为减少从国外大量引进热带兰试管苗，同时为脱毒工作作准备，我们对进口的多种热带兰进行了组织培养，摸索出能年产十几万至百万株试管苗的配方。对自行组培的试管苗和旅检截留的试管苗作了病毒检测，结果均检出建兰花叶病毒（ＣｙＭＶ），建议加强对进口试管苗的检疫和开展无毒试管苗生产。
In order to reduce the introduction of large numbers of Tropicum flavesceum seedlings from abroad and to prepare for the detoxification work, we have conducted tissue culture of imported Tropic orchid species and explored formulations capable of producing about 100,000 to one million test-tube seedlings annually. Tests on self-culture of test-tube seedlings and trip test-cut test-tube seedlings were performed to detect the virus. As a result, CyMV was detected. It is suggested to strengthen the quarantine of imported test-tube seedlings and to develop non-toxic test-tube seedlings.
