侵染豌豆的两种病毒病的初步鉴定

IDENTIFICATION OF TWO PEA VIRUSES

从江苏、四川省豌豆田中表现花叶症状的病株上分离得到病毒分离物 P-89、P-23.经寄主范围、体外抗性、蚜传及种传试验,病毒粒体形态及内含体观察,血清学试验,P-89分离物鉴定为豌豆花叶病毒.P-23分离物为马铃薯 Y 病毒组成员.

Two isolates,P-89 and P-23,were isolated from pea(Pisum sativum L.)in Jiangsuand Sichuan Provinces.The identities of the virus isolates were determined by host rangeand symptoms,stability in sap,mode of transmission,partical morphology,inclusion bodyand serological difference,P-89 isolate was identified as pea mosaic virus(PMV).P-23 wasidentified as a member of potyviruses group.
