在马铃薯癌肿病菌的研究工作中,需要有一种测定休眠孢子囊活力的适宜而快速的方法。从在生长的马铃薯植株上病菌的侵染和发育情况来检查孢子囊活力,这种方法由于休眠孢子囊在成熟时发生的休眠期而难办。我们实验室做这种实验至少要一个月。对萌发的直接观察不大可行,游动孢子的释 In the research work of potato pathogenic bacteria, there is a need for a suitable and rapid method for measuring the activity of resting sporocysts. The examination of sporocyst activity from the infection and development of germs on growing potato plants is difficult due to resting dormant stages of resting sporocysts at maturity. It will take at least a month for our labs to do this kind of experiment. Direct observation of germination is not feasible, the release of zoospores
