研究了低氧（2 kPa）气调贮藏对金冠苹果（GD）贮藏期间香气物质合成的影响。结果表明，酯含量以皮组织最高，其次是肉2和肉1。2 kPa O2贮藏导致GD苹果挥发性酯和醇类物质的释放量减少，而醛类物质的释放量增加。值得注意的是，与皮肤组织相比，2 kPa O2贮藏GD苹果的果肉组织具有相对较高的酯的生物合成的恢复能力，但其货架期的醇合成的恢复能力较低。这种影响与MdLOX1a和MdAAT（MdAAT 1和MdAAT 2）转录物水平的增加以及果肉组织中MdHPL转录物水平的降低有关。此外，乙烯对低氧条件下果实香气物质合成的调控网络也十分复杂。总体而言，低氧贮藏后GD苹果香气生物合成具有组织特异性恢复能力。
The impact of low-oxygen (2 kPa) controlled atmosphere storage on the recovery of aroma biosynthesis in ‘Golden Delicious’ (GD) apple tissues during their subsequent shelf life was investigated. The results showed that the highest ester content was found in skin tissue, followed by Flesh 2 and Flesh 1. The 2 kPa O2 storage of GD apples resulted in a decrease in the emission of volatile esters and alcohols, but an increase in aldehyde emission. Notably, compared with skin tissue, the flesh tissue of 2 kPa O2-stored GD apples had a relatively high recovery capacity of ester biosynthesis but a low recovery capacity of alcohol synthesis for its shelf life. The impact was associated with increased levels in the MdLOX1a and MdAATs (MdAAT1 and MdAAT2) transcripts, as well as a decreased level in the MdHPL transcript in the flesh tissue. In addition, a complex regulatory network of ethylene on fruit aroma biosynthesis in response to low-oxygen conditions was also indicated. Collectively, there was a tissue-specific recovery capability of aroma biosynthesis in GD apples after low-oxygen storage.
