Fig. 6.2 Monosaccharide composition of herbaceous plants (a) and woody plants (b), adapted
from Murayama (1980) and Banno (2010) for (a) and Sugiura (2010) for (b), respectively.
EH-glucose easily hydrolysabe glucose, NEH-glucose non-easily hydrolysable glucose. Statistical
test: (1) There is a significant difference in the average of proportion of all monosaccharides except
for EH-glucose (symbol; α) between five herbaceous plants and four woody plants (Maries fir
(fallen trunk) is excluded). (2) Average proportion of each monosaccharide of five herbaceous
plant; NEH-glucose > xylose > EH-glucose > arabinose ’ galactose ’ mannose ’ rhamnose ’
fucose ’ ribose (’means no significant difference). (3) Average proportion of each monosaccharide of three coniferous trees (Maries fir is excluded); NEH-glucose > EH-glucose ’ arabinose ’
mannose > xylose ’ galactose > rhamnose ’ fucose ’ ribose
