The relative magnitude of adjustment in osmotic potential (psi(s)) of water-stressed cotton (Gossypium hirsutum L.) leaves and roots was studied using plants raised in pots of sand and grown in a growth chamber. One and three water-stress preconditioning cycles were imposed by withholding water, and the subsequent adjustment in solute potential upon relief of the stress and complete rehydration...

Water shortage in the arid-semiarid regions of China seriously hampers ecosystem construction. Therefore, elucidation of the mechanisms by which vegetation in that area responds to drought stress may enable us to improve utilization of limited water resources and thus contend with the problem of drought and water shortage. We studied Bothriochloa ischaemum, a native grass species, conducted pot...

  Abstract In order to evaluate morpho-physiological traits of confectionery sunflower under different irrigation regimes, an experiment was carried out under field conditions in Agricultural Research Center of West-Azerbaijan province, Urmia, Iran in 2012. Fifty six confectionery sunflower landraces were arranged in 7 × 8 rectangular lattice design with two replications in each one of well-wat...

Total body water (TBW) and total body potassium (TBK) were studied in 40 ileostomists before (with conventional ileostomy) and one year after conversion to a continent ileostomy. Each patient acted as his own control. Total body water was determined by using an isotope dilution technique and TBK by counting the gamma radiation from the naturally present nuclide 40K in a whole body counter. Meas...

34 Elucidating the genetic control of rooting behaviour under water-deficit stress is essential to 35 breed climate-robust rice cultivars. Using a diverse panel of 274 indica genotypes grown 36 under control and water-deficit conditions during vegetative growth, we phenotyped 35 traits, 37 mostly related to root morphology and anatomy, involving ~45,000 root scanning images and 38 nearly ~25,00...

Visceral hypersensitivity has been implicated as an important pathophysiological mechanism in functional gastrointestinal disorders. In this study, we investigated whether the sustained visceral hyperalgesia induced by repeated psychological stress in rats involves the activation of CRF(1) signaling system using two different antagonists. Male Wistar rats were exposed to 10 consecutive days of ...

Stressful experiences external to a marriage (e.g., work stress, finances) are often associated with poor relationship functioning and lowered marital satisfaction, a phenomenon called stress spillover. To date, however, little attention has been devoted to understanding the specific mechanisms through which stress may lead to maladaptive relationship patterns. Drawing from theories of self-reg...

terminal drought stress during grain filling period has recently become more common in the semiarid mediterranean regions, where wheat (triticum aestivum) is grown as an important winter cereal crop. the objective of this experiment was to study the effect of terminal drought stress on grain yield, gas exchange variables, and some physiological traits of nine bread wheat cultivars. an experimen...
