中文摘要 | 蝴蝶蘭Doritaenopsis I-Hsin Bloody Mary 'KHM 2244'5.1 cm盆徑迷你株以l-MCP薰蒸預處理,搭配賞瓶包裝氣閉方式,探討其對瓶中花朵觀賞壽命之影響。結呆顯示:空氣流通(對照組)、半密封及1-MCP預處理後再半密封三種處理,相較於完全密封或1-MCP預處理後再完全密封處理,第一朵花朵壽命大幅增加24.8天,達41.4-48.8天。另調查植株移入瓶中後,呼吸率、乙烯釋放率、瓶內二氧化碳濃度及瓶內乙烯濃度,顯示經1-MCP預處理後,在對照組、半密封及1-MCP處理後半密封等處理,皆有效減少乙烯釋放率和C02產生率,並延援呼吸高峰與乙烯高峰釋放率的時間。而影響賞瓶內花朵壽命主要為氣閉條件,半密封條件花朵壽命顯著高於完全密封;此外測試"Dtps." I-Hsin Bloody Mary 'KHM 2244'對乙烯反應屬不敏成之非更年性花卉,適合瓶中花觀賞利用。配合使用1-MCP預處理後置於半密封條件,有效延長瓶中花朵觀賞壽命,可推薦瓶中花賞瓶利用。 |
英文摘要 | This study aimed to investigate the effects of airtight methods of viewing container and 1-methylcyclopropene (1-MCP) fumigation on the flower longevity in bottles of miniature "Dtps." I-Hsin Bloody Mary 'KHM 2244'. The results indicated that the packing conditions of air circulation (control), semi-sealed(SS) and semi-sealed after pretreated with l-MCP (1-MCP+SS) as compared to those of completely sealed (CS) and completely sealed (CS) after pretreated with l-MCP (I-MCP + CS) can increase the longevity of first flower (41.4-48.8) days. Besides, after the blooming plants were moved into the viewing container, the respiration rate, ethylene production, concentration of CO2 and ethylene in bottle were investigated during flowering period. The results indicated that packing conditions of control group, SS and l-MCP (I-MCP+SS) effectively decreased ethylene production and delay the peak of respiration rate and ethylene release rate in bottle flower. Therefore, the main effect of flower longevity of bottle flowers is airtight condition. The flower longevity of semi-sealed treatment is significantly higher than completely sealed. According to the ethylene test results, we also suggest that the miniature "Dtps." I-Hsin Bloody Mary 'KHM 2244' is an ethylene insensitive floral cultivar, that is suitable for shipping the miniature plants in viewing containers, it is recommended that pretreated the plants with l-MCP, and subsequently placed into a semi-sealed airtight condition will effectively extend the flower longevity in a viewing container. |
