Untargeted metabolomic strategy was chosen to investigate as many small metabolites as possible in a collection of 13 varieties of conventionally grown spring and winter wheat and organic wheat (Triticum aestivum). Metabolites were separated by high-performance liquid chromatography on a reversed-phase column (RP–HPLC) coupled with electrospray ionization tandem mass spectrometry (ESI–MS/MS). T...

Flowering time is an important trait in wheat breeding as it affects adaptation and yield potential. The aim of this study was to investigate the genetic architecture of flowering time in European winter bread wheat cultivars. To this end a population of 410 winter wheat varieties was evaluated in multi-location field trials and genotyped by a genotyping-by-sequencing approach and candidate gen...

A yield estimation method by remote sensing was used to estimate the yield of winter wheat in Jiangsu province, China. The first step of this study was to extract the planting area of winter wheat from environmental satellite images and land -use map of Jiangsu province, meanwhile, correlation analyses were performed by using 8-day of composite Leaf Area Index (LAI) data from Moderate Resolutio...

Soil nitrogen cycling microbial communities and functional gene α−diversity indicate soil ecological functions potentials. Crop rotation plans affect fractions these indicators. We sequenced samples from four crop (fallow, winter wheat monoculture, pea-winter wheat-winter wheat-millet rotation, corn-wheat-wheat-millet rotation) in a long-term field experiment. examined how changed with regulate...

At least 16 nutrient elements are required by plants for growth and survival, but the factors affecting element concentration and their temporal evolution are poorly understood. The objective was to investigate i) element concentration pattern in winter wheat as affected by crop developmental stage and weather, and ii) whether, in the short term, element stoichiometry reflects the type of prece...

Inoculation of wheat seeds with two strains of Pseudomonas fluorescens (III107 and II21) and two strains of Bacillus mycoides (JC192 and K184) isolated from winter wheat roots, as well as with one strain of P fluorescens (ID13) isolated from oat roots, reduced the negative influence of Fusarium culmorum on winter wheat in a 28 day pot experiment. The bacterial strains (especially III107 and chi...

Mutation breeding is one of the breeding methods used successfully in durum wheat for selecting lines with increased agronomic values. This study was carried out to determine gamma rays effect and interaction between gamma-rays and the genotype of treated variety of winter wheat in mutations induction. We used physical mutagens: gamma-rays in doses 100, 150, 200, 250 Gy. Seeds of eight winter w...

The leaf chlorophyll content is one of the most important factors for the growth of winter wheat. Visual and near-infrared sensors are a quick and non-destructive testing technology for the estimation of crop leaf chlorophyll content. In this paper, a new approach is developed for leaf chlorophyll content estimation of winter wheat based on visible and near-infrared sensors. First, the sliding ...

Title of Document: INTEGRATED PEST MANAGEMENT OF FUSARIUM HEAD BLIGHT IN SOFT RED WINTER WHEAT. Elizabeth Reed, M.S., 2011 Directed By: Associate Professor Arvydas Grybauskas, Department of Plant Sciences and Landscape Architecture Fusarium head blight (FHB), caused by Fusarium graminearum, is a destructive disease of the soft red winter wheat grown in the Mid-Atlantic region. Management of FHB...

In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow system...
