Red pitaya (Hylocereus sp.), which flowers between May and October and sprouts between November and May in Taiwan, has been confirmed to be a long-day plant.
The areoles on the old shoots may be induced to flower after the March equinox naturally, and the floral bud formation occurs in two to three waves from May to October.
We conducted experiments on photoperiodic regulation of floral bud formation from June to Dec. 2009 and tested the feasibility of off-season production in 2011.
Shortening summer daylength to 8 h inhibited the areoles at the distal end of the shoots to develop into floral buds and promoted sprouting at the proximal ends of the shoots.
Night-breaking treatment between the September equinox and the winter solstice led to floral bud formation.
The critical daylength seemed to be ≈12 h, and night-breaking treatment would be applicable between the September and the next March equinoxes to produce off-season crops.
The duration of night-breaking required for flower differentiation was longer in the cooler than in the warmer season.
Four weeks of night-breaking treatment was sufficient to promote flowering in late fall (mid-October to mid-November), but 3 months were required to generate similar result in the winter and early spring (January to March) in southern Taiwan.

第二篇文章終於在楊老師的督促與大力協助下發表出刊了 ~>.<~
我的研究生生涯 剩下最後一個階段 這學期即將畫下美麗句點 :)
接踵而來的是更多實務及學術結合面的挑戰
面對多變的氣候條件及詭譎的市場波動
更需善用以往所學的知識作為實務應用上的基礎
期盼 在未來能在遙遠的TM開花結果............................
