An Optimum Environment for the Culturing of Coryneum carpophilum. R. E. Williams, Graduate Fellow, Department of Plant Sciences, University of Idaho, Moscow 83843, Present address of senior author: Intermountain Forest and Range Experiment Station, Box 469, Moscow, Idaho, 83843; A. W. Helton, Plant Pathologist, Department of Plant Sciences, University of Idaho, Moscow 83843. Phytopathology 61:829-830. Accepted for publication 16 February 1971. DOI: 10.1094/Phyto-61-829.
Three isolates of Coryneum carpophilum were subjected to variations of temperature, nutrition, and hydrogen ion concentration to identify optimum conditions for linear growth on an agar medium. Results showed that a temperature: carbon: nitrogen: pH interaction was present, with the best single set of conditions for most rapid growth of the fungus being use of a basal medium in which beta-maltose served as the carbon source, l-asparagine provided the nitrogen, an initial pH of 5.4-5.8 was utilized, and the medium was incubated at 15 C.
