A Synopsis Of The Ferns And Fern Allies Of Nebraska, With Maps Of Their Distribution, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland

School of Biological Sciences: Faculty Publications

An annotated list and county-by-county distribution maps are presented for the 32 species of ferns and fern allies native to Nebraska, based upon field and herbarium studies and critical evaluation of the literature. Native to the state are Isoetes melanopoda, Selaginella rupestris, five species of Equisetum, and 25 species in 18 genera of ferns. Three native species are here verified for the first time, based upon recent collections: Matteuccia struthiopteris var. pensylvanica, Ophioglossum engelmannii, and Pellaeaglabella ssp. glabella. Isoetes melanopoda was rediscovered in 2000, the first record since 1941. Rejected are published reports …

Origin And Conservation Genetics Of Threatened Ute Ladies’-Tresses, Spiranthes Diluvialis (Orchidaceae), Allen L. Szalanski, Gerry Steinauer, Richard Bischof, Jessica Lynn Petersen Jan 2001

Origin And Conservation Genetics Of Threatened Ute Ladies’-Tresses, Spiranthes Diluvialis (Orchidaceae), Allen L. Szalanski, Gerry Steinauer, Richard Bischof, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

The Ute ladies’-tresses, Spiranthes diluvialis, is listed as a threatened orchid in west-central United States by the Federal government. Information on its origin and patterns of genetic variation is needed to develop effective conservation strategies for this species. DNA sequencing and polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) was used to evaluate genetic variation and structure of 23 populations of S. diluvialis. In addition, four congeneric species were analyzed to determine possible origins of the putative allotetraploid S. diluvialis. DNA sequencing and PCR-RFLP analysis of the nuclear ribosomal internal transcribed spacer (ITS) and mitochondrial and chloroplast DNA …


Aquatic Plants Of Nebraska, Michael P. Gutzmer, Robert B. Kaul Jan 2001

Aquatic Plants Of Nebraska, Michael P. Gutzmer, Robert B. Kaul

University of Nebraska State Museum: Programs Information

More than 100 species of aquatic plants grow in Nebraska. Some are entirely submersed for their whole lives, others produce floating leaves and flowers, and still others stand upright, with only their lower stems in water. Examples of these are shown here in this publication.

Vigorous and diverse colonies of aquatic plants are usually a sign of healthy and stable aquatic environments. In fact, the plants themselves stabilize the shorelines, underwater soils, and water chemistry. Waters rich with aquatic plants are rich with aquatic animals and waterfowl, which find cover, breeding habitat, and abundant food. Non-alkaline waters have more aquatic …

Department of Agronomy and Horticulture: Faculty Publications

Twenty-three entries of grain sorghum (Sorghum bicolor (L.) Moench), including eight inbred lines (five males and three females) and 15 hybrids, were evaluated to determine the proportion of γ, αII, and β-αI-kafirins and their association with contents of crude protein, fat, and starch; protein digestibility; in vitro dry matter disappearance; and seed weight. The male lines included three normal-seeded lines (TX2737, TX435, and P954063) and two large-seeded lines (Eastin1 and PL-1). Female lines consisted of three common U.S. seed parent lines (Wheatland, Redlan, and SA3042). The lines and their hybrids were grown under dryland conditions at two locations in …


Genomic Regions That Underlie Soybean Seed Isoflavone Content, K. Meksem, V. N. Njiti, W. J. Banz, M. J. Iqbal, My. M. Kassem, David L. Hyten, J. Yuang, T. A. Winters, D. A. Lightfoot Jan 2001

Soy products contain isoflavones (genistein, daidzein, and glycitein)that display biological effects when ingested by humans and animals, these effects are species, dose and age dependent. Therefore, the content and quality of isoflavones in soybeans is a key to their biological effect. Our objective was to identify loci that underlie isoflavone content in soybean seeds. The study involved 100 recombinant inbred lines (RIL)fr om the cross of ‘Essex’ by ‘Forrest,’ two cultivars that contrast for isoflavone content. Isoflavone content of seeds fromeach RIL was determined by high performance liquid chromatography (HPLC). The distribution of isoflavone content was continuous and unimodal. The …

Seed Physiology, Production & Technology: Germination, Emergence, And Yield Of 20 Plant-Color, Seed-Color Near-Isogenic Lines Of Grain Sorghum, Jeffrey F. Pedersen, J. J. Toy

Although there is growing demand for sorghum [Sorghum bicolor (L.) Moench] with white seed and tan plant color, there is limited information on the overall agronomic fitness of sorghum with these characters. A set of experiments was conducted to evaluate the combined effects of plant color and seed color on sorghum germination, emergence, and agronomic performance. Twenty near-isogenic lines with red seed/tan plant (RT), red seed/purple plant (RP), white seed/ tan plant (WT), white seed/purple plant (WP) phenotypes were tested under field and laboratory conditions. Plant color X seed color interactions were not significant. Purple plant color phenotypes had higher …
