Two barley cultivars were subjected to water stress by immersing their root system in PEG 6000. The relative water content (RWC) of the leaves fell under these conditions and membrane disorganisation was evidenced by the injury index data. The two genotypes differed in their leaf water content under the applied stress. The aim of this work was to examine the relationship between proline accumul...

the effects of arbuscular mycorrhizae on water use efficiency and some growth characteristics of maize were studied at three water regimes. an farm experiment was carried out using a split plot based randomized complete block design with 3 replications. main plot was under water deficit condition (100%fc, 66%fc, 33%fc) and sub plot included application of two species of mycorrhizae, m1:glomus m...

We have characterized the growth responses of Arabidopsis thaliana seedlings to water deficit. To manipulate the water potential, we developed a method whereby the nutrient-agar medium could be supplemented with polyethylene glycol (PEG 8000); PEG was introduced into gelled media by diffusion, which produced media with water potential as low as -1.6 MPa. For dark-grown plants, hypocotyl growth ...

monthly discharge is one of the most important factors considered in designs and hydrological works. some watersheds are not equipped with needed hydrometric equipment. in such a case average monthly discharge could be estimated from regional monthly water balance models of representative watersheds. in this study, thornthwaite & mather (tm) model were used in the pishkouh watershed in arid...

PURPOSE Previous studies have shown that heart rate complexity may be a useful indicator of patient status in the critical care environment but will require continuous, accurate, and automated R-wave detection (RWD) in the electrocardiogram (ECG). Although numerous RWD algorithms exist, accurate detection remains a challenge. The purpose of this study was to develop and validate a novel fusion ...

Abstract Seed germination is an important phase of plant development during which soil water availability is crucial. Salinity can affect seed germination in two ways: 1) Change of osmotic potential of available water, 2) toxicity effects. In this experiment, interactive effects of salinity and water deficit on germination criteria of two species of A, littoralis and A. logopoides were...

in order to compare photosynthetic features of triticale, bread wheat, and barley under water deficit conditions, this experiment was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, and a new variety of barley were compared under well watered (ψsoil= -3 bars) and soil water deficit (ψsoil= -12 bars) conditions in a randomized compl...

We examined the extent of osmotic adjustment and the changes in relative water content (RWC) and transpiration rate (i.e., relative stomatal function) that occur in water-deficit-conditioned 6-year-old Thuja occidentalis L. (eastern white cedar) trees in response to a severe drought. Trees conditioned by successive cycles of mild or moderate nonlethal water stress (conditioning) and nonconditio...

ABSTRACT- To investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including L1 (Field Capacity, FC), L2 (70% Available Water Content, AWC), L3 (50% AWC), and L4 (30% AWC), within three growth stages- including stem elongation (T1), onset of flowering (T2) and silique fo...
