摘要:
The 284 cucumber samples affected by virus in the fields of Shunyi and Changping Districts of Beijing,Shouguang of Shandong Province,and Shenzhen of Guangdong Province,were identified on their species of virus diseases and detected them with virus antibodies against 5 cucumber viruses,including Cucumber mosaic virus,Watermelon mosaic virus,Zucchini yellow mosaic virus,Cucumber green mottled mosaic virus and Papaya ring spot virus by ELISA method.The results showed that CMV,WMV,ZYMV were detected on the infected leaves of 126 and 124 samples collected in Shunyi and Changping Districts of Beijing.Among them the detection rate of CMV was the highest,all was 100.00% in Shunyi and Changping.The detection rate of ZYMV were 80.95% and 66.94%,respectively.The detection rate of WMV was the lowest - 51.59% and 53.22%,respectively.Only CMV was detected on the infected fruit.CMV,WMV,ZYMV,PRSV 4 viruses were detected on the infected leaves of 28 samples collected in Shouguang of Shandong Province.The detection rates of these 4 viruses were 100.00%,35.71%,35.71% and 17.86%,respectively.CMV,WMV,PRSV were detected on the infected leaves of 6 infected cucumber samples collected in Shenzhen.The detection rates were 100.00%,50.00% and 50.00%,respectively.Investigation discovered that the phenomenon of 2 and over 2 kinds of virus mixed infection on cucumber was very common in Shunyi and Changping Districts of Beijing, Shouguang of Shandong and Shenzhen of Guangdong.%采集北京顺义和昌平、山东寿光及广东深圳等地田间感染病毒病的黄瓜材料284份,利用黄瓜花叶病毒(CMV)、西瓜花叶病毒(WMV)、小西葫芦黄花叶病毒(ZYMV)、黄瓜绿斑驳花叶病毒(CGMMV)及番木瓜环斑病毒(PRSV)5种黄瓜病毒抗体采用酶联免疫吸附(ELISA)法对其进行病毒病种类鉴定.结果表明,顺义和昌平采集到的126份和124份病毒样品,均在其叶片上检测到CMV、WMV、ZYMV 3种病毒,其中CMV检出率最高,均为100.00%;其次是ZYMV,检出率分别为80.95%和66.94%;WMV检出率最低,分别为51.59%和53.23%;在感病果实上只检测到CMV.在寿光采集的28份发病叶片中,检测到CMV、WMV、ZYMV、PRSV 4种病毒,其检出率分别为100.00%、35.71%、35.71%、17.86%.在深圳采集的6份黄瓜感病材料中,检测到CMV、WMV、PRSV 3种病毒,其检出率分别为100.00%、50.00%、50.00%.调查结果还发现,在北京顺义和昌平、山东寿光及广东深圳均存在2种或2种以上病毒复合侵染的现象.
