摘要

品種特性、栽培溫度、光強度、肥料及除芽處理，均可影響文心蘭的開花品質及開花期。本研究以台中后里地區之文心蘭‘檸檬綠’為材料，調查不同月份去除葉芽對後續之生長與開花的影響，以評估花期調節的可能性。結果顯示於3月至7月中下旬萌發的新芽，其切花採收期落在11月中旬到隔年4月下旬，9月上旬到9月中下旬萌發之新芽其花期約在7至8月間。就利用除葉芽調節花期之目標，於3月下旬至5月下旬去除新芽，可將花期調節到11月下旬至2月中旬，或於9月上旬除葉芽將花期調節至7月中旬，以避開5至6月及9至11月的生產高峰期。

The quality and blooming season of Oncidium can be affected by characteristic of varieties, temperature, light intensity, fertilizer and bud-excision. The purpose of this study was to investigate the effect of leaf bud-excision in different seasons on growth and flowering of Oncidium Grower Ramsy 'Honey Angel', in order to test the possibility of off-season production in Houli, Taichung. Data showed when young leaf buds were excised during the middle of March to the end of July, flower stalks were harvested on the middle of November to late April. While buds excision was done during September, flower stalks were harvested on July to August. In order to escape high peak period of Oncidium production, leaf bud could be excised during the end of March to the end of May, then harvest dates were postponed to the end of November to the middle of February, or to the middle of July when excised during September.
