中文摘要
台灣的外銷蝴蝶蘭於運達國外後需經短暫時間恢復和催花，才能販售。本研究探討帶不同長度花梗的蝴蝶蘭經模擬貯運後的生長及開花表現。蝴蝶蘭Doritaenopsis Ruey Lih
Beauty ‘G92803’及Phalaenopsis Hsinying Lip ‘Hsin-Ying’兩品種苗株先置於25/20℃催花溫室中，待花梗長度達1.3±0.09，3.2 ±0.11，5.4±0.13，或7.4±0.15 cm 時，移到21±1℃模擬貯運1，2，3，或4 週。然後再調查其於25/20℃環境下之開花表現。結果顯示1-4週黑暗貯運對帶花梗Phal. Hsinying Lip ‘Hsin-Ying’影響光合作用不大。經貯運1-4 週的帶花梗Dtps. Ruey Lih Beauty ‘G92803’開花時最短的花梗及花序各為49.5 及25.5 cm；較未經貯運植株的64.9 及38.8 cm 短。前者總花朵數最少為13.7 朵，亦較未經貯運植株的25.5 朵少。又貯運時間愈長，開花表現愈差。帶花梗的Phal. Hsinying Lip ‘Hsin-Ying’植株比未抽梗的植株同樣經貯運1-4週後，提早31.4 天開花。前者開花時花梗及花序長可各達81.7 及43.7 cm；較後者的66.5 及30.3 cm 為長。前者總花朵數25.7 朵，亦較後者的15.5 朵為多。本試驗帶花梗之兩品種蝴蝶蘭經黑暗貯運1-4 週後，開花時仍可維持良好觀賞品質，但貯運時間之長短顯著影響其整體開花表現.
英文摘要
Two commercial cultivars of orchids, Doritaenopsis ‘Ruey Lih Beauty G92803’ and Phalaenopsis‘Hsinying Lip Hsin-Ying’, were grown in the flower-inducing greenhouse kept at 25/20℃ until their flower stalks reached the length of 1.3±0.09, 3.2±0.11, 5.4±0.13, or 7.4±0.15 cm. The plants were then kept in dark at 21±1℃ for 1, 2, 3 or 4 weeks,simulating long-distance surface shipment. After such treatments, plants were moved to growth condition at 25/20℃ for further observation of growth and flowering performance.The ability of photosynthesis of “Hsinying Lip Hsin-Ying” plants was not significantly affected by the simulated shipping treatment. However, the simulated shipping treatments substantially reduced the lengths of stalks and inflorescences as well as the number of flowers per stalk in ‘Ruey Lih Beauty G92803’.Furthermore, the longer duration of simulate shipping, the severer reductions occured.
In ‘Hsinying Lip Hsin-Ying’ plants, when plants with flower stalks and those without stalks were subject to simulated shipping,the former flowered earlier, had longer stalks and inflorescences, and had more flowers per stalk then the latter after both groups were subject to simulated shipping. All plants tested produced flowers with ornamental value after simulated shipping, but the duration of simulated shipping treatment had significant influences on the performance of post-shipping plants.
