对日本菟丝子有较强致病力的刺盘孢菌,其在PDA培养基上的特点是,菌落桔红色,产孢量大,气生菌丝稀疏,不形成分生孢子盘和刚毛。 不太可能筛选出一个对所有寄主上的日本菟丝子都有较强致病力的菌株,但完全有可能筛选出对其中少数几个主要寄主上的菟丝子均有较强致病力的菌株。 高温高湿和伤口对菌株的侵染有利;菌株的孢子悬浮液中加入2％蔗糖或少量菟丝子压榨液可促使孢子提早萌发并提高其萌发率。 菟丝子的茎蔓尤其幼嫩部分比花穗更易感病。 固体扩大培养基的成分中,用80％麦麸加20％玉米粉配制较好,菌株的产孢量大。
On the Japanese Cuscuta has strong virulence of Cercospora, its PDA medium is characterized by colony orange red, sporulation large, sterile mycelium sparse, do not form conidia disk and bristles. It is unlikely to screen a strain that has a strong virulence on Japanese dodders on all hosts, but it is entirely possible to screen for strains that have a strong virulence on dodder on a few of the major hosts. High temperature and high humidity and wound infection of the strain beneficial; strain of spore suspension by adding 2% sucrose or a small amount of dodder press liquid can promote spore germination and improve the germination rate. Dodder stalks, especially the tender part of the more susceptible to disease than spikes. Among the components of the solid expanding medium, 80% wheat bran and 20% corn flour are better prepared, and the sporulation amount of the strain is larger.
