Abstract
In the light microscope the nuclei of the leaf cells of Selaginella martensii show ring-shaped inclusions. These rings are Feulgen positive and most probably contain DNA. An electron microscopic examination of these ring-shaped inclusions shows that they are composed of closely packed tubular elements which have a constant diameter and unknown length. These bundles are often surrounded by a number of larger tubular elements which may be built up of tubular subunits. Die Kerne der Blattzellen von Selaginella martensii zeigen im Lichtmikroskop ringförmige Einschlüsse. Diese Ringe sind Feulgen-positiv, enthalten also wahrscheinlich DNS. Sie bestehen aus einem dichtgepackten Bündel tubulärer Elemente konstanten Durchmessers, jedoch nicht genau bestimmbarer Länge. Die Ringe sind häufig von einer wechselnden Zahl größerer tubulärer Stränge umgeben, die aus röhrchenförmigen Untereinheiten bestehen können.Keywords
