Forage production and utilization in relation to deer browsing of Douglas-fir seedlings in the Tillamook Burn, Oregon

Creator:: Crouch, Glenn Leroy, 1929-
Abstract:: The main objective of this investigation was to evaluate relationships between the production and utilization of forage and deer browsing of hand-planted Douglas-fir seedlings. A secondary purpose was to study some effects of selected physical and biological site factors on the survival and growth of fir seedlings. Field work was...

Vegetation and animal responses to grazing crested wheatgrass at three intensities and two seasons in southern Idaho

Creator:: Sharp, Lee Ajax
Abstract:: Land useable for livestock grazing in the western United States is diminishing because of spreading municipalities, irrigation developments, highway construction, recreational demands and withdrawals. Concurrently, the demand for livestock and livestock products is increasing because of a rapidly growing population. As a result, production from the grazing land that remains...

Forest associations and secondary plant succession in the southern Oregon coastal range

Creator:: Bailey, Arthur Wesley, 1938-
Abstract:: Forest associations, secondary succession, and relationships of plant communities to Roosevelt elk were investigated. Stratification of vegetation into ecological units and an understanding of secondary succession by habitat-type were a necessary first step in investigations into browsing of conifers by elk. The study was jointly conducted by the Oregon State...

The distribution, growth habits, and control of German velvetgrass (Holcus mollis L.) in Western Oregon

Creator:: Lee, William O., 1911-
Abstract:: A study was conducted on German velvetgrass (Holcus mollis L.), a weedy, rhizomateous perennial grass introduced in the United States in relatively recent years, The purpose of this study was to learn more about its distribution, growth habits, and control under conditions found in Western Oregon. German velvetgrass infestations of...

Influence of chelating agents on genetic recombination of Zea mays L.

Creator:: Ihrke, Charles Albert
Abstract:: Crossover frequencies for seven selected regions on five chromosomes of maize were measured to ascertain the effect of chelating agents on recombination. Ethylenediamine tetraacetic acid, EDTA, and dimethyl sulfoxide, DMSO, were used in three concentrations singly, and in all combinations. Plants heterozygous for for linked genes governing seed and seedling...

Techniques and media for excised tip culture of Vinifera cultivars

Creator:: Subhanij, Thiravira
Abstract:: Excised apical stem tips (2-5 mm) of grape cultivars grew well on Murashige and Skoog's (1962) medium for tobacco callus. Additions of glycine were not essential but gave a slight stimulus to growth. Naphthalene acetic acid slightly reduced growth rates but reductions were not statistically significant. Kinetin and coconut milk...

Meiotic chromosome behavior in two tall fescue (Festuca arundinacea Schreb.) genotypes and their sterile hybrid

Creator:: Vásquez, Raul Moreno
Abstract:: Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F ₁ hybrid plants that were sterile. One parent genotype (P₁) was from P. I. 234-906, introduced from Switzerland and the other (P₉) was an introduction from Turkey, P. I. 174-209. P₁ and...

Influence of range improvement practices on composition, production, and utilization of Artemisia deer winter range in central Oregon

Creator:: Urness, Philip J.
Abstract:: Recent emphasis on range improvement of sagebrush-bunch-grass types in Oregon has underscored the need for better understanding of their importance to deer winter range management. The objectives of this study were to evaluate the impact of various sagebrush control practices on the composition, production, and utilization of deer forage plants...
