Red sorrel (Rumex acetosella) also is known as sheep, horse, field, mountain, and cow sorrel or sour dock. This European weed grows throughout the Pacific Northwest under various soil and climate conditions.
Sweet corn is susceptible to various pathogenic Fusarium species and has been long known to be subject to early season diseases of seed rot and seedling blight as well as root rot and later season problems with stalk rot and ear rots. More recently, fields in the Willamette Valley of...
Both the structure and composition of naturally generated early-seral forests in the Pacific Northwest (PNW) can be profoundly different than that of more developed forest seres, especially in the period after a major disturbance but before conifers re-develop a closed canopy. While it is reasonable to suggest that the unique...
The root-lesion nematode Pratylenchus (hornet is one of the most important pests restricting productivity of wheat in the Pacific Northwest (PNW). It is laborious and difficult to use microscopy to count and identify the nematodes in soils. A SYBR Green I-based real-time polymerase chain reaction (PCR) assay was developed to...
Wheat breeders must effectively maintain and manage existing genetic diversity in order to continue the development of superior genotypes. It is therefore fundamental that the genetic relationships and diversity within the germplasm pools be thoroughly characterized and understood. Recently, DNA-based markers have provided powerful tools for genetic diversity analysis. This...
Stripe rust (Puccinia striiformis f. sp. tritici) and Septoria tritici blotch (Zymoseptoria tritici) are a constant and significant threat to wheat production, significantly reducing wheat quality and yield. Wheat is responsible for 20% of the world’s human calorie intake, and wheat production must increase to supply the demand of the...
Canopy structure has a significant impact on the canopy hydrology of
Douglas-fir forests in the Pacific Northwest (PNW). Whole canopy rainfall
interception was measured for young Douglas-fir forest and compared to an
old-growth Douglas-fir forest. The old-growth forest had significantly greater
canopy water storage capacity (5) and direct throughfall fraction...
The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...
Barley (Hordeum vulgare L.) has been cultivated for human consumption for thousands of years. However, most North Americans do not consume barley on a regular basis. In the last decade, there has been a renewed interest in barley production for human consumption. A number of quality traits estimate nutritional value...
In 1970, the Pacific Northwest (PNW) produced approximately 145,332,000 bushels of wheat (all types) with an average harvest value of over $220,000,000. White wheat comprised about 126,234,000 bushels of that total, about 87 percent. In recent years the financial circumstances, for several reasons, have deteriorated for many farmers and grain...
