Distribution of light within the crown of an open-grown Douglas-fir

Creator:: Ungs, M. J. (Michael J.)
Abstract:: A systematic investigation was made of the distribution of short wave radiation within the crown of an open-grown Douglas-fir tree. The study tree was 23 years old, 14 meters tall and had a maximum crown diameter of about ten meters. Global radiation was measured every 15 cm along eight different...

A study of several anatomical variables in relation to their effect on tensile strength of Douglas-fir

Creator:: McMinimy, Lawrence Otto
Abstract:: A microscopic study was conducted on specific gravity wafers taken from standard tensile strength specimens of young growth Douglas-fir. Samples were studied to determine the effect of variables such as percent summerwood, fiber length and fibril angle on tensile strength of Douglas-fir. The sample specimens were picked so effects of...

Effect of snowbrush on the establishment and growth of Douglas-fir seedlings

Creator:: Scott, William
Abstract:: Six, recent clear cut areas were selected in the Douglas-fir zone of the Western Cascade Range of Oregon to determine the environmental and nutritional effects that snowbrush has on the establishment and growth of Douglas-fir seedlings. One thousand eighty milacre sample plots on the six clear cuts were used to...

Root initiation and elongation in Douglas-fir, Pseudotsuga menziesii (Mirb.) franco, stem cuttings as related to bud and cambial activity

Creator:: Bhella, Harbans Singh
Abstract:: The relation of bud and cambial activity to root initiation and elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stem cuttings was studied through two successive growth cycles. Stem cuttings of current season's growth were taken periodically from field-grown Douglas-fir trees to determine: (1) origin and development of root initials; and...
