Effects Of Temporary Par Reduction On The Seagrass Amphibolis Griffithii (Black) Den Hartog, Paul R. Mackey Jan 2004

Effects Of Temporary Par Reduction On The Seagrass Amphibolis Griffithii (Black) Den Hartog, Paul R. Mackey

Theses : Honours

Declines in seagrass health and distribution are commonly caused through human induced reductions in the availability of photosynthetically active radiation (PAR). These reductions can result from a variety of human-induced perturbations, including channel dredging. The impetus for the research was driven by the broad-scale degradation of the ecologically important southern-Australian endemic seagrass Amphibolis griffithii (Black) den Hartog in Champion Bay, Geraldton, Western Australia. The study investigated the affects of reduced PAR on A. griffithii and identified responses that may be useful in developing management triggers to minimise the impact of PAR limitation events. The study was carried out during late …

Molecular Mapping And Identification Of Soybean Fatty Acid Modifier Quantitative Trait Loci, D. L. Hyten Jr., Vincent R. Pantalone, Arnold M. Saxton, Michael E. Schmidt, Carl E. Sams

Department of Agronomy and Horticulture: Faculty Publications

Altering FA content in soybean [Glycine max (L.) Merr.] oil for improved functionality is a research goal of many soybean breeders. Several of the genes that alter palmitic, stearic, oleic, linoleic, and linolenic acids are modifier genes with small effects, causing these FA traits to act as quantitative traits. The objective of this study was to identify modifier FA quantitative trait loci (QTL) in soybean. A recombinant inbred line population was created from two prominent ancestors of currently avail-able U.S. cultivars (Essex and Williams) and grown in five environments. One hundred simple se-quence repeat markers spaced throughout the genome …

Predicting Phenological Development In Winter Wheat, Qingwu Xue, Albert Weiss, P. Stephen Baenziger Jan 2004

Predicting Phenological Development In Winter Wheat, Qingwu Xue, Albert Weiss, P. Stephen Baenziger

Department of Agronomy and Horticulture: Faculty Publications

Accurate prediction of phenological development is important in the winter wheat Triticum aestivum agroecosystem. From a practical perspective, applications of pesticides and fertilizers are carried out at specific phenological stages. In crop-simulation modeling, the prediction of yield components (kernel number and kernel weight) and wheat-grain yield relies on accurate prediction of phenology. In this study, a nonlinear multiplicative model by Wang & Engel (WE) for predicting phenological development in differing winter wheat cultivars was evaluated using data from a 3 yr field experiment. In the vegetative phase (emergence to anthesis) the daily development rate (r) was simulated based on the …

Life Strategies And Adaptations In Bryophytes From The Near And Middle East, Harald Kürschner Jan 2004

Life Strategies And Adaptations In Bryophytes From The Near And Middle East, Harald Kürschner

Turkish Journal of Botany

A review article on life strategies and ecomorphological adaptations (xerothalloid and xeropottioid life syndromes) of bryophytes is given, based on the hitherto known and analysed terrestrial, saxicolous and epiphytic communities of the Near and Middle East. The examples given impressively demonstrate common adaptive trends that arise convergently but independently in unrelated taxa when they evolve under similar habitat conditions. These functional types are important for the establishment, habitat maintenance and dispersal of species and indicate the relationships between site ecology, niche differentiation and species evolution. Their differentiation is a prime example of parallel evolution.

Possibility Of An Information System On Plants Of South-West Asia With Particular Reference To The Turkish Plants Data Service (Tubives), M. Teki̇n Babaç Jan 2004

Possibility Of An Information System On Plants Of South-West Asia With Particular Reference To The Turkish Plants Data Service (Tubives), M. Teki̇n Babaç

Turkish Journal of Botany

For quick and accurate access to information about a flora of a country it is becoming increasingly important to develop databases. Databases developed and provided by international organisations are expensive to use and difficult to maintain without outside help. It is therefore important for developing countries to develop their own plant databases best suited to their requirements. One such example is the Turkish Plant Data Service (TUBIVES), designed by Turkish systematists. This database is described with some samples, and the possibility of creating a South-West Asian Plants Information Service (SWAP-IS) is briefly discussed.

Value Of Trichome Characteristics For The Separation Of Bifurcating Hairy Astragalus L. (Fabaceae) At The Sectional Level, Farrokh Ghahremaninejad Jan 2004

Value Of Trichome Characteristics For The Separation Of Bifurcating Hairy Astragalus L. (Fabaceae) At The Sectional Level, Farrokh Ghahremaninejad

Turkish Journal of Botany

The attachment of hairs in sections of Astragalus L. may be either basal or lateral (bifurcate). This study focuses on Astragali with bifurcating hairs in the Old World (subgenus Cercidothrix Bunge). In this study, it appears that the ratio of hair arm length, and hair form and length are usually stable at the sectional level. The proposition of uniting some sections based on morphological characters is confirmed by hair characters; for example, uniting sections Tamias Bunge, Acantherioceras Rech. f. and Pseudoerioceras Ulzijchutag with Erioceras Bunge. The most important characters in the separation of the sections are macromorphological, but hair characters …
