摘要:

植物物候对气候变化的响应非常敏感,是指示全球变化对生态系统影响的重要证据。其中植物花期变化影响植物繁殖与进化,具有重要意义。大量研究表明,随着全球气候变暖,北半球植物始花期普遍提前。而关于气候变暖对植物始花期影响的内在机理并没有明确解释。植物激素是植物体内对植物开花等生理活动有显著调控作用的有机物,可对环境刺激作出响应并直接参与调控植物始花期,导致始花期的提前或延后。对植物激素在植物中表达与变化的精确测定有助于了解植物始花期对气候变化响应的内在机理。论文综述了植物激素对植物开花时间的调控作用以及目前植物激素最先进的检测方法,探讨了植物激素及相关代谢产物在植物体内的含量变化对植物始花期的影响;提出通过植物激素研究植物始花期对气候变化响应的激素调控机理,为探索植物物候对气候变化响应提供新的研究思路与手段。

Abstract:

Plant phenology is an important indicator of the impact of global change on biological systems because it is very sensitive to climate change. Flowering phenology is of great importance since it represents the major developmental transition of plants from the vegetative to the reproductive stage. Many existing studies have identified the advancement in first flowering date in response to global warming. However, the mechanism of first flowering date dependency on climate change remains obscure. Plant hormones play pivotal roles in almost every aspect in plant life including flowering. To understand the regulation of plant flowering phenology in response to climate change by plant hormones, accurate and efficient measurements of plant hormones are required. In this review, the functions and possible links between plant hormones and the change in first flowering date were discussed. Also, recently developed methods for plant hormone detection were briefly summarized, providing scientific techniques for understanding the underlying mechanisms of plant phenology in response to environmental stimuli.
