Phylloplane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L.), hop (Humulus lupulus L.), mint (Mentha piperita L.) and tomato (Lycopersicon esculentum Mill.)

Creator:: Sontirat, Pattana
Abstract:: Phyllopane microorganisms on the leaf surfaces of bean (Phaseolus vulgaris L. ), hop (Humulus lupulus L. 'Fuggle-H'), mint (Mentha piperita L. 'Mitcham') and tomato (Lycopersicon esculentum Mill. ) has been observed by cultural methods. A leaf impression method was used to examine both actively growing and inactive propagules present on...

A chemosystematic study of the phylogenetic position of Arabidopsis thaliana (L.) heynh. (Brassicaceae) employing numerical methods

Creator:: Kaplan, Hesh J.
Abstract:: The Brassicaceae, Mustard Family, is a well marked natural family, whose tetramerous flowers, tetradynamous stamens, and distinctive bi- carpellary fruits, clearly distinguish it from related families. It is a large family of some 3, 000 recognized species and over 300 genera. Although numerous attempts have been made over the past...

Fescue taxonomy in the Pacific coast states

Creator:: Wilson, Barbara L.
Abstract:: Accurate taxonomy is essential to preservation and management of native grasses. Four problems in fescue taxonomy were investigated: the identity of the native fescue that dominates western Oregon and Washington prairies, the relationship of native Festuca roemeri to closely related grasses, the status of F. howellii and F. washingtonica, and...

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...

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

A revision of Juncus subgenus genuini (Juncaceae) in the Pacific states

Creator:: Lint, Harold LeRoy
Abstract:: A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...

Taxonomy of Phacelia section Miltitzia (hydrophyllaceae)

Creator:: Halse, Richard R.
Abstract:: A systematic study was made of the species comprising Phacelia section Miltitzia. These species, which are commonly found in the Great Basin physiographic province of western North America, are distinguished from other members of Phacelia by their yellow, marcescent corollas and their transversely corrugated seeds. This project utilized morphological, cytological,...

Sweet corn decline syndrome in Oregon's Willamette Valley

Creator:: Hoinacki, Elisabeth V.
Abstract:: For the past several years vegetable growers in Oregon's Willamette Valley have experienced reduced yields in their sweet corn plantings. We conducted studies to 1) describe the symptomology and etiology of the disease, 2) test a root rot rating system we developed to evaluate factors in the disease syndrome, and...
