番茄早疫病菌(Alternaria solani)在实验室条件下不易产生孢子。但在测定番茄品种抗病性时,需要的孢子量很大。为了增加分生孢子的数量,国外一些学者先后采用了切割菌丝,使用不同培养基,各种光照射,培养基脱水,以及化学处理等技术。现就我们在实验室试用的几种诱导方法作如下评价。 Alternaria solani is hard to produce spores under laboratory conditions. However, the determination of tomato disease resistance, the need for a large amount of spores. In order to increase the number of conidia, some foreign scholars have adopted cutting hyphae, using different media, a variety of light irradiation, medium dehydration, and chemical treatment technology. Now we are in the laboratory test several induction methods for the following evaluation.
