据我们于80年4～7月观察,在田间或收获后的病叶上,只有苏麦3号、鄂麦6号等少数发病严重的品种上,约有千分之几的病叶上的闭囊壳内有子囊孢子,而且病叶上也不是所有的闭囊壳都有子囊孢子。在室内把有或无子囊孢子的闭囊壳放在叶上都未发病,但用抖落分生孢子接种作对照发病却很重。后来用麦叶浸水保湿法又连续做了数次子囊孢子形成试验,也未见子囊孢子的形成。为了弄清这个问题,同年10月份后,又进一步作了研究。
According to our observation from April to July in 1980, only a few percent of the diseased leaves on the diseased leaves in the field or post-harvest were only Sumai No. 3 and Emai No. 6, There are ascospores in the closed capsule shell, and not all the closed capsule shells contain ascospores. In the room with or without ascospores closed shell on the leaves were not disease, but shake off the conidia inoculated for the control of the disease is very serious. Later with wheat leaf water moisturizing method and made several consecutive ascospore formation test, also did not see the formation of ascospores. In order to clarify this issue, in October the same year, further research was made.
