Edible tree nut and peanut industries are important agricultural
industries in the United States. Major tree nuts produced
domestically are almonds, filberts, pecans,and walnuts. The United
States imports and exports some quantities of these tree nuts and
peanuts, but at the same time the U.S. imports cashew, brazil,
pignolia, and...
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...
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...
This study centered upon two objectives. First, to demonstrate and apply a statistical method, the transfer function, and to test its usefulness in regional economic modeling and regional impact ana1ysis; and second, to obtain a better understanding of the causal relationships among total employment, government employment, lumber and wood products...
Oxides of post-transition metals often show unique structures and properties due to the presence of lone pair electrons and the diffused s orbitals. The present work focuses on synthesis and characterizations of oxides containing Te, a heavy post transition metal.
New series of pyrochlore oxides of the formula Cs(M,Te)₂O₆ (M...
Thinning has the potential to increase structural diversity of managed forests for wildlife. During 1994-1996, I conducted experimental and observational studies using pitfall trapping to assess short-term and potential long-term effects of thinning on abundance and reproduction of forest-floor vertebrates in Douglas-fir (Pseudotsuga menzeisii) forests of the Oregon Coast Range....
Endogenous concentrations of indole-3-acetic acid (IAA) and cytokinins were compared to the tendency for plagiogravitropjc growth in rooted stein cuttings of Douglas-fir. A chromatographic method was developed for
the purification and quantitation of trace levels of IAA. Two elutions with reverse-phase high performance liquid
chromatography (HPLC) using a fluorescence detector...
