salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. a greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (bamiand hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mm nacl) at the college of agriculture,shiraz university, shiraz, iran in 2008. plant dry weig...

Spherical-like hydroxyapatite (HA, Ca10(PO4)6(OH)2) particles were prepared by the co-precipitation method in a simulated physiological environment. The effect of calcining temperature, calcining time and the Ca/P ratio of the initial feeding on the morphology and crystallinity of HA were investigated in detail. Interestingly, wh...

Salinity is a major limitation ecological factor for plant development in arid and semi-arid regions. The ionic imbalance, deficiency of nutrients and degradation of plant metabolites are caused by saline conditions, are affected by the reduction ratio of potassium (K) then sodium (Na). In this research foliar applications of humic acid (HA) for improve the absorption of K under salt stress was...

introduction: almond (prunus amygdalus b.) is one of the most important crops consumed as a dry fruit and it is mainly adaptable to arid and semi-arid regions mostly suffering from salinity stress (8). soils with dry humidity regime are dominant in iran and in the world at large and mostly include regions with more evaporation than precipitation. this in turn leads to increased salinity of the ...

screening methods that are effective in the early stage of growth will potentially provide the largest quantity of breeding material. although various screening methods under greenhouse have been proposed, potential effective approaches must be described a good correlation with results under field conditions. this study was aimed to assess the correlations between traits obtained from four salt...

BACKGROUND/AIM Calculation of the chloride:sodium (Cl-:Na+) ratio is proposed to enable a quick evaluation of the effect of Cl- and Na+ on the acid-base balance in critically ill patients. In the present study, the relationship of the Cl-:Na+ ratio of septic patients with acid-base status and ICU mortality were investigated. MATERIALS AND METHODS In our two-center study, 434 patients who were...
