Abstract
Interspecific compatibility and incompatibility have been examined through the genus Populus. General methods of manipulation have been developed to break the incompatibility barriers. These methods are described and a hypothesis is put forward to account for the results. This proposes that at least two factors are involved, one attached to the pollen (P) and one to the stigma (S), and that the interaction of these (PS) is critically involved in the total process. Implications for future plant breeding are discussed. Interspezifische Verträglichkeit und Unverträglichkeit sind im Genus Populus untersucht worden. Wo Unverträglichkeit vorliegt, wurden Methoden entwickelt, um sie zu überwinden. Diese Methoden werden beschrieben. Die Ergebnisse führen zu einer Hypothese, in der angenommen wird, daß mindestens 2 Faktoren eine Rolle spielen. Einer ist mit dem Pollenkorn (P) verbunden, der andere mit dem Stigma (S). Ihr Zusammenspiel im Verträglichkeitsprozess ist von entscheidender Bedeutung. Schlußfolgerungen für zukünftige Züchtungsarbeiten werden erörtert.Keywords
