小麦条锈病菌(Puccinia striiformis f.sp.tritici)生理小种划分的依据是对品种苗期的致病性,其致病性必须通过寄主植物方能表现出来,病叶就是寄主—病原物相互作用的结合体。有关条锈病菌的人工培养尚无报道。秆锈病菌和叶锈病菌的人工培养研究表明,专性寄生锈菌在人工培养过程中的变异很大,其在遗传、进化和分类研究中的应用前景尚难以作出肯定的评价。如果以相应病叶作为小种分析的材料,将有助于尚不能人工培养的
The rationale of the physiological races of Puccinia striiformis f. Sp. Tritici is based on the pathogenicity of the seedlings at the seedling stage. The pathogenicity of the wheat seed races must be demonstrated by the host plants. The diseased leaves are the host- The role of the combination. Artificial culture of stripe rust has not been reported yet. Artificial cultivation of stem rust and leaf rust showed that there were great variability in the process of obligate parasitic rust in the process of artificial cultivation, and its application prospect in genetics, evolution and taxonomy could not be affirmed. If the corresponding diseased leaves as racial analysis of the material, will help not yet artificial cultivation
