CIL:40383

Scanning electron microscope image of a cross-section through an Oryza sativa (Rice) stem, showing the vascular bundles arranged in two rings and central pore (usually filled with mucilage, but collapsed in this image). This image is part of a group on botanical stems (CIL:40378-40395).本图像为水稻（Oryza sativa）茎秆横切面的扫描电子显微镜成像结果，可见其维管束呈两轮排列，且带有中央孔隙——该孔隙通常充满黏液，但在本图像中已发生塌陷。本图像隶属于植物茎秆相关图像集（CIL:40378-40395）。
