Manskaja (1959) reported that the younger parts of a plant may pro- duce lignin with a lower methoxy content than that of the mature tissue, and Wardrop and Bland (1959) have discussed a similar situa- tion in the genera Eucalyptus and Tilia. Since higher methoxy content is associated with a higher syringyl-guaiacyl ratio, and the higher.
