Ecological consequences of root grafting in tabonuco (Dacryodes excelsa) trees in the Luquillo Experimental Forest, Puerto Rico



Ecological consequences of root grafting in tabonuco (Dacryodes excelsa) trees in the Luquillo Experimental Forest, Puerto Rico



Biotropica 25(1): 28-35



Over 60% of stems and basal area of Dacryodes excelsa occurred in clumps of trees interconnected by root grafts in the subtropical wet forest of Puerto Rico. Self and intraspecific grafting were extensive, while interspecific grafting was uncommon in this species. Seedlings and saplings did not show grafting. Grafted trees were taller and had a smaller ratio of crown to diameter at breast height. Hurricane damage was significantly greater in isolated trees than in those in clumps.
