当归抽薹开花及其调控途径研究进展

当归Angelica sinensis干燥根因具有补血活血、调经止痛、润肠通便等功效，广泛应用于临床。生产上通常二年生根用作药材，但甘肃岷县等主产区二年生植株出现30%以上的提前抽薹开花（即早薹开花），使得肉质根木质化不能入药。早薹开花导致严重减产问题一直是多年来困扰当归优质药材生产的最严重问题之一。以前人所发表研究论文、专著、专利以及生产实践经验为基础，综述了影响当归抽薹开花的内在和外在因素、调控抽薹开花的途径及利用生物技术手段揭示抽薹开花的机制等方面的研究进展，以期从内因和外因2个方面为共同调控当归早薹开花提供有效途径，为抽薹开花机制的深入研究提供借鉴。

Research progress on bolting and flowering of Angelica sinensis and regulation pathways

The dried roots of Angelica sinensis has been widely applied in clinical care due to its efficiencies in nourishing and activating blood, regulating female menstrual disorders and relieving pains, relaxing bowels, etc. The cultivated two-year-old plants normally harvested roots for medicinal uses emerge over 30% early bolting rate, which leads to the lignified roots that are useless in medicinal agents. The early bolting and flowering that are leading to serious yield reduction has been one of the most serious problems in the production of A. sinensis for many years. Here, based on previously published research articles, monographs, patents as well as practice experiences, the research progresses on the internal and external factors affecting bolting and flowering of A. sinensis, the pathways regulating bolting and flowering, the mechanism revealing bolting and flowering by biotechnological interventions were summarized, with the aim of providing effective pathways jointly internal and external factors for regulating bolting and flowering, as well as references for further revealing the mechanism of the bolting and flowering of A. sinensis.
