关于云南水稻橙叶病的病状、传播方式、介体昆虫种类及传毒特性等的观察研究结果前已作了报道。唯病原未作研究。为了探明此病的病原问题,我们在室内将带毒的电光叶蝉(Recilia dorsalis)在水稻健苗上饲育接种,健稻逐渐出现水稻橙叶病典型症状后,将病株空运上海。取叶鞘部分于2.5%戊二醛pH7.2 0.1M磷酸缓冲液中固定过
About Yunnan orange leaf disease symptoms, modes of transmission, mediator insect species and transmission characteristics of the observation results have been reported before. The only pathogen was not studied. In order to find out the pathogen of the disease, we inoculated the poisoned Recilia dorsalis in the rice seedlings, and after the typical symptoms of the orange rice leaves appeared in Jian-rice, the diseased plants were air-borne in Shanghai. Sheath sections were fixed in 2.5% glutaraldehyde pH 7.2 0.1 M phosphate buffer
