Abstract

Leafproteins of Triticum dicoccum cv. Khapli determined by the agar-gel-diffusion analysis and by electrophoresis were partly decomposed with simultaneous loss of resistance to Puccinia graminis f. sp. tritici race 11 in detached leafcultures. However, abscisic acid treatment, which induced protein decomposition (senescence) of attached leaves similar to that induced by detachment, did nőt affect rust resistance. Furthermore, treatment with maleic hydrazide did nőt influence protein composition ofprimary leaves, bút rust resistance was still lost in Khapli seedlings. It is concluded that, with the methods used in this study, protein changes in Khapli wheat leaves do nőt correlate with changes in resistance to stem rust.
