Mit rund 25.000 Arten bilden die Orchideen eine der größten und am weitesten verbreiteten Pflanzenfamilien auf der Erde. Charakteristisch sind ihre winzigen und extrem leichten Samen. Das Trockengewicht eines einzelnen Samens liegt dabei zwischen 0,3 und 24 Mikrogramm, so dass 100.000 Samen nicht viel mehr als 1 Gramm wiegen. Einer Forschungsgruppe im Labor für Isotopen-Biogeochemie der Universität Bayreuth unter der Leitung von Prof. Dr. Gerhard Gebauer ist es jetzt erstmals gelungen, die Verteilung von Kohlenstoff- und Stickstoff-Isotopen in einzelnen Orchideenkeimlingen mit hoher Genauigkeit zu bestimmen. Isotope sind Atome, die sich allein durch die Anzahl der Neutronen im Atomkern unterscheiden.
