Abstract

Floral scent holds considerable ecological and industrial significance. Frequently cultivated crabapples are scentless and little research has been done on their aromatic properties, which has impeded the ecological and industrial exploration of fragrant crabapple cultivars. M. 'Lollipop', M. 'Hydrangea' and M. 'Prairie Rose' crabapple cultivars, known for their strong floral scent, high resistance and consistent flowering period, were selected to investigate their volatile composition, emission patterns, and floral scent emission localization. Gas chromatography-mass spectrometry analysis identified four primary groups of floral compounds in the three ornamental crabapple cultivars: aliphatic compounds (34 types, 47.88 %), benzenoids/phenylpropanoids (18 types, 25.35 %), terpenes (12 types, 16.90 %), and miscellaneous compounds (7 types, 9.86 %). M. 'Prairie Rose' exhibited the highest diversity of unique compounds, predominantly terpenes. Floral scent emission peaked during the flowering stage (S3) across three crabapples. Dissimilarity coefficient analysis revealed that petals significantly contributed to the overall floral scent in M. 'Lollipop' and M. 'Hydrangea'. Scanning electron microscopy demonstrated that the entire petal functions as a large aromatic gland in three crabapples. These findings provide valuable insights for breeding and industrial applications of fragrant ornamental crabapples.

海棠花香味的挥发性成分、释放模式及定位

花香具有重要的生态和工业意义。通常栽培的海棠是无香的，对其芳香特性的研究很少，这阻碍了海棠香型品种的生态化和产业化开发。M。“棒棒糖”,M。绣球花和M。以“草原玫瑰”海棠品种为研究对象，对其香气浓烈、抗性高、花期一致等特点进行了研究。气相色谱-质谱联用分析鉴定了3个观赏海棠品种花类化合物的4个主要类群：脂肪类化合物34种，占47.88%；类苯/苯丙类化合物18种，占25.35%；萜类化合物12种，占16.90%；杂类化合物7种，占9.86%。M。“草原玫瑰”的独特化合物多样性最高，主要是萜烯。3种海棠花香在开花期（S3）达到峰值。差异系数分析表明，花瓣对整个花香的贡献显著。“棒棒糖”和M。“绣球花”。扫描电镜显示，三个海棠花的整个花瓣具有大的芳香腺的功能。这些发现为观赏香海棠的选育和工业应用提供了有价值的见解。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
