早熟禾是优良的草坪草和牧草,近年来,天津出入境检验检疫局多次从进境的草地早熟禾、加拿大早熟禾及一年生早熟禾上截获一种腥黑粉菌,暂名为Tilletia sp.。针对T.sp.、早熟禾上的形态相近的T.sterilis、T.togwateei,以及同属近似种雀麦腥黑粉菌T.bromi和禾草腥黑粉菌T.fusca在冬孢子形态特征、萌发特性及细胞学性状等方面进行了系统比较。结果表明,Tilletia sp.与T.sterilis、T.togwateei存在较大差异,与T.bromi和T.fusca差别不明显;截获菌与Tilletia sp.在菌瘿、冬孢子形态特征上与T.bromi更为接近,根据研究结果将Tilletia sp.定名为T.bromi。
Bluegrass is an excellent lawn grass and pasture, in recent years, Tianjin Entry-Exit Inspection and Quarantine repeatedly admitted grassland bluegrass, Canadian bluegrass and annual bluegrass caught a Tung brown fungus, tentatively named Tilletia sp .. For T.sp., T. tritici and T. togwateei with similar morphologies on Kentucky bluegrass as well as their morphological characteristics of teliospores, T. gomi and T. fusca, Germination characteristics and cytological aspects of a systematic comparison. The results showed that Tilletia sp. Had significant difference with T. tritilis and T. togwateei, but not obvious with T. bromi and T. fusca. The intercepting bacteria and Tilletia sp. Closer to each other, Tilletia sp. Is named T.bromi based on the results of the study.
