烟草丛枝病
1.
Tobacco witches broom symptom diseases spread by sap and aphids, no effect of acheomycin.
说明云南烟草丛枝症病害和烟草丛枝病是不同的病害，病原不是植原体，该病表现出病毒侵染的特征，可能由病毒或类似于病毒的病原引起。

云南烟草丛枝症病害
1.
Plasmalemmasome that was the characteristic of viroidinfected leaves had been observed in thin section of Tobacco witches broom symptom diseases, but twodimensional electrophoresis couldn t detect viroid.
感染云南烟草丛枝症病害的病苗的细胞切片中观察到类似于旁壁体的质膜体，旁壁体是类病毒侵染植物形成的特征病变结构，但多次双向电泳实验均未检测到类病毒分子，质膜体的形成可能和莫笑晗等发现的与云南烟草丛枝症病害相关的稳定ＲＮＡ有密切关系，但线性开环结构和失活温度说明其不具有类病毒核酸特征。
2.
The stable lowmolecularweight RNA associated with Tobacco witches broom symptom diseases was all found in witches broom symptom diseased tobacco from 22 counties and cities in Yunnan.
来自云南省２２个县市的烟草丛枝症标本均检测到与云南烟草丛枝症病害相关的稳定ＲＮＡ，大小相当于８００ｂｐ左右的ＤＮＡ；病株的根、茎、叶、花和枯叶中含有此ＲＮＡ，种子中未检测到此ＲＮＡ；此ＲＮＡ的最大吸收峰为２６９ｎｍ；能被蛇毒磷酸二酯酶Ｉ消化，不具有类病毒结构特征，推测可能是病毒的基因组分；支持莫笑晗等对此ＲＮＡ的结构推测，即可能是有广泛内部配对、具有类似发叉结构的线性长度为１６１ｋｂ的单链ＲＮＡ。

During 19941998,the measures of medicament cure and preventing the disease by killing insects had been taken in the serious diseased district of Tobacco witches broom symptom disease inYunnan and the demonstrating (3 115 hm2) and spread (64 032 hm2) the technology of the synthetical prevention and cure developed in many places.
１９９４至１９９８年，在云南烟草丛枝症病害的重病区进行药剂治疗和治虫防病等研究，并进行大面积综合防治技术示范（３１１５ｈｍ２）和推广工作（６４０３２ｈｍ２），结果表明：抗生素类药剂和抗病毒制剂无治疗效果，单纯治虫防病的效果也不理想，采用以网罩隔离育苗培育无毒苗、药剂控制传媒昆虫、淘汰和更换病苗、保健栽培为技术核心的综合防治措施，能够有效地控制病害的发生和流行，防治效果在９５％以上。
