中文摘要 | 本研究以日長、日夜溫度和植物生長調節劑等處理,測試仙履蘭產期調節技術之可行 性,作為建立開花栽培管理技術之參考。Paph. delenatii 以日長14 小時、日/ 夜溫20/15℃ 有最高開花率為22%,日長8 小時、4 種溫度處理下的開花率皆為0%。而Paph. Greyi 在 日長14 小時,開花率在25/15℃和20/15℃有最高開花率44%;日長8 小時處理,除了日/ 夜溫25/15℃開花率為22%,其餘3 種日/ 夜溫度的開花率為0%。Paph. spicerianum 以固 定日溫25℃,夜溫15 ~ 20℃進行催花處理,有80%以上的開花率。激勃素與細胞分裂素 分別對Paph. Ho Chi Minh 有60%催花效果。Paph. charlesworthii 和Paph. venustum 不論有 無植物生長調節劑處理,日/ 夜溫25/15℃皆有60%以上的開花率。日/ 夜溫度25/15℃對 Paph. liemianum 和Paph. primulinum 有良好之催花效果,在此溫度條件下,2 ppm GA4+7 + 200 ppm 6-BA 對Paph. primulinum 之開花率可由40%提高至73%。現有技術: 仙履蘭栽培以採行大規模種植、傳統蘭花肥培管理、自然開花的生產模式, 無有效且精準的花期調節技術。 創新內容: 提供環境因子與植物生長調節劑與仙履蘭開花生理特性的關聯性,改善仙 履蘭花期不整齊集中的問題,有助於調整花期,提高開花一致性。 對產業影響: 提供業者達成產期集中的栽培方法,可望改變市場銷售的交貨規格,將 帶花梗株時期提前至大苗時期,提升蘭園生產的週轉效率,增加商業化 量產栽培的可能性。 |
英文摘要 | Paphiopedilum orchid is one of the potential orchids in Taiwan. However, the flower forcing of Paphiopedilum orchids is still unclear. To understand the way to promote the flowering response in Paphiopedilum orchids, several treatments were conducted to determine whether daylength, temperature or plant growth regulators could influence flowering time. In long days (LD), Paph. delenatii represented higher flowering rate at 20/15°C (day/night) than other three day/ night temperatures and no flowering responses in short days (SD). Paph. Greyi represented 44% flowering rate at 25/15°C and 20/15°C in LD. Paph. spicerianum prefer its specific day/night temperature at 25°C/15 ~ 20°C to flowering. Gibberellins and cytokinins treatments had been conducted in Paphiopedilum species and hybrids, such as Paph. Ho Chi Minh, Paph. liemianum and Paph. primulinum under the specific day/night temperature and showed the improvement of flowering response. Paph. charlesworthii and Paph. venustum represented higher flowering rate (> 60%) at 25/15°C whether plant growth regulators treat them or not .Based on these results, these data might be helpful to establish the flowering manipulation technique for Paphiopedilum orchids and improve the production techniques of Paphiopedilum orchids.What is already known on this subject? Traditional nutrition management and flowering under natural conditions are commonly used in the commercial cultivation of Paphiopedilum. What are the new findings? We studied the correlation among environmental factors, plant growth regulators and flowering habit of Paphiopedilum orchids. The results can help to adjust the flowering season in forcing culture. What is the expected impact on this field? Adjust the flowering season, improve the management efficiency, increase the yield/volume of Paphiopedilum. |
