The post-harvest phase of potato tuber dormancy and sprouting are essential in determining the economic value. The intricate transition from dormancy to active growth is influenced by multiple factors, including environmental factors, carbohydrate metabolism, and hormonal regulation. Well-established environmental factors such as temperature, humidity, and light play pivotal roles in these processes. However, recent research has expanded our understanding to encompass other novel influences such as magnetic fields, cold plasma treatment, and UV-C irradiation. Hormones like abscisic acid (ABA), gibberellic acid (GA), cytokinins (CK), auxin, and ethylene (ETH) act as crucial messengers, while brassinosteroids (BRs) have emerged as key modulators of potato tuber sprouting. In addition, jasmonates (JAs), strigolactones (SLs), and salicylic acid (SA) also regulate potato dormancy and sprouting. This review article delves into the intricate study of potato dormancy and sprouting, emphasizing the impact of environmental conditions, carbohydrate metabolism, and hormonal regulation. It explores how various environmental factors affect dormancy and sprouting processes. Additionally, it highlights the role of carbohydrates in potato tuber sprouting and the intricate hormonal interplay, particularly the role of BRs. This review underscores the complexity of these interactions and their importance in optimizing potato dormancy and sprouting for agricultural practices.
马铃薯块茎休眠和萌芽的采后阶段对经济价值至关重要。从休眠到活跃生长的复杂转变受多种因素影响,包括环境因素、碳水化合物代谢和激素调节。温度、湿度和光照等成熟的环境因素在这些过程中起着关键作用。然而,最近的研究扩展了我们的理解,包括其他新的影响因素,如磁场、冷等离子体处理和 UV-C 辐射。脱落酸(ABA)、赤霉素(GA)、细胞分裂素(CK)、生长素和乙烯(ETH)等激素作为关键信使,而油菜素内酯(BRs)已成为调控马铃薯块茎萌芽的关键调节剂。此外,茉莉酸(JAs)、独脚金内酯(SLs)和水杨酸(SA)也调节马铃薯休眠和萌芽。本文深入研究了马铃薯休眠和萌芽的复杂机制,强调了环境条件、碳水化合物代谢和激素调节的影响。探讨了各种环境因素如何影响休眠和萌芽过程。此外,还强调了碳水化合物在马铃薯块茎萌芽中的作用以及激素之间的复杂相互作用,特别是 BRs 的作用。本文综述强调了这些相互作用的复杂性及其在优化农业实践中马铃薯休眠和萌芽的重要性。
