| 摘 要： | 以新红星苹果为试材 ,探讨苹果低氧气调新组合贮后一段时间内不发生虎皮病的生理机制。结果表明 ,气调新组合处理 4个月的苹果 ,贮藏效果好 ,果皮α -法尼烯和共轭三烯含量较低 ,在此后 2个月的冷藏期中 ,果皮α -法尼烯和共轭三烯含量较高 ,但未发现虎皮病果。气调新组合处理的苹果在贮后一段时间不发生虎皮病 ,与气调处理期间其果皮α -法尼烯和共轭三烯的形成受到显著抑制、共轭三烯的形成高峰延缓至贮后一段时间出现有关

Physiological basis of post-storage effects of a special low-oxygen CA combination for apples |
| |
| Abstract: | The physiological basis of post-storage effects of low-oxygen CA treatment which can control superficial scald of apples for a longer period was studied, using Starkrimson apple as experimental material The results showed that the α-farnesene and conjugated trienes contents of special CA-treated apples were significantly low,its fruit firmness, soluble solids and peel chlorophyll levels were almost the same as those of standard CA,equal to or higher than those of cold storage in air after 4 months When special CA-treated apples were stored in cold air,α-farnesene and conjugated trienes contents of special CA-treated apples were high,but apples were still scald-free during 2 months of post-storage periods The formations of α-farnesene and conjugated trienes were significantly inhibited by special CA treatment during CA storage and the accumulation peak of conjugated trienes was delayed to appear after a longer post-storage period,this may be the reason why no scald fruit was observed among special CA-treated apples during a longer post-storage period |
