Conservation of Rorippa columbiae : an evaluation of reintroduction potential through the study of germination ecology, propagation methods, and habitat requirements

Creator:: Kentnesse, Laura E.
Abstract:: Rare plant reintroductions are a critical conservation tool for the augmentation of diminishing populations, or re-establishment of extirpated populations. Analysis of reintroduction failures suggests that a sophisticated understanding of species biology, ecology, and habitat is essential for producing self-sustaining rare plant populations. This study sought to generate that background knowledge...

Genomic Resources for Phylogenetics, Species Delimitation, and Geographic Localization of Neotropical Tree Species Cedrela odorata L. (Meliaceae)

Creator:: Finch, Kristen N.
Abstract:: Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...

Pseudaleuria quinaultiana, a new genus and species of operculate ascomycete from the Olympic Peninsula

Creator:: Lusk-Newman, Demaris E.
Abstract:: Pseudaleuria quinaultiana gen. et sp. nova is described in English and Latin. P. quinaultiana is compared with Aleuria, Anthracobia Cheilymenia, Geopyxis, Humaria, lodophanus, Jafnea, Leucoscypha, Melastiza, Octospora, Pyronema, Scutellinia, Sphaerosporella, Tricharina, Morchella, Cookeina, Phillipsia, Pseudoplectania, Sarcoscypha, and Sarcosoma. Of these genera P. quinaultiana has hairs most similar to those found...

The genus Anthracobia Boudier (Pezizales, Ascomycetes)

Creator:: Larsen, Harold J.
Abstract:: A taxonomic revision of the genus Anthracobia Boudier is presented. The genus and eight included taxa are described and figured. A discussion of the taxonomic criteria used to delimit the genus and the species is included, and a key to the recognized taxa is given. Four imperfect states for included...

Comparative gibberellin relationships in tall and dwarf peas (Pisum sativum L.)

Creator:: Anderson, James David
Abstract:: Experiments were performed to determine whether a direct correlation exists between the growth rates of tall and dwarf peas grown either in the light or in the dark and endogenous gibberellin (GA) content. Three separate but related experimental approaches were utilized: (1) the determination of possible qualitative and /or quantitative...

Photoinduction of kaurene synthetase, an enzyme of the gibberellin biosynthetic pathway, during de-etiolation of pea seedlings

Creator:: Gomez-Navarrete, Gladys
Abstract:: Previous investigations have shown that the enzymes catalyzing the biosynthesis of the gibberellin-type of hormones from mevalonic acid in plants are compartmentalized in plastids. Moreover, the activity of one of the key enzymes in the biosynthetic sequence, kaurene synthetase, exhibits markedly enhanced activity when a dark-grown pea seedling undergoes de-etiolation...

Physiology of senescence of the shoot apex in Pisum sativum L.

Creator:: Ecklund, Paul Richard, 1941-
Abstract:: Shoot apex senescence is defined as the collective progressive and deteriorative processes which ultimately terminate the functional life of the shoot apex. Senescence of shoot apices of Pisum sativum L. 'Alaska' as measured by cessation of stem elongation was delayed by removal of flowers and by treatment with gibberellin A₃...

Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:: Garrett, Karen A.
Abstract:: Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...
