小麦条锈病菌的禾草寄主──节节麦

Aegilops squarrosa L.──A Host of Puccinia Striiformis West

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 reported a successful fact that a Puccinia strain from Aegilops square rosa L.and 7 races of Puccinia striiformis West. from wheat can infect each other. The sample of the former strain was identified to be the same as the latter race of CY29.This proved that Aegilops squarrosa L.was a new host of Puccinia striiformis West. In addition, the resistance of the Aegilops squarrosa L.to the wheat scab and powder mildew Was investigated.
