本文叙述了可作为诊断特征的细菌在对宿根矮化病有不同反应的甘蔗品种体内的系统分布情况。用相差显微镜,可观察到甘蔗植株的所有部位(由根到叶片)的组织中的这种细菌,但是,最容易看到的是成熟茎的组织。将3个供试品种中的细菌数量作一比较,知道细菌的数量与甘蔗品种对宿根矮化病的发病程度有直接的关系。 This article describes the systematic distribution of bacteria that can be used as diagnostic features in sugarcane varieties that respond differently to stub stunting. With phase-contrast microscopy, this bacterium can be observed in the tissue of all parts of sugar cane plants, from the roots to the leaves, but the most readily visible is the tissue of mature stems. A comparison of the number of bacteria in the three tested cultivars shows that there is a direct relationship between the number of bacteria and the incidence of stubble disease in sugarcane varieties.
