• 中文摘要： 感染甘藷簇葉病、細花野牽牛簇葉病、絲瓜簇葉病、泡桐簇葉病、胡麻簇葉病及落花生簇葉病之植物病株莖組織切片之Dienes' stain染色及光學顯微鏡觀察後，發現篩管細胞內顯現特異性藍色染色反應，此項反應表示該篩管組織中之擬菌質體之存在。Dienes' stain對供試病株組織中的菌質體表現特異性染色反應，而對供試健全植株及病毒病株與柑枯立枯病株的篩管組織則無此項反應。感染簇葉病的長春草病株對Dienes' stain之特異性染色反應表現最靈敏且顯著。
• 英文摘要： Light microscopic observations of stemsections from various, diseased plants affectedwith sweet potato witches' broom, Ipomoeaobscura witches' broom, luffa witches' broom,paulownia witches' broom, sesame witches'broom or peanut witches' broom, showed specificblue staining reaction with Dienes' stain inphloem cells, which indicated the presence ofmycoplasma-like organisms (MLO) in thephloem tissues of infected plants. The stainappeared to be specific for MLOs, and gave noreaction in phloem tissues of stem sections fromhealthy plants and plants infected with virusesand citrus with Likubin. Witches' broom-infected periwinkle showed most sensitive anddistinctly specific reaction with Dienes' stain.
