Fig. 1From: Improved Mäule color reaction provides more detailed information on syringyl lignin distribution in hardwoodTransverse sections (20 μm thick) of birch treated with traditional (a–f) and new Mäule reagents (g–l) at 0–10 (a, d, g, j), 30–40 (b, e, h, k), and 60–70 (c, f, i, l) min following treatment. The sections were color photographed under white light (a–c, g–i) or excited with blue light (d–f, j–l)Back to article page
