Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner Jan 2005

Response Of Sagebrush Steppe Species To Elevated Co2 And Soil Temperature, Melissa S. Lucash, Blake Farnsworth, William E. Winner

Environmental Science and Management Faculty Publications and Presentations

Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and physiology of species important to this ecosystem. Since the response of plants to elevated CO2 may be limited by environmental factors, soil temperature was also examined to determine if low soil temperatures limit CO2 response. To determine how CO2 and soil temperature affect the growth of species native to the sagebrush steppe, bottlebrush squirreltail [Elymus elymoides (Raf.) Swezey], Thurber needlegrass (Stipa thurberiana Piper), …

The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna Jan 2005

The Role Of Peroxidases In The Development Of Plants And Their Responses To Abiotic Stresses., Deborah Vicuna

Doctoral

Peroxidases and its effects on plants were analysed. Peroxidases are involved in many physiological processes in plants, involving responses to biotic and abiotic stresses and the biosynthesis of lignin. Liglin is a polymer responsible for rendering the plant stronger and more rigid and also making the cell walls hydrophobic. Peroxidases are involved in the polymerization of the precursors of lignin. They are also involved in the scavenging of Reactive Oxygen Species (ROS), which are partially reduced forms of atmospheric oxygen, highly reactive, and capable of causing oxidative damage to the cell. Peroxidases can be a source of hydrogen peroxide (H2O2) …

Effect Of Control Plot Density, Control Plot Arrangement, And Assumption Of Random Or Fixed Effects On Nonreplicated Experiments For Germplasm Screening Using Spatial Models, Boi Sebolai, Jeffrey F. Pedersen, D. B. Marx, D. L. Boykin Jan 2005

Effect Of Control Plot Density, Control Plot Arrangement, And Assumption Of Random Or Fixed Effects On Nonreplicated Experiments For Germplasm Screening Using Spatial Models, Boi Sebolai, Jeffrey F. Pedersen, D. B. Marx, D. L. Boykin

Department of Agronomy and Horticulture: Faculty Publications

Early generation selection experiments typically involve several hundred to thousands of lines. Various systematic and statistical techniques have been developed to increase effectiveness and efficiencies in such experiments, including the development and application of spatial statistical models. In this study, mixed model equations were used to provide least squares means (LSMEANs) and best linear unbiased predictors (BLUPs) and compare selection effectiveness and efficiencies to observed (Y) and true values in simulated experiments varying in size (10 X 10, 20 X 20 and 30 X 30 grids), control plots densities (0, 5, 10, 20, and 50%), control plot arrangements (high, medium, …

2005 Virginia Wildflower Of The Year: Bloodroot, Sanguinaria Canadensis, W. John Hayden Jan 2005

2005 Virginia Wildflower Of The Year: Bloodroot, Sanguinaria Canadensis, W. John Hayden

Biology Faculty Publications

Bloodroot is an herbaceous perennial that grows from a persistent, branched underground stem or rhizome. Early each spring, while the forest canopy is still bare, each well-developed rhizome tip produces one leaf and one flower stalk. The leaf is kidney-shaped in its overall outline, but it is also divided into a pattern of rounded lobes and sinuses, rendering a complex overall shape. At flowering time, bloodroot leaves form a loose vertically-oriented collar around the flower stalk with the bluish-green lower leaf surface forming the outside of the collar; as the season progresses, the leaves open flat and expand to their …

Colonisation Of Epipelic Diatoms On The Littoral Sediments Of İzmit Bay, Yelda Aktan, Güler Aykulu

Turkish Journal of Botany

Seasonal variations in the composition, density and diversity of the epipelic diatom assemblages were investigated monthly from March, 1999, to September, 2000, at 8 sampling sites chosen in the littoral of İzmit Bay. The main physical and chemical parameters, which affected species composition and density, were also measured on every sampling date. During the study period, 3 centric and 41 pennate diatoms were recorded in the epipelic diatom flora of the bay. Achnanthes Bory spp., Amphora exigua W.Greg. and Navicula tripunctata (O.Müll.) Bory were dominant in terms of frequency and density. In general, the bay showed a small species diversity …

Evaluation Of Diagnostic Reproductive And Vegetative Characters Among Tetraploid Triticum L. Species (Poaceae; Triticeae) In Iran, Navaz Kharazian, Mohammad Reza Rahiminejad

Turkish Journal of Botany

This study concerns the evaluation of 19 vegetative and reproductive characters (7 qualitative and 12 quantitative) among 45 accessions belonging to wild and cultivated tetraploid Triticum L. species: T. turgidum L., T. durum Desf., T. dicoccum (Schrank) Schrebler and T. dicoccoides (Koern. ex Aschers. et Graebn.) Aaronsohn, occurring in Iran. The results of this study show that T. turgidum is a distinct species from T. durum, and T. dicoccum showed high similarity to T. dicoccoides. The strong relationship between the latter pair of species may result from a high degree of gene flow between them. The diagnostic characters between T. …

Turkish Journal of Botany

The distribution of heterochromatin on the chromosomes of V. cracca L. subsp. cracca (2n = 14) and V. bithynica L. (2n = 14) was established with the aid of the C-banding technique. The chromosomes of both species have centromeric C-bands. When compared, prominent bands at the ends of the short arms on 4 chromosomes of V. cracca subsp. cracca were observed, while in V. bithynica only 1 chromosome had a prominent band at the end of the long arm. The C-banding patterns in the 2 species were different, and it was determined that heterochromatic regions were more dense on the …
