萱草属植物的花芽分化与开花特性

Flower Bud Differentiation and Flowering Characteristics of Hemerocallis

萱草属(Hemerocallis)植物花朵明艳,有极高的观赏价值和丰厚的文化内涵。萱草属花期短的特点使得植株整体观赏期大大缩短,成为萱草作为景观花卉面临的主要难题。随着现代分子生物学的不断发展升级,理想的观赏性状能够在短时间内有目的性地获得,使培育花期长及可以连续开花的萱草新品种成为可能,对萱草属的品种改良是积极的探索。本研究旨在全面梳理和总结萱草属植物的开花特点和相关研究成果,为了解萱草属的开花特点、调控机制,更好地开发适应观赏需求的新品种提供依据和参考。

The flowers of daylily(Hemerocallis)are bright and colorful,with high ornamental value and rich cultural connotation.The short flowering period makes the whole ornamental value lower,which was the main problem of daylily(Hemerocallis)as a landscape plant.With the continuous development of modern molecular biology,ideal ornamental traits can be obtained purposefully in a short time,making it possible to cultivate new varieties of daylily(Hemerocallis)with a long flowering period and continuous flowering.The purpose of this study is to comprehensively review and summarize the flowering characteristics and related research results of daylily(Hemerocallis),in order to provide reference for understanding the flowering characeristics and regulatory mechanism of daylily(Hemerocallis),and better developing new varieties to meet ornamental needs.
