摘要: 本文研究了在25℃下,气调包装和乙烯吸收剂处理对青梅采后果实生理生化及保绿效果的影响。结果表明:气调包装和乙烯吸收剂处理均能抑制果实呼吸强度和乙烯释放量上升,延缓果实叶绿素含量和ASA含量含量降低,保持果实硬度,但以气调包装效果更佳。二者处理均能提高果实中SOD的活性,同时抑制了POD活性上升;抑制生成速率。以上结果说明二者处理可能是通过维持果实活性氧代谢平衡和抑制果实吸收强度和乙烯释放量来延缓叶绿素降解。-O2•

Abstract: Effects of modified atmosphere packaging and ethylene absorbent treatment on physiology and green preservation in Green Mume were investigated at 25℃。The results indicated that in both modified atmosphere packating and ethylene absorbent treatment,the rate of respiration and production of enthylene slowed down and the contents of chlorphyll and ASA also reduced while fruit firmness was relatively maintained.The treatment of modified atmosphere packaging was better than that of ethylene absorbent.Both treatments improved SOD activity and inhibited the POD activity and the O2-.production rate as well in Green Mume fruits.It suggested that both treatments delayed the degradation of chlorophyll through maintaining the balance of activated oxygen metabolism and inhibiting the rate of respiration and production of enthylene in Green Mume fruits.
