Many investigators have suggested that current photosynthate
supply can limit adventitious root formation on leafy cuttings.
Accordingly, studies were undertaken to determine the effects of
altering photosynthesis and carbohydrate levels on adventitious root
formation by leafy cuttings of a number of different species.
Pea cuttings rooted at high CO₂ (1800...
A sensitive assay for the analysis of contaminating segments
in pseudorecombinants constructed from a seed-transmissible (CVM-Pg)
and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic
virus was developed using partial RNase T₁ digestion. Isolated
genomic RNA segments produced unique digestion patterns when 3'-
end labeled, treated with RNase T₁, and subjected...
Meadowfoam has been identified as a potential oilseed crop for
production on poorly drained soils in areas with cool, moist winters.
The effects of N fertilizer on meadowfoam (Limnanthes alba Benth.)
have been studied in Oregon and Maryland, but the results have not
been consistent with respect to the effects...
Seed-Lab, is a software system for managing seed laboratory information. It was developed at the Oregon State University Seed Testing Laboratory. Seed-Lab was built around a database development package Revelation, which provides its own programming language.
Seed-Lab shields the user from the complexities of database management by supporting menu driven...
Perennial ryegrass (Lolium perenne) - white clover
(Trifolium repens) hill-land pastures were grazed at
different times in the winter to study the effect of time
of winter grazing on plant response and forage production.
The same pastures were grazed by sheep once in early
December, January, February, March, or April...
Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...
Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...
China's Minqin Oasis once welcomed traders along the ancient Silk Road with rivers, lakes, and lush forests, yet today the region's farmland and grassland are increasingly being engulfed by the sands of the Gobi Desert. The severity of this incremental catastrophe for a declining population of 300,000 residents has brought...
This thesis explore the effects of China's Grassland Contract policy on sedentary and mobile Inner Mongolian pastoralists' attitudes towards cooperation, current grassland management practices, and the future viability of livestock herding in New Barag Right Banner, Inner Mongolia. Semi-structured interviews, a scaled survey instrument, and participant observation were carried out...
