两种施肥处理对红富士苹果香气成分的影响

Two Fertilizer Treatments on the Aroma Components in Fuji Apples

用顶空固相微萃取和气相色谱质谱联用技术对2种不同施肥处理的洛川红富士苹果的香气成分进行了分析,共鉴定出了35种化学成分,其中酯类20种,主要有乙酸2-甲基丁酯、乙酸丁酯、2-甲基丁醇、乙酸己酯等;醇类6种,主要有1-丁醇和1-已醇等;醛类4种,主要包括正己醛和2-已烯醛。结果表明:分期施肥处理的苹果香气成分的含量和丰富度明显高于一次性施肥处理的苹果。

Aroma components of two. different fertilizer treatments with Fuji apples analyzed by gas chromatography-mass spectrometry. A total of 35-components were identified, including 20-esters, 1-Butanol, 2-methyl-, acetate, Acetic acid, butyl ester, 1-Butanol, 2-methyl-, Acetic acid, hexyl ester were the chief components; 6-alcohols, 1-Butanol. 1- Hexanol were the chief components;4-aldehydes, Hexanal, 2-Hexenal were the chief components. The oresult showed that the apple aroma components and richness in split application was higher than the single fertilization.
