Abstract
Laubmoos. Polare Keimung der Sporen, Übersicht über die Gesamtentwicklung des Protonemas, Übergang eines Chloronemas zum Kaulonema, Zellteilung der Spitzenzelle, Bildung von Seitenfäden an Kaulonemazellen, Gesamtübersicht bis zur Anlage von Knospen in einem Hexenring. Mit Zeitraffung.
The film shows the various stages of the protonema development of a moss. It begins with the germination of the Funaria hygrometrica spores. Then follows a review of the complete development of the protonema on an agar surface. Single shots then show the change of a chloronema filament into the caulonema stage with sloping cross-walls, cell division, and the formation of side filaments on caulonema cells from various angles in bright field and in phase contrast microscope. The film includes with another summary of the protonema development within a four week period - with fast motion effect - beginning with spore germination and ending with a ring of buds.
