摘要
为进一步探讨气调贮藏对冬枣贮藏质量的影响,研究了冬枣果实在低温(-1～-2℃)条件下,8个不同体积分数的气体成分(15%O2+0%CO2、10%O2+0%CO2、5%O2+0%CO2、2%O2+0%CO2、2%O2+2%CO2、2%O2+4%CO2、2%O2+8%CO2、2%O2+10%CO2)和1个对照(21%O2+0%CO2)处理对冬枣果实呼吸、组织相对电导率、叶绿素含量及果皮色泽的影响。结果表明:适当的低O2可降低枣果的呼吸强度、减慢组织相对电导率的升高、延缓枣果叶绿素的降解、延迟果皮转红;而贮藏环境中的CO2则会促进果实呼吸、导致组织相对电导率升高、促进叶绿素的降解和果皮的转红。2%O2+0%CO2的气体条件对冬枣贮藏最为有利。
In order to further explore the effects of controlled atmosphere（CA） on Dongzao jujube fruit quality during storage,the effects of 8 different treatments with gas compositions （15%O2＋0%CO2,10%02＋0%C02,5%02＋0%C02,2%02＋0% CO2,2%O2＋2%CO2,2%O2＋4%CO2,2%O2＋8%CO2,2%O2＋10%CO2） and one CK （21%O2＋0%CO2） on respiration intensity, relative electrical conductivity, contents of chlorophyll and fruit skin color of Dongzao jujube cuhivar were studied under the condition of low temperature（-1 to -2 ℃ ）. The results showed that appropriate low concentration of O2 could result in the reduction of Dongzao jujube＇ s respiratory intensity, slow down the increase of pulp＇ s relative electrical conductivity, delay the degradation of chlorophyll in fruit and retard fruit skin changing to red; but CO2 could accelerate fruit respiration, causing increase of pulp＇ s relative electrical conductivity, promoting degradation of chlorophyll and fruit skin changing to red. The results indicated that the CA condition of 2%O2＋0%CO2was the best for storage of Dongzao jujube fruit.
