在印度丰富的芒果种质资源中，阿方索是一个非常受欢迎和出口的芒果品种。芒果是一种跃变型果实，乙烯对芒果的成熟起着重要作用。为了更深入地了解跃变型前乙烯处理对阿方索芒果挥发物谱的影响，对乙烯处理和对照阿方索芒果果肉和果皮的6个成熟阶段的26种挥发物进行了追踪。该研究揭示了加速成熟方面的成熟特定的化合物，内酯和mesifuran，乙烯处理后的早期出现。虽然内酯的水平保持不受影响，但在乙烯处理后，甲西呋喃水平大大增加。果皮中萜烯含量高，而果肉中内酯含量高于果皮。这项工作指向参与乙烯作为一种天然激素在生物合成的内酯和呋喃酮在自然成熟的水果，而在成熟过程中的萜烯水平的增加似乎是独立的乙烯。(C)2012爱思唯尔有限公司保留所有权利。
Alphonso is a highly favoured and exported mango cultivar among the vast mango germplasm of India. Being a climacteric fruit, ethylene plays an important role in ripening of mango. For deeper understanding of effect of pre-climacteric ethylene treatment on volatile profiles of Alphonso mango, 26 volatiles were tracked through six ripening stages of pulp and skin of ethylene-treated and control Alphonso fruits. The study revealed accelerated ripening in terms of early appearance of ripening-specific compounds, lactones and mesifuran, upon ethylene treatment. While the level of lactones remained unaffected, the mesifuran level vastly increased upon ethylene treatment. Skin showed high terpene content while pulp had higher amount of lactones compared to skin. This work points towards involvement of ethylene as a natural hormone in the biosynthesis of lactones and furanones in naturally ripened fruits; whereas, an increase in the terpene level during ripening appears to be independent of ethylene.
