Figure 10: a. Leaf bulk cell wall monosaccharide composition from control and drought stressed poplar trees one day following cessation of soil moisture additions. Monosaccharides quantified are fucose (Fuc), rhamnose (Rha), arabinose (Ara), galactose (Gal), glucose (Glc), xylose (Xyl), mannose (Man), galacturonic acid (GalA) and glucuronic acid (GlcA). b. Also shown are leaf bulk cell wallO -acetyl methyl ester content released following saponification of alcohol insoluble residue (AIR) preparations of control and drought stressed leaves on day 1, 4, and 7 of the drought. Values are plotted as average +/- one standard deviation (ns indicates no statistical significance between control and drought treatments, * indicates statistically significant differences, P < 0.05). Note, no statistically significant differences were observed in monosaccharide composition between control and drought treatments during days 1,4, or 7.
