    ..The arabinose to xylose ratio was low (approximately 0.2) and no 2,3-disubstitution existed. No blocks of substituted xylose residues could be observed along the main chain. ..

    ..It is postulated that these activities are essential for generation of tensile stress during fibre maturation in tension wood. ..
