2010年从贵州省黔南州烟草产区共采集201个表现明显马铃薯Y病毒病症状的烟草样本。采用Tas-ELISA检测PVY的3个株系PVYN、PVYO和PVYC。结果显示,201个样本中共检测出171个样本受到PVY侵染,其中PVYN37个,占21.6%;PVYO133个,占77.8%;PVYC0个,PVYN和PVYO复合侵染1个,占0.6%。PVY株系分布具有一定规律,侵染黔南州烟草的PVY以PVYO为主要株系,PVYN侵染相对较少,为次要株系,所有样本均没有检测到PVYC侵染,复合侵染零星发生。
In 2010, a total of 201 tobacco samples with obvious symptoms of potato virus Y disease were collected from the tobacco producing areas in Qiannan Prefecture, Guizhou Province. Three lines PVY, PVYO and PVYC of PVY were detected by Tas-ELISA. The results showed that 171 samples were detected by PVY in 201 samples, among which 37 were PVYN, 21.6% were PVYN, 133 were PVYO, 77.8% were PVYC, 1 were PVYC, 0.6% were PVYO and PVYO. The distribution of PVY strains has a certain rule. The PVY infected with tobacco from Qiannan Prefecture mainly contains PVYO, but PVYN infection is relatively minor, which is the minor strain. No PVYC infection was detected in all the samples. occur.
