Cytokinins are a group of plant hormones mediating cell division and
differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly
metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion
have been studied extensively. Zeatin metabolic enzymes may be utilized in studying the
regulation of...
A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay
processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the
77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of
¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...
Light-frame construction practices and materials have changed greatly
over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...
Nonalcoholic fatty liver disease (NAFLD) is characterized by an accumulation of neutral lipids in the form of triglycerides and cholesterol esters accounting for >5% of liver weight. Excess neutral lipids accumulate in large lipid droplets, i.e., macrosteatosis, displacing the nucleus of cells. Current theory suggests neutral lipid accumulation is the...
Results of 1977 and 1978 field trials of weed control research in horticultural crops are given in this report. These studies were conducted by the research staff at Corvallis.
Funds and supplies from the various companies of the agricultural chemical industry with products included in this report are gratefully acknowledged,
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
Land useable for livestock grazing in the western United States is
diminishing because of spreading municipalities, irrigation developments,
highway construction, recreational demands and withdrawals.
Concurrently, the demand for livestock and livestock products is increasing
because of a rapidly growing population. As a result, production
from the grazing land that remains...
The purpose of this study was to evaluate differences between winter wheat varieties in response to nitrogen fertilizer. Seven nitrogen fertilizer rate x variety factorial experiments were conducted in several environments. Dry matter and nitrogen yields at boot, soft dough, and harvest and grain yield components were measured. The yield...
