Abstract: The microstructure and crystallinity of the Miscanthus floridulus culm was studied to improve the research quality,to find possible new uses,and to lay a foundation for its industrial use. Results showed that the M. floridulus cortex was the portion of the outermost layer without vascular bundles,the xylem was the portion of the inner ring with comparatively more and closely distributed vascular bundles,and the pith was the portion of the central white culm with few vascular bundles. The culm epidermis were made up of epidermal membrane,long cells,short cells,and stomatal apparatus. Long cells were mostly serrated alongside the long edge. And the long and short cells containing silica. Vascular bundles were comprised of xylem,phloem,and fiber cells. Protoxylem contained circular grain vessels or spiral grain vessels,whereas metaxylem contained woven grain vessels or pitted vessels. The main features of the basic parenchyma cell tissue were thin-walls with pits and starch grains. The relative crystallinity of M. floridulus without pith for the upper culm cellulose was 43.21%,for the central part was 42.08%,and for the lower part was 44.49%. Thus,relative crystallinity was similar and did not show obvious regularity.[Ch,2 fig. 1 tab. 15 ref.]
