香蕉贮藏过程中多胺与乙烯的关系

以巴西香蕉为试材,研究了随着果实后熟程度的增加,果实中精胺、亚精胺和腐胺三种多胺与乙烯生成之间的关系。结果表明:精胺与乙烯生成之间存在比较明显的拮抗关系,但随着乙烯生成量的增加,亚精胺释放量只有轻微下降;同时,腐胺略有上升;采用外源腐胺处理果实,发现乙烯生成受到一定程度的抑制,且与外源腐胺浓度成正比;结合内源腐胺与乙烯的关系,综合分析表明,腐胺含量的增加可以抑制乙烯的生成。

Relationship Between Polyamines and Ethylene in Banana During Storage

The Brazilian banana was used for studying the relationship between polyamines(Spd,Spm and Put )and ethylene during storage.It was indicated that there was a relatively apparent competition relation ship between Spm and ethylene;Spd only slightly declined with ethylene's increasing;at the same time ,Put only rose a little.Banana fruit treated with extrinsic Put caused the releasing of ethylene was restrained to a certain degree,meanwhile there was a direct ratio relationship be-tween them.Combined the relationship of endogenous Put and ethylene,it was indicated ethylene production was inhibited with the increasing of Put concentration.
