摘要

在台北陽明山的苗圃中發現合果芋有葉枯病的病徵，利用xanthomonad鑑別性培養基（Xan-D），可從病葉上V-型病斑上分離出細菌。以生理、生化、16S rDNA序列及Biolog測試分析，所分離出的細菌經鑑定為Xanthomonas campestris。經接種後，該細菌可在合果芋上產生病徵，但無法在火鶴花上引起病徵，因此應為X. campestris pv. syngonii，而不是X. axonopodis pv. dieffenbachiae。此為台灣對合果芋X. campestris細菌病害的首次報告。

Leaf blight symptoms on syngonium (Syngonium podophyllum) were observed in some nurseries in the Yang Ming Shan area, Taipei, Taiwan. Bacterial isolates were isolated from V-shaped lesions in diseased leaves by using xanthomonad differential (Xan-D) medium. The bacterium was identified as X. campestris based on physiological, biochemical, 16S rDNA sequence, and Biolog™ analyses. The bacterium isolated caused symptoms on syngonium but not on anthurium, and should be allocated to X. campestris pv. syngonii but not to X. axonopodis pv. dieffenbachiae. To our knowledge, this is the first report of this bacterium on syngonium in Taiwan.
