对于大量的观赏植物来说，阻断植物对乙烯的反应是延长花朵寿命的有效策略。本文将讨论进行这种干扰的最有效方法。大量化合物对乙烯产生和感知的影响已被评估。其中包括一系列张力烯烃。这导致发现环丙烯，其中包括1-甲基环丙烯（1-MCP）和许多其他取代的环丙烯在受体水平上有效地阻断乙烯反应。为了发现这些化合物的全部潜力，还需要进行大量的测试，但它们确实为延长观赏植物的采后寿命提供了有希望的新方法。此外，基因改造似乎是控制乙烯合成和感知的一种非常有效的方法。本文将对降低内源性乙烯产量和降低对乙烯敏感性的尝试进行综述。其中，利用拟南芥的突变体乙烯受体基因etr1-1似乎最有希望，特别是当它在花特异性启动子的控制下表达时。
For a vast number of ornamental species, blocking the plant’s response to ethylene is an efficient strategy to enhance the longevity of the flowers. The most effective ways to conduct such interference will be reviewed in this paper. A large number of chemical compounds have been evaluated for their effects on ethylene production and perception. Among these are a range of strained olefines. This has resulted in the discovery that cyclopropenes, among them 1-methylcyclopropene (1-MCP) and a number of other substituted cyclopropenes effectively block ethylene responses at the receptor level. A lot of testing remains to be done to uncover the full potential of these compounds, but they do offer promising new ways to extend the postharvest life of ornamentals. Also genetic modification appears to be a very effective way in controlling of ethylene synthesis and perception. Attempts to use both a reduced endogenous ethylene production and a reduced sensitivity to ethylene will be reviewed. Among these the use of the mutant ethylene receptor gene, etr1-1, from Arabidopsis seems most promising, especially when it is expressed under the control of a flower specific promoter.
