Oregon is a gardener’s dream. Our varied climates and mild conditions allow us to showcase a wide variety of plants from around the world. In fact, nursery crops are Oregon’s number one agricultural commodity.
Unfortunately, a few plants used in gardens and landscapes cause serious
ecological harm by ‘jumping the...
Hydrogen cyanamide (CY) has been used to break rest
in temperate crops, but levels used to overcome rest are
sometimes toxic to plants. The rest breaking effect of CY
is thought to involve peroxide metabolism. Inhibition of
catalase by CY has been proposed as a mechanism for
overcoming dormancy in...
Hydrogen cyanamide (CY) induced earlier budbreak, more
uniform and a higher percentage of budbreak in resting
poplar (Populus alba x P. gradidentata, NC 5339) plants.
However, it was phytotoxic to poplar when applied at 0.5 M
or higher concentrations. Percent budbreak increased and
percent dieback decreased when poplar plants were...
The leaching of water soluble phenolic compounds from
cold stressed Rhododendron leaves was found to be a reliable
indicator of tissue damage. In sublethally stressed leaf
tissues, more and novel phenolic compounds appeared and were
hypothesized to be precursors of cell wall components such
as lignin and suberin. Subsequent radiolabeling...
The purpose of this paper is to identify significant storm events
occurring over a ten year period along the Oregon coast. The findings will be
used in a larger research framework to build an information base that looks into
the role of climatic forcing on coastal erosion and sediment transport...
This report frames the debate over studded tires in terms of economic principles of marginal cost pricing and efficient resource allocation. In the absence of a user tax, the pavement damage caused by studded tires results in inefficient pricing because social costs associated with the damage are excluded from the...
