    摘要:

    通过杂交育种进行花香特征改良是花香育种重要方式。本研究采用顶空固相微萃取和气相色谱-质谱联用技术(HS-SPME-GC-MS)对满庭芳华及其父母本盛开期花瓣挥发性物质进行了测定和比较分析。结果表明:满庭芳华及其父本弯刺蔷薇、母本伊丽莎白女王盛开期花瓣中分别检测到25种、36种及22种挥发性有机物,包括醇类、萜烯类、酯类、烃类、醚类、醛类、酮类和酸类8类,共计59种组分。满庭芳华与弯刺蔷薇存在10种共有成分,与伊丽莎白女王存在13种共有成分,8种特有成分,其香气成分种类与母本更为相似。满庭芳华花香成分总释放量为579.70 ng/g,低于父本(13939.42 ng/g)、母本(1157.10 ng/g),其中,萜类和苯类/苯丙素类化合物含量低于父母本,但其倍半萜类物质的种类和含量高于父母本,脂肪酸及其衍生物类总含量介于父母本之间;主成分分析及相对含量表明,β-荜澄茄油烯、β-杜松烯、β-石竹烯等为主要影响满庭芳华香气的挥发性组分。本研究可以为蔷薇属植物花香代谢遗传改良提供参考,具有重要的理论价值和实践意义。

    Abstract:

    Improving the fragrance characteristics through hybridization is an important way of fragrant flower breeding. In this study, Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry (HS-SPME-GC-MS) was employed to determine the volatile organic compounds (VOCs) in blooming petals of the rose variety Mantingfanghua and its parents. Comparison analysis of VOCs showed that 25, 36 and 22 VOCs were identified in the blooming petals of Mantingfanghua, its paternal species Rosa beggeriana Schrenk and maternal variety Queen Elizabeth, respectively. The totally identified 59 components can be sorted to 8 major compounds based on their chemical structures, including alcohols, terpenes, esters, hydrocarbons, ethers, aldehydes, ketones and acids. Mantingfanghua has 10 components in common with Rosa beggeriana Schrenk, while 13 in common with Queen Elizabeth; Mantingfanghua has the VOCs composition in higher similarity to its maternal variety. The total VOCs content in Mantingfanghua was 579.70 ng/g, which was lower than that in its paternal species (13939.42 ng/g) and its maternal variety (1157.10 ng/g). The contents of terpenoids and benzenoids/phenylpropanoids were lower in Mantingfanghua than those in its parents; in opposite, the contents of sesquiterpenoids in Mantingfanghua were higher than those in its parents. Meanwhile, the content of fatty acid derivatives in Mantingfanghua fell in between those in their parents. Principal component analysis showed that the β-Cubebene, β-Cadinene, β-Caryophyllene were the main VOCs that may affect the fragrance from Mantingfanghua. This study provides insights for the genetic improvement of rose floral fragrance metabolism, which has important value for both theoretical and practical purpose.
