“…The total amount of cell wall material in shoot tissue of red‐osier dogwood remained unchanged during salt stress. The cell walls of untreated red‐osier dogwood seedlings contained 24.2% hemicellulose, an amount similar to other woody plants, such as white spruce ( P. glauca ) (Zwiazek 1991; Bikova and Treimanis 2002). Hemicellulose content was increased in red‐osier dogwood seedlings treated with NaCl.…”

Red-osier dogwood (Cornus stolonifera Michx, Syn. Cornus sericea), a species relatively well adapted to moderately saline conditions compared with other boreal species, was used to test the effects of NaCl on plant water relations, cell wall elasticity, and cell wall composition of seedlings. Three month-old seedlings were treated hydroponically with 0, 25, and 50 mm NaCl for 21 days. The osmotic potential at full turgor, osmotic potential at turgor loss, pressure potential at full turgor, and relative water content at turgor loss of red-osier dogwood shoot tissue were not significantly affected by the NaCl treatments. Cell wall elasticity of the shoot tissues did not change following NaCl treatments, suggesting that elastic adjustment did not play a role in the adaptation mechanism. Hemicellulose content of the cell wall increased in salt treated seedlings. The primary sugar found in the cell wall hemicellulose fraction was xylose. In the pectin fraction arabinose and galacturonic acid were the main sugars. Sodium chloride stress did not alter the sugar composition of the hemicellulose fraction; however, NaCl did increase the amount of rhamnose in the pectin fraction. The results of this study suggest that at moderate salinity red-osier dogwood does not make any osmotic or elastic adjustments in the shoot tissue, but some changes in the cell wall composition do occur. These changes could contribute to the decrease in growth recorded in red-osier dogwood during NaCl stress.

“…The properties of hemicellulose are dependent on its chemical structure. [150][151][152][153] Hemicellulose is present in both hardwood and softwood. Softwood hemicellulose contains glucomannan, arabinan, galactoglucomannan, and a small portion of arabino-(4-O-methylglucurono)-xylan.…”
