两种砧木对布鲁克斯大樱桃果实芳香成分的影响

【研究目的】为研究考特和吉塞拉作为砧木对甜樱桃果实香气成分的影响。【方法】采用顶空微萃取技术提取成熟期果实的香气成分，经气相色谱质谱联用仪进行测定分析。【结果】不鲁克斯甜樱桃的香气成分共检测到61种，主要成分为醛类、醇类和酯类。从布鲁克斯（吉塞拉）中检测出38种香气成分占总峰面积的59.66 %，相对百分含量较高的是乙醇、乙酸己酯、1-乙基－3－甲基苯、苯乙烯、1，2，3－三甲基苯。从布鲁克斯（考特）中检测出30种香气成分占总峰面积的64.74 %，相对百分含量较高的是乙醇、（E)2－己烯－1－醇、3-异丁基-6-烯-1-辛醇、乙酸己酯。【结论】吉塞拉和考特作为砧木对布鲁克斯甜樱桃果实中香气成分的影响较明显，在香气种类上吉塞拉砧木具有明显优势。（E)2－己烯－1－醇、己醛、乙酸己酯、(E)-丁酸－2－己烯酯、3-异丁基-6-烯-1-辛醇是不鲁克斯甜樱桃成熟果实的特征香气成分。

Effect of Tow Rootstock on Aroma Components on 'Brookes' Sweet Cherry

Abstract:【OBJECTIVE】In order to study the effects of rootstock on aroma components of sweet cherry.【METHOD】The headspace solid-phase micro-extraction coupled with capillarygas chromatography- massspectrometry (GC-MS) was used for the determination of volatiles in harvested ripe sweet cherry of Brookes fruit（Prunus.avium L.）.【RESULTS】A total 61 compounds were identified from the samples , alcohols, aldehydes, and esters were the major constituents. 38compounds were identified in Brookes(Jisaila root stock), representing 59.66% of the total peak area; The main contents were Alcohol , Hexyl acetate , Styrene , 1-ethyl -3- methyl –Benzene , 1,2,3-Trimethyl benzene. 30compounds were identified in Brookes(Colt root stock), representting 64.74% of the total peak area.;The main contents were Alcohol, (E)-2- Hexen-1-ol,3-t-Butyl-oct-6-en-1-ol,Hexyl acetate.【CONCLUSION】The rootstocks influence to be obvious on aroma components of sweet cherry, Jisaila root stock has the obvious superiority. (E)-2- Hexen-1-ol, Hexanal, Hexyl acetate, Butanoic acid, 2-hexenyl ester, (E), 3-t-Butyl-oct-6-en-1-ol were the characteristic aroma components of‘Brookes’sweet cherry fruit.
