摘要: 为了了解红富士苹果花散粉后的挥发性物质,探讨其挥发性物质和传粉昆虫的关系,为苹果蜜蜂授粉提供思路。笔者采用固相微萃取和气相色谱-质谱联用技术,测定红富士苹果花散粉后的挥发性物质,进行定性分析;按面积归一化法进行定量分析。结果表明:从红富士苹果鲜花中共检测鉴定出31种挥发性成分,有醇类4种(76.05%)、芳香烃类4种(5.36%)、腈类1种(橙花腈,4.6%)、烷烃类10种(4.54%)、酯类7种(3.86%)、烯类3种(3.71%)、醛类1种(壬醛,1.67%)、酸类1种(月桂酸,0.21%)组成。醇类中以苯甲醇含量高,为49.74%;其次芳樟醇17.9%,(Z)-3-己烯-1-醇7.82%,雪松醇0.59%。烯类有罗勒烯、石竹烯和法呢烯,罗勒烯含量最高为2.69%。苯甲醇、(Z)-顺-3-己烯-1-醇、芳樟醇、橙花腈为苹果鲜花挥发物的主体成分。

Abstract: The paper aims to discuss the relationship between volatile components and pollination insects by learning about volatile components of Fuji apple flowers, and to provide a research basis for bee pollination on apple. Headspace solid-phase microextraction (HS-SPME) combined with gas chromatographymass spectrometry (GC-MS) was applied to measure and analyze the volatile components of live flowers after anther dehiscence during apple blossom; and a quantitative analysis was conducted with the method of area normalization. The results showed that: 31 kinds of volatile components were identified from Fuji apple flowers, including 4 kinds of alcohols (76.05%), 4 kinds of aromatic hydrocarbons (5.36%), 1 kind of nitrile (neryl nitrile, 4.6%), 10 kinds of alkanes (4.54%), 7 kinds of esters (3.86%), 3 kinds of terpene (3.71%), 1 kind of aldehydes (nonanal, 1.67% ), 1 kinds of acids (Dodecanoic acid, 0.21% ). Benzyl alcohol had the highest content in alcohols, accounted for 49.74%, followed by linalool (17.9%), (Z )-3-Hexen-1-ol (7.82%) and cedrol (0.59%). Terpene components included 1,3,6- Octatriene, 3,7- dimethyl- ,(Z ), caryophyllene and alpha.- farnesene, and the content of 1,3,6-Octatriene, 3,7-dimethyl-,(Z ) (2.69%) was the highest in terpene. Benzyl alcohol, (Z )-cis-3-hexene-1-alcohol, linalool, neryl nitrile were the main volatile components in Fuji apple flowers.
