Knot number, size and distribution differences in sugi trees (Cryptomeria japonica D.Don) among four stands by different pruning procedures
2005
Nakano, T. | Hirakawa, Y.
The knot number, size and distribution of forty-year-old sugi trees (Cryptoperia japonica D.Don) were examined in four stands which had each been pruned differently: Kuma-sugi (early pruning), Gero-sugi (late pruning), Urasebaru-sugi (no pruning) and Aya-sugi (no pruning). In the stand which was pruned early, the non-knot region was wider and the square-sawn timber having no knot in suface were about 5cm smaller in diameter than unpruned trees. Additionally, annual ring widths of early pruned trees were all within 2-4mm of each other at all measured heights.
