Seed Rain Patterns During Early Recovery On A Strip-Mined Site In Southwestern Wyoming, Hal W. Gordon
Undergraduate Honors Capstone Projects
Revegetating surface-mined soils of the western United States is a major problem facing natural resource managers today. The Surface Mine Reclamation and Conservation Act (SMRCA, Public Law 95-87) requires that the opera tor: "… establish on the regraded areas, and all other lands affected, a diverse, effective and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession at least equal in extent of cover to the natural vegetation of the area ... "
Historically, most of the coal produced in the U.S. came from the …

The Inhibition Of Germination Caused By The Lemma And Palea On Phalaris Arundinacea Seed, Nard Vee Allen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Reed canarygrass (Phalaris arundinacea) is adapted to low wet lands and survives flooding and periods of drought. Much of the valley bottom land of Utah is flooded during part of the year, yet some of this land is very dry late in the summer. This grass could become an important forage for Utah's valley bottom lands if stand establishment could be assured. Low germination percentages and long germination periods under field conditions often result in poor stands.
In most cases quick uniform germination is a decided advantage in establishing stands. Fall plantings have usually been more successful than …
Effect Of Root-Rot Upon Sugar-Beet Seed Production, Louis F. Nuffer
Effect Of Root-Rot Upon Sugar-Beet Seed Production, Louis F. Nuffer
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Due to considerable loss through root-rot of mother beets while in storage during the winter of 1918-1919 the Amalgamated Sugar Company asked advice in regard to planting beets which had decay lesions on them. Would the beets yield seed if planted? How much seed would these beets yield as compared with healthy beets? Would the seed produced be injured by having been grown on decayed beets? It was felt that an experiment carried out with the above questions in view would bring out many facts upon which to base conclusions in answering the questions of the Sugar Company.
