摘要:

以‘红星’苹果为试材,研究α-法尼烯和共轭三烯的合成和转化部位,试验表明,α-法尼烯在果实表皮角质层中大量合成,分别向外蜡质层和向内皮下细胞和果肉薄壁细胞双向转移,在果实表皮蜡质层或角质层中与氧接触,氧化生成共轭三烯和其它氧化产物;虎皮病发生、α-法尼烯与共轭三烯的含量都与贮藏温度呈显著的负相关。

Abstract:

With ‘Red Delicious’apple as a material, the specific position of α-farnesene formation in the apple were identified,respectively,to provide experimental evidence for the proposal of the mechanism of apple superficial scald. Results showed that α-farnesene was formed in large amount in horny layer,and not only difused outward to wax layer but also inward to hypodermic and pulp cell. Once it met oxygen in horny and wax layer. α-farnesene was oxidized to conjugated trienes and other products.The degree of scald development and the both contents of α-farnesene and conjiugated trienes were inversely propotional to store temperature.

Key words: Apple, Superficial scald, α-farnesene, Conjugated trienes, Storage, Temperature
