Abstract: 
In spring barley (cv. Gerda) the influence of different protein contents of the grain on root and shoot growth, and on the yield of the subsequent generation was studied. The trials were carried out in pot and field experiments with 3 N levels and 2 or 3 grain sizes. The physiological processes of germination, the growth pattern, and the yield performance of spring barley grains with different protein contents were followed. The protein contents of protein-rich grains were equally high in the embryo, aleurone layer and endosperm. The differences in the amino acid composition between high protein and low protein grains were small in the embryos, larger in the aleurone layer (especially in glutamic acid and proline), and particularly conspicuous in the endosperm (mainly glutamic acid and proline). The amylase activity in spring barley grains rich in protein was high leading to a quick degradation of starch in the germinating grain. These processes led to improved growth of seedlings and juvenile plants and higher grain yield. Spring barley plants from protein-rich grains can better withstand unfavorable ecological conditions (low temperatures, low availability of nutrients). Increased N fertilization in the following generation reduced the differences in yield between high-protein and low-protein barley.
