摘要
综述了影响兰花衰老的外部因素、衰老过程中内部组织代谢变化、乙烯合成及信号传导通路调控兰花衰老的分子机制,总结了常见的兰花切花和盆花中常用的保鲜处理技术手段、处理后的应用效果及兰花衰老相关基因改良研究;展望了利用现代基因工程技术,通过调控功能基因延缓兰花衰老进程而实现延长兰花观赏期的新途径。
Orchid senescence caused by the external factors,the metabolic changes of internal organization during the senescence process,and the molecular mechanism of ethylene synthesis and signal transduction pathway regulating orchid senescence were reviewed.The common commercially popular fresh-keeping treatment technologies for cut and potted orchids and their application effects after treatment,and the improvement of orchid senescence-related genes were summarized.Additionally,modern genetic engineering technologies to delay the orchids senescence process and prolong the ornamental time by regulating functional genes were prospected.
