Mechanisms of resistance in broccoli, Brassica oleracea italica to the garden symphylan, Scutigerella immaculata (Newport)

Creator:: Simagrai, Montri
Abstract:: Studies were conducted on the mechanisms contributing to resistance in broccoli, Brassica oleracea italica, to the garden symphylan, Scutigerella immaculata (Newport). Differences in resistance to symphylan injury were shown between five selected broccoli cultivars. The hybrid cultivars, Crusader, Green Duke and Bravo, showed a higher level of resistance to symphylans...

Stratigraphy and genesis of soils from volcanic ash in the Blue Mountains of Eastern Oregon

Creator:: Rai, Dhanpat, 1943-
Abstract:: Investigations were conducted to (1) determine the original pattern of deposition and thickness of ash in the Ochoco and Blue Mountain areas of Oregon, (2) determine if discontinuities exist in the parent material of these soils, (3) determine the degree of mixing of ash with other materials and evaluate reworking...

CER and leaf characteristics of four tall fescue (Festuca arundinacea Schreb.) selections differing in forage yield

Creator:: Cohen, Cynthia Joy
Abstract:: Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...

Comparative study of some soil characteristics of grassland and forest/grassland transition in western Oregon

Creator:: Ezenwa, Matthew Ikechuku Sunday
Abstract:: Vegetation as a soil-forming factor was studied under forest transition and grass while attempting to keep other soil forming factors constant in the western part of the Willamette Valley, Oregon. The physiographic units consist chiefly of the interior foothills and slopes formed from an old basaltic flow with some interspersed...

Factors associated with the social climate of single-sex and coeducational residence halls, cooperatives, fraternities, and sororities, on the Oregon State University campus

Creator:: Frichette, Steven Roger
Abstract:: The purpose of this research was to examine factors associated with the social climate of single-sex and coeducational residence halls, fraternities, sororities, and cooperatives on the Oregon State University campus. The primary sources of data for this study were student responses to the ten subscales of the URES Form R,...

Inheritance and association of earliness and grain yield in four winter x spring wheat crosses (Triticum aestivum L. em Thell.)

Creator:: Firat, Ahmet Ertug
Abstract:: Parental and segregating populations derived from four winter x spring wheat crosses were investigated to obtain information concerning the inheritance and association of earliness, grain yield and yieldrelated traits. Feasibility of selecting in early generations for these characteristics was also evaluated. Four winter wheat cultivars (Hyslop, Yamhill, Bezostaia 1, and...

Physical structure and reconstitution of chromatin core particles

Creator:: Tatchell, Kelly George
Abstract:: The nucleosome appears to be the basic structural unit of the eukaryotic chromosome. The usual nucleosome preparation, isolated from a micrococcal nuclease digest of nuclei, is heterogenous in DNA length and protein composition with some particles containing spacer DNA and associated protein. This heterogeneity complicated physical and reconstitution studies. As...
