Details are given in graphs of stand structure, annual dry-matter production, stand density, standing volume, and timber quality and size for each of the four methods. No statement is made as to which method is best.  astand density  aCryptomeria japonica spacing  aCryptomeria japonica stand density  aCryptomeria japonica thinning  aDensidade  aSistema de controle  aSpacing  aThinnings1 aDOI, K.1 aKATAOKA, H.1 aKATO, Y.1 aSAKAGUCHI, K.  tBulletin of The Government Forest Experiment Stationgn.209, p.1-76, 1968.
