The Effect Of Indoleacetic Acid And Related Chemicals On Growth Patterns Of Decapitated Bean Plants, Lewis V. Buchanan
The Effect Of Indoleacetic Acid And Related Chemicals On Growth Patterns Of Decapitated Bean Plants, Lewis V. Buchanan
Masters Theses
Bean plants were used to study effects of IAA and related chemicals on plant growth patterns. Plant apical growth tips were removed, eliminating apical donimance. Decapitated plants were treated in experimental groups with IAA, tryptophan, 5-hydroxy indoleacetic acid, serotonin, and melatonin. Two other groups served as controls, one cut, and one uncut.
Growth measurements were taken to determine if the treatments could effectively restore apical dominance. Cut control plants showed a loss of apical dominance, with decreased apical growth, and release of inhibition of axillary growth, when compared to the uncut group.
Tryptophan and meltonin treatments restored little or no …

A Population Study Of Three Iris (Iridaceae) Species Native To The Siskiyou Mountains In Southwestern Oregon And Adjacent California, Carol Anne Wilson
A Population Study Of Three Iris (Iridaceae) Species Native To The Siskiyou Mountains In Southwestern Oregon And Adjacent California, Carol Anne Wilson
Dissertations and Theses
The series Californicae is a natural grouping of Iris species native to Oregon, Washington and California. Natural and experimental hybridization is characteristic of the series which has led to confusing taxonomies for some species. Populations of species belonging to this series and found on the northwestern slopes of the Siskiyou Mountains cf southwestern Oregon and adjacent California were investigated. Methods used were numerical classification techniques for morphological characters including both discriminant and K-means cluster analyses and a chemotaxonomi c analysis of flavonoid pigments using thin layer chromatography.

Vegetation Analysis Of Three Zones Of Belmont Prairie, Dupage County, Illinois, Susan Eckert Ruta
Vegetation Analysis Of Three Zones Of Belmont Prairie, Dupage County, Illinois, Susan Eckert Ruta
Masters Theses
Belmont Prairie is located in Downers Grove, DuPage County, Illinois, and is one of the few preserves of a native tall grass prairie. It is located in the Morainal section of the Northeastern Morainal Division, and harbors over 100 species of native prairie plants which are typical of the community type. Three vegetation zones were sampled for species composition and both frequency and relative frequency. These areas are as follows: Dry mesic upland area, sedge meadow, and transitional area.
The upland dry mesic zone had diverse vegetation including forb and grass species such as Parthenium integrifolium, Silphium laciniatum, …
