Using the method of immunohistochemical localization the distribution of aquaporins, abscisic acid and IAA in the germinating seeds of the ABA-deficient mutant of barley (AZ34) and its original variety (Steptoe) was estimated. A high content of aquaporins in the roots of germinating embryos of Steptoe was found in comparison with AZ34. Revealed more intense staining of coleorhiza on ABA in germinating seeds embryo Steptoe. No documented differences in staining for IAA between Steptoe and AZ34. The effect of aquaporins, ABA and IAA on seed germination of barley was discussed.
