The feasibility of using diploid by tetraploid crosses to obtain triploid hops (Humulus lupulus L.)

Creator:: DeNoma, Jeanine Streeter
Abstract:: The hop (Humulus lupulus L.) is a dioecious, diploid (2n=2x=20) species. Triploid hops (2n=3x=30) are easily obtained from tetraploid by diploid crosses and are preferred because of their natural seedlessness and increased vigor. The female inflorescence is used for flavoring beer. Because brewers require product consistency, the brewing characteristics of...

Vernalization requirement studies with Pacific Northwest wheats

Creator:: Baloch, Dost M.
Abstract:: Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...

Genetic analysis of malt extract and grain yield in a spring barley (Hordeum vulgare L.) cross

Creator:: Ozdemir, Ergun
Resource Type:: Masters Thesis

The stratigraphy, hydrology, and redoximorphic character of the Jackson-Frazier wetland

Creator:: D'Amore, David V.
Abstract:: Transitional areas between upland and aquatic habitats, commonly known as wetland, were once viewed as unproductive areas and were drained for farming or pasture. Wetlands are now accepted as significant ecological resources, and their protection is a mandate of federal, state, and local land managers. Due to the diversity of...

Deep soil nitrogen survey, Lower Umatilla Basin, Oregon

Creator:: del Nero, Zachary Augustus
Abstract:: Soils of 49 agricultural and 2 "native condition" sites in the Lower Umatilla Basin, Oregon were sampled for nitrate-nitrogen, ammonium-nitrogen, chloride, and pH beginning in Fall of 1992. Several sites were sampled in Spring and Fall 1993 in order to indicate movement or loss of residual soil nitrogen over time....

Inorganic nitrogen and soil biological dynamics in cover crop systems

Creator:: Kauffman, Susan Muna
Resource Type:: Masters Thesis

A comparison of vegetation suppression and sod-seeding methods using perennial ryegrass in renovation of non-irrigated permament pastures in western Oregon

Creator:: Neumeister, John H.
Abstract:: Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
