Interactions Of Arbuscular Mychorrhizal Fungi And Bacterial Endophytes On Disease Resistance Of Common Root Pathogens In Wheat, Janice L. Eibensteiner
Interactions Of Arbuscular Mychorrhizal Fungi And Bacterial Endophytes On Disease Resistance Of Common Root Pathogens In Wheat, Janice L. Eibensteiner
Electronic Theses and Dissertations
Arbuscular mycorrhiza, a symbiosis between plants and fungi, help plants to capture nutrients such as phosphorus (P), nitrogen (N) and other micronutrients from the aggre in exchange for up to 20% of the fixed carbon (C) from the plant. In addition, arbuscular mycorrhizal (AM) fungi can improve the resistance against abiotic (drought, salinity), and also biotic (pathogen) stresses. Bacterial endophytes promote plant growth and yield by fixing N2 from the atmosphere, assimilating N and transfer it to the plant. Bacterial endophytes can also solubilize phosphate and stimulate plant defense responses, suppressing pathogens. The host plant provides sucrose and a favorable …
Efficacy Of Synthetic And Biopesticides On Bacteria Leaf Streak Management And Influence Of Cultivar And Environment On Epiphytic Bacteria Diversity On Wheat Seeds, Marilen Nampijja
Electronic Theses and Dissertations
Wheat (Triticum aestivum) is the most important staple food for over two billion people, or 36% of the world population. The United States ranks 4th in the world for wheat production. However, wheat production is faced by both biological and non-biological constraints. Among the biological constraints, diseases play a big role in limiting wheat production with estimated yield losses ranging from 20% to 40%. Bacterial leaf streak (BLS) of wheat caused by Xanthomonas translucens pv undulosa (Xtpvu) is one of the major bacterial diseases affecting the wheat production in most wheat growing regions in the USA. In recent years, it …
Quality Evaluations Of Hard Red Spring Wheat Grown In South Dakota, Lance Merrick
Quality Evaluations Of Hard Red Spring Wheat Grown In South Dakota, Lance Merrick
Electronic Theses and Dissertations
Hard Red Spring Wheat (HRSW; Triticum aestivum L.) is characterized by generally high protein content and excellent baking and milling performance. The ability for millers, bakers, and other end-users of wheat to properly and cheaply produce food products with uniformity is dependent on the quality consistency of wheat produced by breeders and farmers. Determining how production years and locations influenced enduse quality traits will assist breeders, agronomists, and growers, in understanding which hard red spring wheat (HRSW; Triticum aestivum L.) varieties are least susceptible to quality fluctuations, and therefore, most desirable to end-users. In order to determine which varieties were …
