Dormancy in seed of Festuca arundinacea Shreb. was
studied.
The
acquisition of dormancy during seed maturation was
examined and the
effect on dormancy relief by chemical and
physical treatments was
determined.
The implication of endogenous growth inhibitors
in
dormancy imposition and maintenance was assessed.
Germination responses
to temperature and growth...
Evaluation of the safety hazards along a highway is usually
performed at specific locations and on known hazards. But, it is also
important to find any unrecognized hazards and their locations. Many
factors contribute to accident potential, and the combined effect of
several of them could produce a hazard that...
The spatial organization of farm units in Polk and Linn counties
in the mid-Willamette Valley has undergone significant change over
the past 30 years. Whereas most study areas operations in the
1930's and 1940's consisted of small family owned farms with contiguous
land bases, present mid-Willamette Valley units vary considerably...
The physical characteristics and spatial location of
land are hypothesized to be significant inputs to its
valuation. This research evaluates the influence of
locational, economic, and physical site variables on the
assessed value of real property.
Evaluation of such influences is based on a stratified
systematic sample of land parcels...
Objectives
The research project from which this publication stems, "Institutional Structures for Improving Rural Community Services," proposed to identify those leadership and organizational variables which might be altered to improve the institutional structures for providing public services to rural areas. Implicitly, the project proposal recognized that many declining rural communities...
Alnus rubra (Bong. ) seedlings were grown in sand culture and
irrigated with nutrient solution containing CdCl₂
ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks
with 50 and 100 mg CdCl₂
per liter of nitrogen-free nutrient solution
decreased in situ nitrogenase...
A prototype deep ocean nuclear moisture meter was developed
based on the detection of epithermal neutrons backscattered from
marine sediment molecules. Development consisted of choosing a
source, a detector, containment materials, and associated counting
equipment, followed by the construction and calibration of the probe.
Thermal neutron response of the probe...
