Abstract

Suitability of sweet potato as a culture medium ingredient for Sclerotium rolfsii Sacc. was studied. S. rolfsii grew in the culture media where sweet potato was used as a substitute for white potato in the preparation of potato-dextrose agar (PDA). The fungus on PDA produced profuse, aerial, and straight mycelia and abundant sclerotia. In cultures with varied proportions of sweet potato as ingredient, mycelial growth was characterized as creeping, branched and scanty to profuse; very few sclerotia were formed. Sweet potato leaves or stems as natural substrate for S. rolfsii supported profuse and aerial mycelial growth; abundant sclerotia were also formed.
