Responses of wheat (Triticum aestivum) to various concentrations of NaCl and levels of drought were followed. With the rise of NaCl and drought together, pectin and lignin was retarded in shoot or root systems. Considerable variations in the content of hemicellulose or cellulose were induced by NaCl-drought treatments. Salinity-drought induced a considerable increase in soluble sugars, starch, soluble proteins and proline in shoots or roots of the test plants. Biphasic action of salinity-drought treatments involving activation of free amino acids at shoot system and inhibition at root system. Considerable variations in the content of Na+, K+, Ca2+ or Mg2+ were induced by NaCl-drought treatments.
