Variabilität von Scenedesmus acuminatus (Lagerh.) Chod. und Scenedesmus pectinatusMeyen in Nährlösungen mit unterschiedlichem NaCI-Gehalt

Abstract

Clonal cultures from Scenedesmus acuminatus (Lagerh.) Chod. and Scenedesmus pectinatusMeyen were studied in regard to the variability of coenobia by an intensive cultivation using nutritional medium with different NaCl concentrations. With an increasing salinity of the medium in the clonal cultures from both species, coenobia corresponding to Scenedesmus regularis SVIR. were found. Concrete conclusions for changeability of characteristics concerning the taxonomic status of S. acuminatus (Lagerh.) Chod. and S. pectinatusMeven are drawn.
