Fig. 1From: Identification of developmental stage and anatomical fraction contributions to cell wall recalcitrance in switchgrassSchematic of switchgrass tillers used for this study. Tillers were harvested above either the 5th or 6th internode, and then separated into internodes, discarding the nodes and panicle. Internodes were further manually subdivided into leaves, leaf sheaths, and stems. Diagram is representative and not to scaleBack to article page
