Influence of certain environmental factors on spore germination and spore differentiation in Pithophora oedogonia

Abstract

Of the light- and dark-stored spores of Pithophora oedogonia for over a period of one and half years, the latter exhibited complete failure of germination under controlled culture conditions. pH 8, blue light and 1 klx intensity of white light proved to be ideal conditions as they resulted in optimum germination of akinetes. pH 5, green light and 0.25 klx light intensity delayed the initiation of sporulation and also reduced percentage sporulation. All filaments died before sporulation in pH 4. © 1987 Institute of Microbiology, Academy of Sciences of the Czech Republic.
