Abstract
The typical New Jersey corn stalk-rotting strain of G. zeae does not sporulate in laboratory surface culture. This organism produced, in a normal manner, abundant, typical macrospores only in shake culture on a medium consisting of simple-salts, yeast extract, and carboxymethylcellulose. Under these conditions aeration by shaking and carboxymethylcellulose was necessary for spore production. The nutritional condition of the inoculum influenced the extent of sporulation. Exclusion of KH2PO4 from the sporulation medium significantly reduced sporulation. Sporulation of G. zeae was poor in shake cultures of PD, V-8, Czapeks and Parks media.Keywords
