摘要/Abstract

摘要： 以“非洲骄傲”番荔枝果实为试材,研究了1-MCP(1-甲基环丙烯)处理对冷藏(15℃)番荔枝果实贮藏效果和生理变化的影响。结果表明:1.8μl/L1-MCP处理能显著提高番荔枝的好果率,延缓番荔枝贮藏前期TSS含量的上升,推迟其成熟软化进程;1-MCP处理还能显著抑制番荔枝果实VC含量的下降(p<0.01),提高果实贮藏后期SOD、POD和CAT的活性;同时,1-MCP处理抑制了果实中PPO活性的升高和MDA含量的积累。

Abstract: Experiment was conducted with sweetsop cultivar“ African Pride”(Annona squamosa L. cv. African Pride). The fruits were fumigated with 1.8μl/L 1-MCP (1-methylcyclopropene) for 17 hours at 25 ℃ and then stored at 15 ℃. The effects of 1-MCP treatment on storage quality and physiological changes of sweetsop fruits during cold storage were investigated. The results showed that 1-MCP treatment can increase significantly the rate of good fruits, delay the increase of TSS content in early storage and delay the ripening and softening of sweetsop fruits, 1-MCP treatment also can inhibit significantly the loss of VC content (p<0.01), and inhance the activities of SOD, POD and CAT in sweetsop fruits in late storage. In addition, 1-MCP treatment can decrease PPO activity and MDA content.

Key words: 1-MCP(1-methylcyclopropene), sweetsop, cold storage, quality, physiological changes
