| 摘要: |
| 在4℃±1℃,大气压力分别为101 324.7,66 661.0和13 332.2 Pa的贮藏条件下,研究了“拳杏”果实的乙烯代谢,结果表明:低压抑制了果实内源乙烯的产生,ACC和蛋氨酸含量减少,EFE活性降低,对MACC含量影响不大。低压处理14d恢复常压后,内源乙烯逐渐升高。低压处理21d恢复至常压,14d内,乙烯变化不大。低压处理未看到EFE活性“高峰”。低压对ACC含量的抑制作用是可逆的,一旦恢复至常压,含量就上升。低压贮藏有延缓果实硬度下降的作用。 |

| Abstract: |
| Ethylene metabolism in“Quanxing”apricot fruits (Armeniaca vulgaris
Lam) stored in normal (101324.7Pa) and hypobaric atmosphere (13332.2 Pa and
66661.0 Pa)at 4 ℃士l ℃ was studied.The results showed that ethylene,ACC,Met
production and activity of EFE in fruit tissues were inhibited in pypobaric atmosphere,
but the low pressure would hardly affect MACC content.Ethylene production increased
gradually under normal condition after low pressure treatment for 14 days.If samples
were stored in hypobaric atmospphere for 21 days,endogenous ethylene productionin
fruits would change very little during 14 days under normal condition.Activity of EFE
under no presssure has no climacteric“Peak”.Hypobaric inhibit effect for ACC was reversible.Content of ACC could increase immediately once fruits were exposed to normal
air.Stored fruits in hypobaric atmosphere can delay the decrease in fruit firmness |
