Abstract

The sporulation was induced when fully grown cultures were given dip or spray treatment with distilled water (cold or hot) and thereafter, kept partially covered at different temperatures. Cultures dipped in cold water (4° C) for 4 minutes or sprayed with cold water (4° C) or hot water (58° C) and thereafter incubated at room temperature (13–26° C) in diffused sunlight, produced maximum number of spores within 60 hours. Incubating water treated cultures in diffused sunlight or complete darkness and age and scraping of the cultures had a considerable effect upon intensity of sporulation. The cultures yield a number of subsequent crops of spores when scraped and given dip treatment with cold or hot water, after obtaining each crop of spores.
