  1. aChemical properties of five cultivars of wheat straw from two sites (H = Holstebro and F = Fynen) before and after hydrothermal pretreatment (195°C, 10 min). Values are averages (n = 3), and standard deviations are given in parentheses. Cell = cellulose, Hemicell = hemicellulose. Variation in biochemical compounds within materials from both sites and the individual sites are presented at the bottom.
