新疆几种花卉病毒的鉴定

对所采集的百日菊、美人蕉、唐昌蒲病毒病的毒源标样,经鉴别寄主反应、电镜观察、物化属性测定、蚜传试验、种(球)传试验及血清学反应,百日菊的病原病毒鉴定为:黄瓜花叶病毒(CMV)、烟草花叶病毒(TMV)、番茄不孕病毒(TAV)、蚕豆萎蔫病毒(BBWV)。其中以 CMV 为主,约占64％。4种病毒均可通过汁液摩擦接种,不经种传。美人蕉病原病毒鉴定为黄瓜花叶病毒。其块根带毒率达45％以上。唐昌蒲病原病毒经鉴定为黄瓜花叶病毒。其球茎带毒率可达45％以上。

Identification of Several Flower viruses in Xinjiang

pathogenetic samples from Zinnia elegas Lau.,Canna india L. and Breeders Gladiolus Were studied by means of detecting host reaction, electron microscope,physical and chemical charascteristie determination,aphid boren and seed-borne virus experiments,and serological reaction.It is clear that the pathogenetic virus caused the Zinna elegans disease including CMV, TMV,TAV and BBWV.It showed from detection that the main pathoge- netic virus from Zinna elegans was CMV.All the four viruses communica- te through sap frication,but not seed.It was found that the pathogenetic viruses of India Canna were all CMV The virus-bearing content of Tube- rous root could be over 15%.It was also pointed out that the pathogene of Breeders Gladiolus was detected to be CMV.The Virus content in corm was 45%.
