Content of Total Phenols in Red Heart and Wound-Associated Wood in Beech (Fagus sylvatica L.)

The structure of wound-associated wood has been relatively well studied in beech, but only a little information about the occurrence of extractives and particular classes of compounds in these tissues is available. We examined the content of total phenols and variability in their distribution in sap...
