Abstract
蝴蝶蘭為台灣重要的經濟花卉，但在溫室栽培與運輸過程中常受 Fusarium phalaenopsidis (舊稱 Fusarium solani f. sp. phalaenopsis) 感染，造成普遍且嚴重的黃葉病，影響出口品質與產值。然而，目前對該病害的生態，包括感染源的分布及侵染機制尚未明確，導致防治策略難以精準執行。為釐清其感染來源與傳播方式，我們結合 CDMR 半選擇性培養基與專一性引子對FphSP6F/FphSP6R，建立一套快速檢測流程，並針對蝴蝶蘭栽培環境進行系統性採樣與分析，發現病原菌廣泛分布於水牆及床架，甚至可能藉由蕈蚋傳播。研究結果不僅有助於瞭解病原生態，亦為防治策略提供科學依據，有助於精進蝴蝶蘭黃葉病的綜合管理對策，邁向永續管理之目標。
Phalaenopsis orchids are one of the most important ornamental export crops in Taiwan. However, during greenhouse cultivation and transportation, they are frequently infected by Fusarium phalaenopsidis (formerly Fusarium solani f. sp. phalaenopsis), resulting in leaf yellowing disease that compromises export quality and market value. Despite its detrimental impact, the ecological aspects of this disease including the distribution of inoculum sources and infection pathway remain poorly understood, hindering the implementation of effective control strategies. To elucidate inoculation sources and dissemination pathways of the pathogen, we established a rapid detection protocol by integrating CDMR semi-selective medium with the specific primer pair FphSP6F/FphSP6R. A systematic sampling and analysis of the orchid cultivation environment revealed that the pathogen was widely distributed on cooling pads and bench structures, and may even be vectored by fungus gnats. These findings provide critical insights into the ecology of F. phalaenopsidis and offer a scientific basis for more precise and effective disease management strategies, contributing to the sustainable management of leaf yellowing disease in Phalaenopsis production.
