叶子花花期调控技术研究进展

叶子花是应用较多的盆栽观花和园林绿化植物,在中国南北方都有广泛应用。通过花期调控技术研究,使叶子花能够周年开花,极大地扩展其应用范围,提高商品价值;另外花期调控技术还可以使育种者缩短叶子花育种周期,加快育种进程。在此,综述了叶子花花期技术,叶子花花芽分化进程受环境因子影响,通过光照、温度、水分的调控可达到控制花芽分化的目的;叶子花营养生长可通过栽培管理来调控,从而达到花期调控的目的;植物生长调节剂处理不仅能调控花期,还能延长开放时间,提高开花质量。对叶子花花期调控技术研究进展进行综述,从光照、温度、水分、栽培管理和生长调节剂等几方面的调控阐述叶子花花芽分化和花期调控技术研究现状,并提出了叶子花花期调控的综合技术措施。

The Study Advance of Flowering Time Regulator of Bougainvillea glabya

As a kind of potted and landscape plant, Bougainvillea glabra is used widely all over the country. By the research in the flowering time regulator techniques, Bougainvillea glabra can flower all year round and its application range is widened. Consequently, its commercial value is also increased. In addition, the breeding period can be shortened whiles the breeding course can be quickened respectively. This article reviewed the research advance of flowering time regulator in Bougainvillea glabra. The flower differentiation of Bougainvillea glabra can be regulated by some relative environment factors including light treatments, temperature and water condition .The vegetative growth phase of Bougainvillea glabra can be controlled by the management condition so as to affect the flowering time. Whereas the use of growth regulators is not regulate the flowering time, but also can prolong the flowering time and improve the flower quality simultaneously.The Research Advance of Flowering Time Regulator in Bougainvillea glabra
