The induced osmotic stress inhibited growth and increased the percent dry matter and the level of free amino acids of the calli. Bigger changes were observed in drought sensitive «<Cappelle Desprez») and moderate resistant «<Chinese Spring») varieties than in drought resistant ones «<Saberbeg» and «Plainsman»). The putrescine content was highly increased in the drought sensitive variety. The cadaverine level was enhanced during osmotic stress in the drought sensitive and in one of the drought resistant varieties. The extractable protein content was decreased in drought sensitive and in moderate resistant varieties. During osmotic stress the aminopeptidase and carboxipeptidase activity increased significantly in the drought sensitive variety. Endopeptidase activity was low in all samples and no correlation was found between its activity and osmotic stress.

The profile of amino acid accumulation was different in the two parents. The amino acid concentration of the substitution lines belonging to the A, B and D genomes, respectively, altered characteristically under stress condition. The 'Cappelle Desprez' chromosomes associated with non-ionic osmotic stress-induced free amino acid accumulation were 5A and 5D.

The high-performance liquid chromatographic separation and determination of the extracted compounds showed that the microwave extraction method is more advantageous than other traditional extraction methods with regard to the yield of extraction and the time and cost of the procedure. The potential degradation of the extracted compounds may he considerably reduced .

By mixing sunflower, pumpkin, corn or rice germ presscake with cereals, the good protein quality of the former group might improve the biological value of the resulting coextrudates. The microstructure of such coextruded products was analysed with reference to their chemical compositions, nutritional characteristics and functional properties

The induced osmotic stress inhibited growth and increased the percent dry matter and the level of free amino acids of the calli. Bigger changes were observed in drought sensitive («Cappelle DespreZ») and moderate resistant («Chinese Spring») varieties than in drought resistant ones («Saberbeg» and «Plainsman»). The putrescine content was highly increased in the drought sensitive variety. The cadaverine level was enhanced during osmotic stress in the drought sensitive and in one of the drought resistant varieties. The extractable protein content was decreased in drought sensitive and in moderate resistant varieties.

The unique proteins of the albumin, gliadin and glutenin fractions of Hungarian winter wheat cultivars Bánkúti 1201 (early harvest time), Martonvásári 23 (medium harvest time), and Martonvásári 15 (semi-late harvest time) were analysed. An acidic phosphate buffer containing a polymeric additive and organic modifiers was used in capillary zone electrophoresis mode. Formation of albumin followed the same time scale, and the patterns were quite similar, for all three cultivars. For gliadins and glutenins the time scale and patterns were different and some correlation was observed between harvest time and gliadin formation.

The different protein components of the albumin, globulin, gliadin and glutenin fractions from the Osborne extraction procedure were analysed. The wheat sample was a Hungarian winter wheat, cultivar Martonvásári 23. The protein fractions were analysed by capillary zone electrophoresis using a low pH phosphate buffer containing a polymeric additive and organic modifiers. The albumins and gliadins as well as glutenins showed a characteristic pattern of development during the maturation process. For these fractions the development occurred at different stages of maturation. The formation of protein fractions of wheat at different stages of maturation—and thus the entire maturation process—could be well characterised by high-performance capillary electrophoresis.
