摘要: 本文研究了在(25±1)℃下,气调包装和乙烯吸收剂处理对采后青梅果实叶绿素含量、内源激素IAA,GA3,ABA含量和乙烯释放量的影响及它们之间的关系。结果表明:气调包装果实叶绿素含量最高,其次是乙烯吸收剂处理的;各处理中气调包装果实的乙烯释放量始终很低,GA3含量较高,IAA和ABA含量则较低;对照果实的则相反,乙烯释放量很高,IAA和ABA含量较高,而GA3含量较低。乙烯吸收剂处理的处于二者之间。气调包装可以维持果实较高的GA3水平,降低ABA含量,保持较高的GA3/ABA值,抑制IAA和乙烯的生成,延缓梅果叶绿素的降解。

Abstract: Effects of modified atmosphere packaging (MAP) and ethylene absorbent on chlorophyll content, ethylene evolution and endogenous hormone changes in post_harvest Green Mume fruits were investigated at (25±1)℃. The results indicated that chlorophyll content in the MAP fruits was higher than that in the ethylene absorbent treated fruits while the lowest level was in the control. During storage, the MAP fruits had a steadily low ethylene evolution, higher GA3 level and lower content of IAA and ABA than those of the control. The above items in ethylene absorbent treated fruits changed between the MAP and the control. MAP might delay the senecence and degradation of chlorophyll in Green Mume fruits by means of maintaining high level of GA3, decreasing ABA content, keeping high ratio of GA3 to ABA, inhibiting the production of IAA and ethylene.
