A Reappraisal Of The Relationship Between Free And Bound Coumarin In Melilotus, Francis A. Haskins, Herman J. Gorz
A Reappraisal Of The Relationship Between Free And Bound Coumarin In Melilotus, Francis A. Haskins, Herman J. Gorz
Department of Agronomy and Horticulture: Faculty Publications
In early work on coumarin in sweetclover, the assumption was made that the free form of the compound predominated in the intact plant. Subsequent investigations demonstrated the presence of bound coumarin in addition to free, and it was then thought that both forms were normally present. Recent work indicates that when suitable extraction procedures are used, virtually all the coumarin is obtained in the bound form. Such extraction procedures must provide for the rapid inactivation of β-glucosidase, thus preventing the hydrolysis of bound coumarin (apparently the glucoside of cis-o-hydroxycinnamic acid) during the extraction process. In the present study, inactivation …

Voluntary Associations Among Negroes In Lincoln, Nebraska, Ralph V. Thompson
Voluntary Associations Among Negroes In Lincoln, Nebraska, Ralph V. Thompson
Open Access Master's Theses (through 2010)
In almost every study undertaken, socio-economic status has been found to be a factor that is significantly related to memberships in voluntary associations. One of our major interests will be to discover whether or not such a relationship exists among the universe of Negro subjects from which the sample has been drawn. We will test such a relationship in this study.

Genetic, Developmental, And Within-Plant Variation In Free And Bound Coumarin Content Of Sweetclover, G. W. Schaeffer, Herman J. Gorz, Francis A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
Seeds of sweetclover contained a low level of both free and bound coumarin. An increase in both forms of coumarin occurred when seedlings were grown in the light, but no increase was found when they were kept in the dark. First- and second-year plants of Evergreen (CuB phenotype), W-7 (Cub), and W-31 (cu-) were sampled in the field at intervals throughout the 1959 growing season. Leaves, stems, and roots were assayed for free and total coumarin content. The level of free coumarin was highest in the leaves of plants of the CuB phenotype, with a …

Oviposition Response Of The Army Cutworm, Chorizagrotis Auxiliaris, To Different Media, K. P. Pruess
Oviposition Response Of The Army Cutworm, Chorizagrotis Auxiliaris, To Different Media, K. P. Pruess
Department of Entomology: Faculty Publications
Moths of the army cutworm, Chorizagrotis auxiliaris (Grote), (Lepidoptera: Noctuidae) responded ovipositionally to differences in soil color, texture, and depth. Number of eggs laid increased with amount of light reflected. A combination of loose surface over a solid substrate was required. A light-colored sand fulfilled all requirements and was preferred over soil. Soil was acceptable when a loose surface of correct depth was provided. Solid surfaces were refused.

Distribution Of Army Cutworm Larvae In Wheat And Barley Fields, K. P. Pruess
Department of Entomology: Faculty Publications
Populations of the army cutworm, Chorizagrotis auxiliaris (Grote), tended to be higher in winter barley than winter wheat planted side by side in the same field. Highest populations occurred in barley within 30 feet of the adjoining wheat. Distribution of larvae in linear 1-foot samples agreed closely with the Poisson. Practical application of these results are discussed.

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard
Papers in Ornithology
The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …

Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar
Mortality Of Eastern Brook Trout Caused By Plerocercoids (Cestoda: Pseudophyllidea: Diphyllobothriidae) In The Heart And Viscera, Glenn L. Hoffman, C. E. Dunbar
United States Fish and Wildlife Service: Publications
It is well known that migrating helminth larvae do a great amount of damage to the host. Often, however, the host is relatively large and the damage done by few larvae is not serious. When the host is very small the mechanical damage, at least, must be proportionately greater for each larva present. An unusual case of mortality of small brook trout (Salvelinus fontinalis) roughly 2 to 4 inches long was brought to our attention. Examination of the mortalities, as well as survivors, revealed relatively large diphyllobothrid larvae (fig. 1) in the chambers of the heart, liver, pericardial …

Notes On Sanguinicola Davisi (Trematoda: Sanguinicolidae) In The Gills Of Trout, H. S. Davis, Glenn L. Hoffman, E. W. Surber
United States Fish and Wildlife Service: Publications
In 1953 the late Dr. Davis recorded the presence of an unnamed trematode from the gill blood vessels of fingerling cutthroat trout (Salmo clarki) and fingerling steelhead trout (Salmo gairdneri) at the Alsea Hatchery and in yearling rainbow trout (Salmo gairdneri) at the Oakridge Hatchery, both of the Oregon State Game Commission. Subsequently, two blood flukes, Sanguinicola davisi and S. klamathensis, were described from trout by Wales (1958). The present species was determined to be S. davisi by one of us (GLH). This report supplements data reported by Davis (1953) and Wales (1958). …

Activities Of Acid Phosphatase, Peroxidase, And Polyphenolase In Etiolated Shoots From Control And Irradiated Maize Seeds, Francis A. Haskins, S. C. Downs
Department of Agronomy and Horticulture: Faculty Publications
Evidence is presented that enzymatic differences exist between etiolated shoots from appropriately irradiated maize seeds and shoots from control seeds. Differences in specific activities of acid phosphatase and peroxidase became apparent only when individual portions (first internode, coleoptile, and unexpanded foliage leaves) of the shoot were considered. Contributions of the three shoot portions to total activities of acid phosphatase, peroxidase, and polyphenolase also were studied, and irradiation-induced differences in the patterns of contribution were noted.

Assay Of Cis And Trans-O-Hydroxycinnamic Acids In Sweetclover Extracts, Francis A. Haskins, H. J. Gorz
Assay Of Cis And Trans-O-Hydroxycinnamic Acids In Sweetclover Extracts, Francis A. Haskins, H. J. Gorz
Department of Agronomy and Horticulture: Faculty Publications
Various investigations related to the biosynthesis of o-hydroxycinnamic acid in sweetclover require that simple, rapid methods of assay be available for both the cis isomer (coumarinic acid) and the trans isomer (o-coumaric acid). This report deals with two such methods, both of which represent refinements of a technique for the fluorometric assay of coumarin described in an earlier publication from t h i s laboratory a ask ins and Gorz, 1957). In one procedure, designatled method I, o-coumaric acid and total o-hydroxycinnamic acid are determined, and coumarinic acid is estimated by difference; while in the other procedure, method 11, coumarinic …
Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins
Department of Agronomy and Horticulture: Faculty Publications
SUMMARY
Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.
Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.
Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Genetic Control Of Coumarin Biosynthesis And Β-Glucosidase Activity In Melilotus Alba, G. W. Schaeffer, Francis A. Haskins, H. J. Gorz
Department of Agronomy and Horticulture: Faculty Publications
Two pairs of alleles, Cu/cu and g/5, are known to influence coumarin biosynthesis in Melilotus alba Desr. (Goplen e t al., 1957 ; Haskins and Gorz, 1957). Young leaves from CuCuBB plants characteristically contain substant i a l akounta of both free and bound co-in, CuCubb leaves are high in "coumarin" but virtually a l l the substance is in the bound form, and cucuBB and cucubb leaves are low in both forms. Lt has been suggested that the gene is involved in the formation of bound coumarin from coumarin precursors and that the gene is concerned with the conversion …
