Abstract

裸根會造成蝴蝶蘭Phalaenopsis amabilis 及白花黃心品系(Phal. Asian Elegance × Phal. Taisuco Sheen ‘White flower’)乙烯生成量及呼吸率快速提升。黑暗貯運出庫之後，葉片外觀略失水軟化，根部呈現乾癟、木栓化等現象產生，但真正嚴重影響是在種植復水之後。當暗處理出庫後給予復水可促使ACC oxidase 活性提升，大白花品系下位葉、外側根及內側根與Phal. amabilis 的外側根均可測得酵素活性顯著的變化。大白花以下位葉19.29 nl/g.FW.hr 提升最高，蝴蝶蘭Phal. amabilis 則是外側根33.62 nl/g.FW.hr 變化較大。此活性的改變促使ACC 快速氧化成乙烯，造成復水後乙烯含量的上升，導致下位葉黃化，根部活性降低。進而造成各種生理現象的改變。試以藥劑處理後，分析出庫與種植7 天後蝴蝶蘭各種生理性狀，以浸漬蘋果酸100 mM 及脯胺酸5 mM 效果較佳。無論葉綠素、蘋果酸、可溶性糖含量以及根部活性各方面均可減少其損失，且於之後種植期間有較佳生育活力。 Bare root would make Phalaenopsis amabilis and Phal. hybrid ‘White flower’ (Phal. Asian Elegance × Phal. Taisuco Sheen) ethylene production and respiration rate increased quickly. After simulated dark transport, water loss and droop were found in leaves appearance, and roots became inactivity resulted in dry and shrinkage and suberizated. The most serious influence was following rehydration. Rehydration could make ACC oxidase activation after simulated dark transport. Measuring on enzyme activity in basal leaf, internal and external root of ‘White flower’ and internal root of Phal. amabilis became more vigority. The most higher enzyme activity of ‘White flower’ on the basal leaf was 19.29 nl/g.FW.hr, Phal. amabilis on external root was 33.62 nl/g.FW.hr. The changes of enzyme activity made ACC oxidized into ethylene quickly. Rehydration made ethylene production arised and led to yellow of basal leaf, set down root activity. Those results made more physiological changes successively. The changes of physiological properties of phalaenopsis which treated with chemicals from departure of storage room and transplanted for 7 days. Soaking in malate 100 mM and proline 5 mM made much more effect. After drenching malate and proline chemicals, chlorophyll, malate, total soluble sugar content and root activity had better works, and then could get more superior in nursery plant vigority after transplanted.
