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...

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...

Nutrient cycling under 450-year-old Douglas-fir stands

Creator:: Abee, Albert
Abstract:: To investigate the movement of elements (N, P, k, Ca, and Mg) from the tree crowns by natural litterfall and leave wash, plots were established on six 450 year-old growth stands at the H. J. Andrews Experimental Forest. The following are the results of the data analyses. Elemental concentrations contained...

Influence of interplanted and pure stands of red alder (Alnus rubra Bong.) on microbial and chemical characteristics of a coastal forest soil in the Douglas-fir region

Creator:: Chen, Chi-sin
Abstract:: Chemical and microbial analyses were made at four seasonal intervals on soil horizons under red alder, conifers, and mixed alder-conifers at the Cascade Head Experimental Forest, established in 1937 by the U. S. Forest Service near Otis, Oregon. Microbial analyses showed that although plate counts of molds and bacteria fluctuated...

Phospholipids in germinating Douglas fir seed

Creator:: Chung, Wei-Kwo
Abstract:: Information concerning the kinds and composition of phospholipids in gymnosperm plants is negligible in the literature. Thus this study was undertaken to provide background knowledge for future comparative biochemical investigations. In this study, lipid was extracted by chloroform and methanol, and washed with distilled water to prevent the possible formation...
