We investigated the feasibility of using 6 Eucalyptus species grown in The University of Tokyo Forest, Arboricultural Research Institute, located in Shizuoka prefecture, for timber production by measuring key wood properties of each species. We measured radial growth rate (as half of the yearly diameter increment at breast height) at breast height. released strain of surface growth stress (RS). xylem density (XD) and microfibril angle (MFA) at the outermost part of the xylem at breast height, and heart-splitting at crosscutting of log in each tree. Growth rate varied according to species. E. signata E. andreana and E. piperita showed large values of RS and heart-splitting. XD and MFA differed significantly among species. Wood from E. smithii has potential as material for timber production because of high growth rate, high density and less heart-splitting.
