Abstract: 
本試驗以商業栽培品種‘Furore’和‘Ornella’非洲菊切花為材料,探討切花採收時離水時間對切花呼吸、乙烯生成、離子滲漏及瓶插壽命之影響。結果顯示,採收時離水時間長短,對舌瓣小花組織電解質滲透率影響不顯著。呼吸率介於2025 mL Kg-1 hr-1 之間,離水超過 8 小時,則二個供試品種之呼吸率皆降低,至離水 24 小時又上升。離水會使復水前的切花乙烯釋放量增加,‘Furore’ 對照組之乙烯釋放量為 0.56 μL Kg-1 hr-1 ,經離水 8 小時後增加二倍,為 1.23 μL Kg-1 hr-1 ;‘Ornella ’ 切花離水 4 小時內尚無偵測到乙烯之釋放,但離水 8、12 及24 小時後,乙烯釋放量則分別增為 1.5、3.31 及3.84 μL Kg-1 hr-1 。
Two cultivars of Gerbera jamesonii Bolus ‘Furore’ and ‘Ornella’ were tested in this study to investigate the respiration, ethylene production, electrolyte leakage and vase life of gerbera cut flowers of dehydration. There were no significant effects on the electrolyte leakage rate of the floret among treatments. Respiration rate between 2025 mL Kg-1 hr-1, Over 8 hrs from dehydration, the respiration rate of two cultivars was all reduced, and rise again 24 hrs later. Ethylene production increased as dehydration time extended, for ‘Furore’ ethylene production was 0.56μL Kg-1 hr-1
in control treatments. But in 8 hrs dehydration treatments, the ethylene production increased 2 fold higher than control treatments. For ‘Ornella’ there was no ethylene production in 0, 1, 2 and 4 hrs, but in dehydration 8, 12 and 24 hrs treatments, ethylene production increased to 1.5, 3.31 and 3.84μL Kg-1 hr-1, respectively.
