我国小麦条锈菌寄主范围的研究

 通过温室接种及在栽培草圃和野外进行调查,本研究证实我国小麦条锈菌禾草寄主共有11属62种,其中麦薲草(Elymus tangutorum (Nevski) Hand.-Mazz.)等22种禾草过去国内外尚未见报道可作为该菌的寄主;另外还有16种禾草为国内首次报道的小麦条锈菌寄主。
分小种接种的结果表明,同一禾草材料的感病性,因小种的不同而异;同一小种的致病性也因禾草材料的不同而有所差异。同种但不同来源的禾草材料,对小麦条锈菌的反应也是不尽相同的。

ON THE HOST RANGE OF STRIPE RUST WHEAT IN CHINA

The results of greenhouse inoculation and grass nursery and field survey indicate that 62 grass species distributed over 11 gennra of Gramineae have been shown to be hosts of wheat rust. Among them 22 grass species are nitherto not reported as hosts of this rust in the world,and 16 species are new records of hosts of this rust in China.The results of inoculation with different races to the grasses indicate that the susceptibility of one grass species or grass variety differs to different races, and the virulence of one race also differs to different grass species or grass varieties.
