| Outline of Final Research Achievements |
The process of lignin deposition in the course of leaf growth was investigated by DFRC analysis. The increase of lignin in leaves of Fagus, Magnolia and Cercidiphyllum was observed in a short period, from late April to mid May. The distribution of lignin in beech leaf was investigated in detail to find out the heterogeneity in lignin composition. Leaf vein separated from beech leaf contained lignin with low S/G ratio, and other blade tissue had apparently syringyl-rich lignin. The hypothesis that these syringyl lignin in leaf tissue has some defensive roles against light stress was denied by the results of increased S-lignin in leaves under weaker light condition.
