| 摘 要： | 以姜荷花鲜切品种‘清迈粉’为试材,研究1-MCP熏蒸处理对姜荷花鲜切花在贮运期间生理变化的影响。结果表明：随着贮运时间的延长,切花失重率极显著增大,花瓣细胞膜透性和花青素含量显著增加,乙烯释放量总体上呈降低趋势。贮运期间,各剂量处理不同程度地抑制了SOD,POD,O2-和MDA4项生理指标的增加（高剂量处理的乙烯释放量除外）;2～4μL.L-1剂量处理极显著地抑制花瓣细胞膜透性、乙烯释放量和花青素的增加,但对失重率增大的抑制不显著。贮运第5天,各剂量处理都极显著地抑制了SOD和POD活性;2～4μL.L-1剂量处理显著地抑制MDA的产生;1-MCP熏蒸对O2-的抑制不显著;以4μL.L-1剂量处理对活性氧代谢抑制的综合效果最好。因此,确定4μL.L-1是常温下1-MCP对姜荷花鲜切花贮运的最佳处理剂量。

| Abstract: | Physiological changes of Curcuma alismatifolia cut flowers during storing,as well as the effects of fumigation method for 1-MCP on the physiological indexes and on the metabolism of active oxygen species were investigated. The results showed that,with the extension of the shipping time,the weightiness rate of the cut flower increased significantly,petal membrane permeability and anthocyanin increased significantly,while ethylene production decreased in general,during shipping and storing,different degree concentration deals inhibited the incresement of four physiological indexes in various degree; in the later period of shipping and storing,certain concentration of suffocating inhibited the augment of petal membrane permeability and releasing of ethylene observably,but had no significant effect on the increasement rate of weightiness; on the day five,four different degree concentration deals all inhibited SOD and PODs＇ activities,the produce of MDA was inhibited by 2-4 μL·L-1 of 1-MCP significantly,except for O-2. 4 μL·L-1 of 1-MCP had the best effect on active oxygen metabolizing. So,4 μL·L-1 1-MCP was the best dosage for the storing of curcuma alismatifolia cut flowers. |
