Efficient management of irrigation water is fundamental in agriculture to reduce the environmental impacts and to increase the sustainability of crop production. The availability of adequate tools and methodologies to easily identify the crop water status in operating conditions is therefore crucial. This work aimed to assess the reliability of indices derived from imaging techniques—thermal in...

two glasshouse and field experiments were conducted to assess the effects of root system, water uptake, water use efficiency and early vigor on yield and drought tolerance of bread wheat in two successive farming seasons (2009-11). the experiments were conducted as randomized complete block design and two-year results analyzed as combined design. considerable genetic variation was observed amon...

BACKGROUND Long-stemmed and semi-dwarf cultivars of triticale were exposed to water stress at tillering, heading and anthesis stage. Quantitative determination of free and cell wall-bound polyamines, i.e. agmatine, cadaverine, putrescine, spermidine and spermine, was supplemented with an analysis of quantitative relationships between free and cell wall-bound polyamines. RESULTS The content of...

The adverse effects of salinity and PEG-induced water stress on growth of Matricaria chamomilla were assessed at the germination stage using osmotic solution of NaCl (0, -0.175, 0.358, -0.541, -0.716 MPa), and polyethylene glycol (PEG 6000) (0, -0.05, -0.1, -0.2, -0.3 MPa), respectively. Effect of NaCl salinity stress (0, 40, 80, 120 and 190 mM NaCl) at early growth stage of chamomile was also ...

Dietary supplements are widely used to manage stress and related consequences. However, the exact pathological mechanism and cellular cascades involved in the action of these supplements are not properly understood so far. Therefore, the present study has been designed to explore the neuroprotective mechanism of rutin against immobilization stress-induced anxiety-like behavioural and oxidative ...

Evapotranspiration (ET) over an oilseed crop, Camelina sativa, was evaluated for an experimental plot in Maricopa, Arizona between December 2006 and April 2007. Camelina (cv. Robinson) was grown in a 1.3-ha field in a randomized design containing 32 plots replicated for four levels ofwater depletion: 40, 55, 65, and 75%. Six supplemental plots evaluatedwater stress with 85% soil water depletion...

Changes in water-soluble carbohydrates were examined in the leaves of the resurrection plant Xerophyta viscosa under conditions of water deficit. Sucrose and raffinose family oligosaccharides (RFOs), particularly raffinose, increased under these conditions, with the highest concentrations evident at 5% relative water content [RWC; 23.5 mg g(-1) dry weight (DW) and 17.7 mg g(-1) DW, respectively...

Two experiments were conducted to study the effects of water deficit stress on the germination, emergence and seedling growth of sorghum [Sorghum bicolor (L.) Moench] using Completely Randomised Block Design in four replications. Five sorghum cultivars (Jigurti, Gambella 1107, Meko, 76 T1 #23 and P9403) were evaluated under three water deficit stress treatments (0, -0.20 and -0.85 MPa) using PE...

The paper demonstrates the application of a new water accounting plus (WA+) framework to produce information on depletion of water resources, storage change, and land and water productivity in the Indus basin. It shows how satellite-derived estimates of land use, rainfall, evaporation (E), transpiration (T ), interception (I ) and biomass production can be used in addition to measured basin out...
