Abstract:

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.

Key words: orchid, senescence, ethylene-sensitive, preservation technology, genetic engineering
