北美鹅掌楸是一种观赏性很强的树种,1987年科研人员在卡罗来纳州的Ashe县一株较大的北美鹅拿楸上首次发现一种病毒病。利用嫁接接种、汁液接种等方法对其研究,通过Joelloos转换电子显微镜(60KV)观察病毒样本,并进行血清学试验,证实这是一种不同于杨花叶病毒病的新病毒病,Ashe县已发生小范围传播,应引起重视,防止矮化大量发生。
Liriodendron tulipifera is a highly ornamental tree species. In 1987, researchers first discovered a viral disease on a large North American gooseberry in Ashe County, North Carolina. Grafting inoculation, juice inoculation and other methods of their study, by Joelloos transition electron microscopy (60KV) to observe the virus samples, and serological tests confirmed that this is a new virus disease different from the mosaic virus disease, Ashe County has Occurrence of small-scale spread, should pay attention to prevent dwarfing occurred in large numbers.
