Identification and generation of new germplasms in barley with increased tolerance to waterlogging
… of barley varieties that are more tolerant to waterlogging has become an important research focus. The N-end rule protein degradation pathway has been shown to play an important role in the response of plants to flooding in Arabidopsis thaliana. Based on sequence similarities, N-end rule …

Dissection of Soil Waterlogging Tolerance in Soft Red Winter Wheat using Genomic Approaches
… and breeding lines were subjected to soil waterlogging stress over two seasons at Stuttgart, AR and St. Joseph, LA, US. Total concentrations of P, K, Ca, Mg, Mn, Fe, Al, B, Cu, Na, S and Zn were determined in wheat shoots post-waterlogging using inductively coupled plasma spectroscopy. …

Quantitative Trait Loci Associated with Waterlogging Tolerance in a Soft Red Winter Wheat Mapping Population
<p>Waterlogging is caused when water stays superficially in the soil for an extended period of time, creating an anaerobic environment which decreases plant growth and grain yield at maturity. Despite the impact of waterlogging on wheat production both globally and in the southeastern U.S., very …

Association Mapping for Elemental Concentration Resulting from Vegetative Stage Soil Waterlogging Stress in Wheat (Triticum aestivum L.)
<p>Soil waterlogging (WL) affects wheat production worldwide, including the southern of the U.S. Little is known about the genetics of tolerance mechanisms to WL, particularly of potentially toxic elements such as aluminum, iron and sodium. The objectives of this study were to use association …

Using targeted phenomics and environmental proxies to understand Phytophthora medicaginis and Phytophthora root rot resistance in Australian chickpea
… medicaginis. Yield penalties are exacerbated by waterlogging resulting in partial or complete crop losses with few control options. Higher levels of PRR resistance have been identified in wild Cicer species but are associated with undesirable traits due to genetic linkage drag. Understanding the …

Hyperspectral and Thermal Remote Sensing of Plant Stress Reponses to Oil Pollution.
… and two typically encountered plant stresses of waterlogging and water deficit. Results show that oil pollution, waterlogging and water deficit significantly decreased the physiological functions of plants and can result in pre-visual changes in spectral and thermal responses. Various spectral …

Economic assessment of water management in agriculture: managing salinity and waterlogging in the Arkansas River basin and environmental water shortages in the Platte River basin
… and two essays addressing irrigation induced waterlogging and salinization in the Arkansas River Basin. Each essay integrates hydrologic modeling into the economic analysis to evaluate the effects of water management alternatives on agricultural production. In the first essay, Discrete …

Closing yield gaps in South Asian wheat production (Bihar, India and Terai of Nepal)
… management. In this research, we found that waterlogging stress early in wheat phenology reduced yield. This was attributed to farmers applying flood irrigation to the crop to the point of ponding at early wheat growth stages when the plants were more vulnerable. Waterlogging stress was …

The fluid mechanics of floating and sinking
… impact speed above which it sinks. We study the waterlogging of a floating porous body as a model for the waterlogging of the pumice ‘rafts’ that often form on bodies of open water after a volcanic eruption. We study the inflow of water that is driven by capillary suction and hydrostatic pressure …

Effects of Experimental Flooding Regimes on the Seasonal Carbon and Nitrogen Budgets of Silver Maple (Acer Saccharinum) and Speckled Alder (Alnus Incana Ssp. Rugosa)
… flooding regimes can expose wetlands to soil waterlogging during any part of the growing season. Carbon and nitrogen budgets of dominant riparian woody species may be seriously impacted when flooding occurs after the normal spring flood period. To better understand this process, I exposed …

Mortality of native forest vegetation in the Kaimai ranges
… leaf size, and other symptoms suggestive of waterlogging. Mortality appears to be episodic and several age classes can be distinguished by vegetation height. Recent mortality can be reliably dated to droughts in 1972 and 1946 but forest age class structure suggests a number of earlier dates …

A spatial decision support system for basin scale assessment of improved management of water quantity and quality in stream-aquifer systems
… illustrated their potential to reduce waterlogging and soil salinity, salt load to the river, and non-beneficial evapotranspiration in a strategic planning environment.

Experience and perceptions of climate change-related hazards, and the dynamics of technology-based adaptations in water use in Bangladesh: the case of Satkhira communities
… that cyclones, floods, salinity intrusion, and waterlogging were the primary climate-related hazards. Climatic factors coupled with anthropogenic activities resulted in disruptions to the freshwater supply, causing severe water scarcity for drinking and irrigation. Locals are adapting by …

Quantifying soil reinforcement by fibrous roots
… influence of abiotic stress from compaction and waterlogging. Barley with down-regulated lignin biosynthesis (Bowman 140) had increased nodalroot tensile strength of 37% compared to the parent line (Bowman Line) under good growth conditions, but this changed to -31% for compacted and 26% for …

Third landscapes for flood-resilience: Rethinking scales of green infrastructure in neighborhoods in Khulna, Bangladesh
… by the dual effects of rising sea levels and waterlogging during heavy rainfall. Additionally, an inadequate and not well-functioned drainage system, poor waste management, and lack of integrated planning for making the city flood-resilient have increased the impacts and suffering due to …

Dialing in the most corn-profitable and environmentally responsible nitrogen rate
… 2022, because early-season rainfall events and waterlogging coincided with high surface N accumulation from prior dry conditions. Nitrate leaching dominated in 2023 due to frequent early-season precipitation and drainage. This sequence shows that timing and intensity of precipitation, not only …

Characterisation of phytoalexin accumulation in maize inoculated with Cercospora zeina, the causal organism of grey leaf spot disease
… Meloidogyne incognita, Ostrinia nubilalis, waterlogging and drought stress. Finally promoter region analysis showed similar cis-acting regulatory elements in the 1kb region upstream of the promoter of both genes and defence specific elements. Thus kauralexin phytoalexins are produced in …

Dendrochronological investigations of living and relict yew trees from eastern England
… Oscillation, which jointly resulted in severe waterlogging of the region. The temporal coincidence of the shift with the highly-debated 4.2 ka climate event is recognised and critically discussed. While the 4.2 ka anomaly is commonly associated with extreme droughts in Asia that contributed to …

The growth, yield and water use responses of lentils (Lens culinaris Medic.) to irrigation
… were due to differences in their tolerance of waterlogging and their tendency to lodge. Water was extracted from deeper in the profile, and to a greater degree, by May sown plants than by September sown plants. This was probably due to more extensive root growth by May sown plants.
