摘　　要：地下芽植物是植物芽位分类中的一个重要类别,许多观赏花卉属于地下芽植物。它们通过全部或部分覆盖于生长基质表面之下的芽或延存器官的休眠来适应寒冷等不利环境。因此,地下芽休眠的调控机制是观赏花卉研究领域里的重要内容。本文系统综述了过去十余年间地下芽观赏花卉的生理休眠诱导、维持和解除过程中的生理和分子调控机制研究结果,涉及光、温等外部环境因素和激素代谢、碳水化合物转换、活性氧清除、次生代谢、表观遗传、共质体胞间运输等内在因素。随后,将地下芽观赏花卉与芽休眠研究的模式植物杨树的研究结果和实验方法进行比较,并分析了地下芽观赏花卉中的2类重要植物(宿根花卉和球根花卉)的芽休眠特征。本文有助于园林植物与观赏园艺界全面了解地下芽休眠的最新研究进展,也可为花卉栽培和生产实践提供系统的理论支持。The underground-bud plants,namely,the geophytes,constitute an important category in bud classification of plants.These plants include a significant number of ornamental flowers.These plants adapt to cold and other unfavorable environments through the dormancy of buds(including persistent organs)that are partially or fully covered beneath the surface of the growth substrate.Therefore,the regulatory mechanism of underground-bud dormancy is a crucial aspect in the research field of ornamental flowers.In this paper,we systematically reviewed the research findings on the physiological and molecular regulatory mechanisms involved in the induction,maintenance,and release of endodormancy in underground-bud ornamental flowers over the past decade or more.They covered external environmental factors such as light and temperature,as well as internal factors such as hormone metabolism,carbohydrate conversion,reactive oxygen species clearance,secondary metabolism,epigenetics,and intercellular communication via symplast.Subsequently,a comparison of various research findings and experimental methods was conducted between underground-bud ornamental flowers and Poplar spp.,which is the model plant for bud dormancy research.Finally,we analyzed the bud-dormancy research characteristics of two important categories in underground-bud ornamental flowers(perennial flowers and bulbous flowers).This review helps to comprehensively understand the latest research progress of the underground-bud dormancy research in landscape plant and ornamental horticulture field and can provide systematic theoretical support for flower cultivation and production.
