Salinity Screening - 80mM solution. CONDITIONS: Green House - 18-25C METHOD NARR: Salt treatments consisted of water solutions containing 0, 40, 80, and 120mM NaCl and 20 and 40 mM Na2SO4. The treatments were increased in gradual increments of 20mM per day to prevent severe stress. RESULTS NARR: Sodium sulfate reduced plant survival more than sodium chloride on an equal molar basis. AUTHOR EXPLANATION: SO4 ions were more toxic than Cl ions. Survival of an accession treated with one salt was a good indicator of survival with the second. There was no relationship between accessions of known heat or drought resistance and salt resistance.
