中文摘要:针对1-MCP具有延缓跃变型果蔬成熟衰老的作用,以干包75株系菠萝蜜果实为试材,研究果实采后不同浓度(0,0.1,0.5,1.0 mg/L)1-MCP处理对果实乙烯、淀粉、纤维素、果胶、可溶性总糖等物质含量的影响。结果表明:1-MCP处理极显著地抑制了干包菠萝蜜果实采后乙烯的产生,延迟了乙烯高峰的出现。1-MCP处理极显著地抑制菠萝蜜果实中淀粉、原果胶、纤维素含量的下降和可溶性总糖、还原糖、蔗糖和可溶性果胶含量的增加,将果实中淀粉降解的启动时间延后了2 d,并显著地降低了菠萝蜜果实的蔗糖含量,但提高了还原糖的含量。此外,1-MCP处理还极显著地抑制了菠萝蜜果实贮藏后前6 d中的有机酸和VC含量升高。在室温下,l-MCP处理将菠萝蜜果实的货架寿命延长了6~10 d,其中0.5 mg/L 1-MCP处理效果最好。
外文摘要:With hard jackfruit -75 strain as the material , the effects of 1-MCP treatment with different concentrations (0,0.1,0.5,1.0 mg/L ) on ethylene production and contents of starch ,cellulose,pectin and to-tal soluble sugar were studied .The results showed that 1-MCP strongly inhibited ethylene production and de-layed the incidence of the peak of ethylene production .1-MCP treatment extremely significantly inhibited the descent of starch,pectin,cellulose and the ascension of total soluble sugars ,reducing sugars,cane sugar and soluble pectin,delayed the startup time of starch degradation by two days ,and markedly reduced the sucrose content .But 1-MCP treatment increased contents of reducing sugars .1-MCP treatment also extremly signifi-cantly suppressed the increase of organic acids and vitamin C in the first six days after storage .The shelf and storage life of fruit treated with 1-MCP was extended by 6-10 days at the ambient temperature of 25 ±1℃.In all the concentrations ,the effect of 0.5 mg/L 1-MCP treatment was the best .
