本文报导了节节麦（ＡｅｇｉｌｏｐｓｓｑｕａｒｒｏｓａＬ．）的条锈菌和小麦条锈菌七个生理小种交互接种均获成功的事实。并鉴定出节节麦条锈菌标样为标准的小麦条锈病菌条中２９号小种。证明了节节麦就是小麦条锈病菌的禾草寄主。另外，人工接种测定了节节麦对小麦赤霉病及白粉病的抗病性。 This paper reports the fact that seven physiological races of stripe rust and wheat stripe rust of Aegilopas quarrosa L. were successfully vaccinated. And the section of the stripe rust barley was identified as the standard barley stripe rust in the No. 29 race. It is proved that Arthropod is the grass host of wheat stripe rust. In addition, artificial inoculation was used to determine the disease resistance of Fusarium graminearum to wheat scab and powdery mildew.
