EFFECTS OF ENVIRONMENTAL FACTORS ON FORMATION OF LIGNIN IN EUCALYPTUS CAMALDULENSIS DEHN. GROWN IN KHOSESTAN-IRAN

Peroxidases are enzymes which catalyse two final steps in the wood lignin biosynthesis. The connection between xylem peroxidase activities and wood xylem lignifications was examined by determining peroxidase activities in the stems of eucalypt (Eucalyptus camaldulensis Dehn.) trees during two season...
