Water retaining agent (WRA) is widely used for soil erosion control and agricultural water saving. Here, we evaluated the effects of the combination of beneficial soil bacterium Bacillus amyloliquefaciens strain GB03 and WRA (the compound is super absorbent hydrogels) on drought tolerance of perennial ryegrass (Lolium perenne L.). Seedlings were subjected to natural drought for maximum 20 days ...

Frequent monitoring of stress levels in turfgrass is key to maintaining healthy turfgrass stands. Current methods used to monitor turfgrass for drought and salinity stress can be time consuming and expensive. This study was conducted to determine if data obtained from digital image analysis and spectroradiometry could accurately detect drought and salinity stress in hybrid bluegrass. Furthermor...

Dehydration affects the photosynthetic apparatus. The impact of dehydration on photosynthesis was assessed in twelve Mediterranean species representing different growth forms. Rapid and slow experiments were conducted to (1) compare water stress among forms, (2) rank according their drought tolerance. reduced electron transport up PSI, reduction being linearly related leaf relative content (RWC...

One of the most significant abiotic factors that has a negative impact on wheat productivity globally is drought. To comprehend impacts drought and propose remedies, numerous studies are carried out various varieties. In this study, 50 µM methyl jasmonate (MeJA) was applied to tolerant Gün 91 sensitive Bezostaja cultivars they were exposed stress for 15 days. The responses MeJA application deve...

Water distribution systems (WDSs) are becoming equipped with advanced feedback loops, which require specialized methods and software tools to model such systems. The aim of this work is demonstrate the usefulness rigid water column (RWC) analyze dynamic interactions between these loops system stability. Our fills gap extended period simulation, used for steady state analysis, transient surge an...

drought stress is a major factor limiting crop production. investigation of physiological characteristics related to drought tolerance and crop production may be useful in selecting drought tolerant cultivars as well as in improving crop yield. two drought tolerant (azar2 & back cross roshan) and two drought susceptible (marvdast & shiraz) cultivars were investigated in both greenhouse and fiel...

The orphan crop, Eragrostis tef, was subjected to controlled drought conditions to observe the physiological parameters and proteins changing in response to dehydration stress. Physiological measurements involving electrolyte leakage, chlorophyll fluorescence and ultra-structural analysis showed tef plants tolerated water loss to 50% relative water content (RWC) before adverse effects in leaf t...

We investigated the photosynthetic limitations occurring during dehydration and rehydration of Xerophyta humilis, a poikilochlorophyllous resurrection plant, and whether volatile and non-volatile isoprenoids might be involved in desiccation tolerance. Photosynthesis declined rapidly after dehydration below 85% relative water content (RWC). Raising intercellular CO(2) concentrations during desi...

For the first time novel high-energy conformers-A·T(wWC) (5.36), A·T(wrWC) (5.97), A·T(wH) (5.78), and A·T(wrH) (ΔG = 5.82 kcal·mol-1) (See Graphical Abstract) were revealed for each of the four biologically important A·T DNA base pairs - Watson-Crick A·T(WC), reverse Watson-Crick A·T(rWC), Hoogsteen A·T(H) and reverse Hoogsteen A·T(rH) at the MP2/aug-cc-pVDZ//B3LYP/6-311++G(d,p) level of quant...
