Remote sensing of water stress in fynbos vegetation
… and accurate method for determining drought stress in Fynbos vegetation. I hypothesize that (1) water stress in fynbos is detectable with the use of a remote sensing index, namely NDVI and (2) that the remotely sensed trends will correlate with ground truth measures of water stress.

Crop-water stress index models for cool season turfgrasses
Crop Water Stress Index (CWSI) technology has shown potential in improving irrigation timing as it determines timing based on the plant's need. Research was conducted to better apply this technology to turf management. The objectives of this study were (i) to determine the complexity of model …

Physiological responses of common bean(Phaseolus vulgaris L.)genotypes to water stress
… (Phaseolus vulgaris L.) is highly constrained by water deficit especially occurring during the reproductive development which significantly reduces the grain yield. A late planted crop, is likely to experience water stress. The purpose of the study was to determine the association of the …

Impact assessment of hydroclimatic change on water stress in the Indus Basin
… availability. Climate change, growth in sectoral water demands, and changes in water management infrastructure could have a profound impact on water stress in the coming decades. The interplay and contribution of these influences is explored using a model of the managed Indus River basin. To …

Crop water stress under climate change uncertainty : global policy and regional risk
… the potential impacts of climate change on crop water stress and the risk implications for policy makers due to underlying uncertainty in climate models. This thesis presents the Community Land Model - Agriculture module (CLM-AG) that models crop growth and water stress. It is a global generic …

Ethylene production by loblolly pine seedlings during cold storage and water stress
… seedlings during cold storage, and the effect of water stress on ethylene and aminocyclopropane-1-carboxylic acid (ACC) production in two half-sib loblolly families were investigated. Seedlings stored in Kraft-Polvethvlene (K-P) bags showed a general trend of increasing ethylene concentrations …

Genotypic differences and water stress-induced changes in lipids of maize hybrids
… for their ability to tolerate mild osmotic stresses (-0.4 and -0.6 MPa, polyethylene glycol-induced), osmotically induced changes in lipid composition, and differences in membrane stability as measured by electrolyte leakage. Inherent differences among the hybrids included reduced dry matter …

Remote Sensing of 21st Century Water Stress for Hazard Monitoring in California
… 2012-2015, and 2020-2022. A portion of the water lost during these two decades is due to intense groundwater overdraft of the Central Valley Aquifer. This groundwater overdraft has led to poroelastic compaction of the aquifer system and subsidence of the land surface. Water mass loss also …

Evaluating Future Runoff, Water Stress and Fluvial Flooding in China under Climate Change
… faces complex changes in runoff variability, water stress, and fluvial flood hazards under climate change and socioeconomic development. Understanding how these processes may evolve under future scenarios is critical for long-term water resource planning and climate adaptation. However, …

Biostabilization of Lipid Bilayers: Dealing with Water Stress in Embryos of Artemia franciscana
… stabilization of lipid bilayers during water stress by protectants found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially solubilize the outer …

Barley growth, physiology, and forage quality as influenced by defoliation and water stress
<p>Information on how limited water supply might affect the physiological changes that take place after defoliation of barley (Hordeum vulgare L.) after defoliation and their effects on forage-quality characteristics is needed. The objectives of this study were to investigate defoliation and water …

Climate change, water stress and agriculture in the Indus Civilisation, 3000-1500 BC
… Monsoon ca 2100 cal BC led to increasing crop water stress, and hence potentially contributed to the Civilisation’s decline by reducing food supply. This hypothesis is frequently invoked in discussions of the Civilisation’s end, yet until now, has not been empirically tested. Using material …

Effects of water stress and application timing on glyphosate activity in forest trees
… were conducted to investigate the role of water stress and time of glyphosate spraying in the variation in glyphosate efficacy. Data on water potential, foliar sugar and starch content, weather, and growth response were gathered for loblolly pine and four of its major competitors on 16 …

'Hass' avocado tree water use and the effects of water stress on fruit development
‘Hass’ avocado tree water use and the effects of water deficits on fruit development were assessed in New Zealand from 2017 to 2019. Avocado tree water use was quantified by sap flow measurement and the soil water balance method at three sites in the main avocado growing regions of the Bay of …

Characterization of a Novel Water Stress Related Protein from Geranium (<em>Pelargonium hortorum</em>).
… 4-CL is downregulated during water stress by ABA. This is significant in that it has not previously been reported. Northern analysis and PCR product sequence analysis further confirmed this expression data.</p>
