芍药(Paeonia lactiflora Pall.)是芍药科芍药属多年生草本花卉,具有重要的观赏和药用价值,但芍药的花期短而集中,易枯萎导致花的质量降低。适宜的温度、光照、水分、营养和植物激素有助于促进芍药花芽分化和打破休眠。在促成和抑制栽培中,选用早、晚花品种,温度调控和外源物质也可控制芍药的花期。为有效延长芍药的供花时间,通过对近年来国内外相关文献的梳理归纳,阐述了芍药花芽分化发育和休眠的生理学机制、促成和抑制栽培等方面的研究进展,以期为芍药花期调控研究提供理论依据。

[Abstract]
Paeonia lactiflora Pall. is a perennial herbaceous flower belonging to the goldenseal family. It is famous for high ornamental and medicinal value. However, its utilization is limited by its short and concentrated flowering period, easiness to wilt which leads to reduced flower quality. Studies have shown that suitable temperature, light, water, nutrition, and plant hormones help promote flower bud differentiation and break dormancy. In terms of forcing and retarding cultivation, the flowering period of herbaceous peony can be controlled by choosing early and late flowering varieties, temperature regulation and exogenous substances. The paper reviews the physiological mechanism of flower bud differentiation and dormancy of herbaceous peony, and the ways of flower regulation such as forcing and retarding cultivation, aiming at improving the cultivation technology and providing theory basis for the regulation of flowering in herbaceous peony.
