Fig. 1From: Physical–chemical properties of cell wall interface significantly correlated to the complex recalcitrance of corn strawThe cluster heatmap of saccharification ratios of different fractions from 12 corn cultivars. The selected fractions were leaf, leaf sheath, stem rind and stem pith, respectively. The color legend of dark purple to light purple representing saccharification ratios were automatically generated at the top right side of the figureBack to article page
