Sinuous stem growth in a Douglas-fir (Pseudotsuga menziesii) plantation: growth patterns and wood-quality effects

Creator:

Spicer, R., Gartner, Barbara L., and Darbyshire, R. L.

Abstract:

Stem sinuosity is thought to negatively impact wood quality, but no studies have characterized its vertical and radial effects on wood properties. Here we study wood quality along the entire stem in 25-year-old plantation grown Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) trees (32 trees total) that had been scored...

Effects of live crown on vertical patterns of wood density and growth in Douglas-fir

Creator:

Gartner, Barbara L., North, Eric M., Johnson, G. R., and Singleton, Ryan

Abstract:

It would be valuable economically to know what are the biological triggers for formation of mature wood (currently of high value) and (or) what maintains production of juvenile wood (currently of low value), to develop silvicultural regimes that control the relative production of the two types of wood. Foresters commonly...
