以广东高州香蕉为实验材料,研究了1-甲基环丙烯对成熟香蕉老化斑点产生的影响。结果表明:即使催熟至批发成熟度(果皮3/4面积变黄)和零售成熟度(果皮转黄)的香蕉,0.5和1.0μL/L的1-MCP处理,仍可显著延迟果皮衰老斑点的产生,延长货架寿命;1-MCP处理延迟了批发成熟度香蕉果皮褪绿和果肉淀粉降解,对于抑制2种成熟度的香蕉货架后期组织崩溃水渍症状的出现,也具有良好效果,处理效果以批发成熟度更好;2个1-MCP剂量间无显著差异。

This paper studies the influence of 1-MCP on specks of ripen bananas.The results showed that: 0.5 and 1.0 μL/L 1-MCP treatment can obviously retard the occurrence of the specks and extend the shelf life even for those are speeded ripening for wholesale(3/4 peel yellow or fully)or retail(peels turns yellow).Moreover,1-MCP treatments delayed the peel green color changes as well as the starch decomposition;it also prevented browning and watering of the fruits during the storage.This research was useful on reducing the postharvest losses and relatively increasing the commercial value of bananas.Two different doses of 1-MCP treatment did not show significant difference.
