摘要:以早金舔梨为试材,研究其分别经1、2、4包/10kg的1-MCP处理后,放置在(23士1)℃室温下贮藏16d的品质
变化情况。结果表明,1-MCP处理较好地保持果实中总糖、可叮滴定酸和Vc的含量,维持果实硬度,抑制果实的呼吸强度,
降低了果实的腐烂率,提高了果实的品质,以2包/10kg的1-MCP处理效果最好
关键词:早金酥梨;1-MCP缓释剂;贮藏品质

Abstract: lsing Zajinsu pear as the materials, the changes of fruit quality during 16 days storage by the treat
ment of 1, 2, 4 packs/10 kg I-MCP concentration were studied, the fruits were storaged under(23+1)C
tem
erature. The results showed that: the content of total sugar, titratable acid and Vc were well maintained, the
firmness was maintained, the respiration was suppressed, the decay rate was declined, the quality was en
hanced by the 1-MCP treatment, the concentration of 2 packs/10 kg had the best effect
