许多国家均认为马铃薯纺锤块茎类病毒(PSTV)是一个危险的病原。因此,出口到一些国家的种薯需要进行PSTV检验,这种检验通常是以实验室检测为基础的,从每批种薯中随机抽取300～1000个薯块,检测PSTV和细菌环腐病。对于这样多的待测薯样,通常是从待测薯块上取下一小部分,
Many countries consider the potato spindle tuber virus (PSTV) as a dangerous pathogen. Therefore, PSTV tests are required for seed potatoes exported to some countries. Such tests are usually based on laboratory tests. 300-1000 tubers are randomly selected from each batch of potatoes to detect PSTV and bacterial ring rot. For so many potato samples to be tested, usually remove a small portion from the potato to be tested,
