Abstract
Coryneform bacteria (1.10-3.20×0.18-0.32μm in size) were constantly observed by electron microscopy in nodal xylem of the ratoon stunting diseased sugarcanes collected from Nansei Islands, Japan. Ultrathin sectioned specimens of the diseased plants showed that the bacteria surrounded by the fibrillar material or homogeneous matrix were often distorted morphologically.
The bacteria multiplied more rapidly in the stem tissue of sorghum or corn than in that of sugarcane when inoculated.
