Abstract
Different barley cultivars were exposed to a salt-stress of 100 mM NaCl, in hydroponic conditions, one week after germination using diluted Hoagland solution for nutrition. Furthermore the effect of the presence or absence of calcium was analyzed, using a calcium-less or a calcium-containing solution. Ion uptake was followed for 48 hours, growth as an increase of dry matter was measured as was the ionic content for potassium and sodium. In parallel with this uptake experiments we followed the sodium fluxes, using 22Na, to determine ratios of accumulation of xylem transport. All cultivars were also separately exposed to the stress for half an hour, after which the phloem transport of sugars was measured. Having data on several physiological parameters we have been able to classify the different cultivars from relative resistent to sensitive to salt-stress.
