摘要
以河套蜜瓜为试材,研究3种采收成熟度,1-MCP浓度50,100和500 nL·L^(-1),处理24 h后,在23℃±2℃下贮藏对后熟软化的影响。结果表明,1-MCP的作用效果与河套蜜瓜的成熟度之间存在着负相关关系。对组织乙烯系统Ⅱ未启动的成熟度Ⅰ和成熟度Ⅱ的果实,使用1-MCP处理才能抑制后熟和软化,对于组织已经产生大量乙烯的成熟度Ⅲ果实,1-MCP处理不再有抑制作用。对不同成熟度的河套蜜瓜后熟抑制的1-MCP有效浓度不同,成熟度愈低所需1-MCP有效浓度越小。
Taking Cucumis melo L.cv Hetao as test materials,the effects of three harvesting maturity,1-MCP concentration of 50,100 and 500 nL·L^（-1）,24 h later on host-Harvest and softening under the condition of 23 ℃±2 ℃ were studied.The results showed that there was a negative correlation between the 1-MCP effect and the maturity of Cucumis melo L.cv Hetao.The ethylene system II of the maturity I and maturity II fruits did not start;The treatment with 1-MCP could inhibit host-harvest and softening;1-MCP treatment was no longer inhibit to the maturity III fruits whose organization produced a lot of ethylene.The maturity of Cucumis melo L.cv Hetao was different,so the efficient concentration of inhibited 1-MCP host-harvest was different too;The less mature required the efficient concentration of 1-MCP was lower.
