交后代。

Abstract:

【Objective】 Apple cultivars have been classed into Fuji-strain, Delicious-strain, Golden Delicious-strain and Ralls-strain according to their parents in China. In this study, the fruit aroma characteristics of different strains were analyzed, so as to provide the reference for studying fruit quality and aroma breeding. 【Method】 Solid-phase microextraction and gas chromatography-mass spectrometry (SPME-GC-MS) were used to detect the fruit aroma components and their content of 50 apple cultivars belonging to 4 strains. Coefficient of variation (CV) and principal component analysis (PCA) were used to compare the significance and characteristics of aroma substances among the different strains. 【Result】 A total of 146 aroma components were detected from 50 cultivars. Esters (38), aldehydes (29) and alcohols (19) played a dominant role in all aroma components, which accounted for 72.82% of the total content. CV of esters was the highest in number and content of three ruling aroma components. The number of total aroma components of Fuji-strain and Delicious-strain were significantly more than that of other strains (P<0.05). The number of Fuji-strains and Delicious-strains were meaningfully more than that of Golden Delicious-strain and Ralls-strain (P<0.05). However, the number of aldehydes and alcohols did not show a significant level among the different strains. 28 characteristic aroma components were identified from 146 aroma components according to the criterion of aroma value greater than 1, eight components of which were detected in more than 40 cultivars, and they were defined as typical aroma components of apple. The eight principal components (PCs) were extracted from 28 characteristic aromas by PCA. 50 cultivars were scattered to four regions, which represented different flavor types. According to the smell characteristics of aroma components, Fuji-strain and Delicious-strain were distributed in four regions; Golden Delicious-strain and Ralls-strain were mainly distributed in green and light flavor regions, respectively; Rich fragrance regions were primarily Delicious-strain, and sweet fragrance region were mainly Fuji-strain. Different breeding methods had stronger effects on Golden Delicious-strain and Ralls-strain, as the similarity coefficient and the proportions of aroma components shared with the controls in the hybrid cultivars were significantly lower than those of the bud sport cultivars (P<0.05). In all the strains, the number of transgressive phenomena in the bud sport cultivars was more than that in the hybrid cultivars. 【Conclusion】 The fruit flavor of Golden Delicious-strain and Ralls-strain was more abundant. Fuji-strain, Delicious-strain, Golden Delicious-strain and Ralls-strain could be classed as sweet fragrance type, rich fragrance type, green fragrance type and light fragrance type, respectively. Hybridization could increase the content of aroma components and increase the complexity of aroma composition. Bud sport breeding had less effect on aroma composition, but more effect on aroma content to the progenies, and the transgressive phenomena was more obvious than that of hybridization breeding.
