Orchids are the flowers of magnetic beauty. Vivid and attractive flowers with magnificent shapes make them the king of the floriculture industry. However, the long-awaited flowering is a drawback to their market success, and therefore, flowering time regulation is the key to studies about orchid flower development. Although there are some rare orchids with a continuous flowering pattern, the molecular regulatory mechanisms are yet to be elucidated to find applicable solutions to other orchid species. Multiple regulatory pathways, such as photoperiod, vernalization, circadian clock, temperature and hormonal pathways are thought to signalize flower timing using a group of floral integrators. This mini review, thus, organizes the current knowledge of floral time regulators to suggest future perspectives on the continuous flowering mechanism that may help to plan functional studies to induce flowering revolution in precious orchid species.
兰花是具有磁性美的花朵。它们绚丽夺目，形状壮观，是花卉行业的王者。然而，人们期待已久的开花期却是它们在市场上取得成功的一个障碍，因此，调控开花时间是兰花花卉发育研究的关键。虽然有一些稀有的兰花具有连续开花的模式，但分子调控机制仍有待阐明，以找到适用于其他兰花物种的解决方案。人们认为，多个调控途径，如光周期、春化作用、昼夜节律、温度和激素途径，利用一组花整合素来信号传递开花时间。因此，本篇综述整理了目前关于花时调控因子的知识，提出了对连续开花机制的未来展望，这可能有助于计划功能研究，以在珍贵的兰花物种中引发开花革命。
