Mechanisms of flowering by low temperature of Phalaenopsis were investigated in terms of interaction between cytokinin (CK) and gibberellin (GA). CK concentration in axillary bud rose at 14 days after low temperature treatment (Low), and initiation of axillary bud development followed close on this peak. Peak of GA concentration in the bud and spiking from the bud appeared at 28 days and at 26 days after Low, respectively. Application of exogenous CK and GA induced spiking from axillary bud under non-flowering condition, high temperature. In addition, GA application induced flowering at apical meristem regardless of temperature conditions. Thus, it was suggested that flowering of Phalaenopsis was induced by GA. The floral induction of apical meristem of Phalaenopsis was found for the first time in the world. Because this phenomenon might contribute for production of novel plants which is valuable plant for horticulture, a patent was submitted.

从细胞分裂素(CK)和赤霉素(GA)相互作用的角度研究了蝴蝶兰低温开花的机理。低温处理后14天，腋芽中CK含量升高，腋芽发育开始接近高峰。芽中GA浓度的高峰出现在低谷后的28d，抽穗高峰出现在低谷后的26d。外源CK和GA在非开花高温条件下诱导腋芽抽穗。此外，无论温度条件如何，GA处理都能诱导顶端分生组织开花。由此可见，蝴蝶兰的开花是由赤霉素诱导的。蝴蝶兰顶端分生组织的成花诱导在世界上尚属首次。由于这一现象可能有助于生产具有园艺价值的新植物，因此申请了专利。
