Abstract

Growth of six isolates of Fusarium solani on potato dextrose agar was determined with (1) continually changing temperature programs, (2) programs consisting of two alternating constant temperatures, and (3) a constant temperature program. All programs had a mean of 70º F. Growth increased with an increase in temperature fluctuation of 10 or 20ºF., but decreased with a fluctuation of 40º F. Significant differences were found in the growth rates of the isolates.
