The physiology of plagiotropic growth of rooted cuttings of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco]

Creator:

Starbuck, Christopher J.

Abstract:

Experiments were conducted to determine if the plagiotropic growth habit of rooted cuttings of Douglas-fir might result from a system favoring the accumulation of indoleacetic acid in the adaxial side of the shoot in response to vertical placement. Actively growing excised branch terminals were subjected to gravitational disorientation to determine...

An evaluation of the use of tarif tables in second growth Douglas-fir

Creator:

Marshall, David D.

Abstract:

The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...

Comparative development of a thinned and a natural Douglas-fir stand from 45 to 60 years of age

Creator:

Groman, William A.

Abstract:

An understanding of the dynamics of individual tree and stand growth, development, and structural patterns during the immature formative years of a commercial species is essential to determine correct thinning practices necessary to attain desired objectives. This study compared a natural, medium-site Douglas-fir stand and an adjacent similar stand released...
