Study on Selection of Pulpwood Clone of Chinese Fir

  • Received Date: 2004-04-29
  • Based on 16 years' studies, this paper explored and made clear the change laws of volume, dry matter of individual tree, fibre weight of individual tree, fibre length, fibre width, ratio of fibre length to width,fibre content and density of timber and the correlation of these properties.There were greatly obvious discrepancies among the properties of different clones,both fibre length and fibre width were not affected by site.The contribution rates of volume,fibre percentage and density of timber to fibre capacity of individual tree were respectively 61.7%,22.6%,15.7%.The hereditary capacity was in the range of 0.510.68.By comparison,12 clones of long-fibre,4 of medium-fibre and 4 clones suitable for poor site condition were selected.

Abstract: Based on 16 years' studies, this paper explored and made clear the change laws of volume, dry matter of individual tree, fibre weight of individual tree, fibre length, fibre width, ratio of fibre length to width,fibre content and density of timber and the correlation of these properties.There were greatly obvious discrepancies among the properties of different clones,both fibre length and fibre width were not affected by site.The contribution rates of volume,fibre percentage and density of timber to fibre capacity of individual tree were respectively 61.7%,22.6%,15.7%.The hereditary capacity was in the range of 0.510.68.By comparison,12 clones of long-fibre,4 of medium-fibre and 4 clones suitable for poor site condition were selected.
