Resumen
RADIAL AND APICAL VARIATION IN RESIN CANALS OF RADIATA PINE WERE STUDIED. THE FREQUENCY AND SIZE OF RESIN CANALS WERE EXAMINED, USING MICROSCOPIC TECHNIQUES FROM A COMMERCIAL SOFTWARE. WOOD SAMPLES FROM STANDING TREES WERE TAKEN, SHOWING THREE DIFFERENT LEVELS OF EXTERNAL RESIN-BLEEDING INTENSITY : MODERATE, LIGHT AND INTENSE. THE VARIABILITY OF THE RESIN CANALS WERE EXAMINED ACCORDING TO THE RADIAL POSITION AT THREE DIFFERENT HEIGHTS; BOTTOM, BREAST HEIGHT DIAMETER AND AT THE BEGINNING OF THE TREE TOP. THE RESULTS SHOW THAT THE APICAL AND RADIAL VARIATION OF THE SIZE AND FREQUENCY OF RESIN CANALS APPEARED WEAKLY CORRELATED WITH THE INTENSITY LEVEL OF THE TREE RESIN-BLEEDING OF THE STANDING RADIATA PINE TREES.
