TABLE 2.

Variables that did not affect the inoculum size effect in C ulmi at 20 h of growth

Variable	Range
Temp (°C)	15-29a
pH	3-7
Glucose concn (%)	0.4-8
Sucrose concn (%)	0.4-8b
Proline concn (mM)	0-100
Phosphate concn (mM)	5-500
Spore age (days)	0-10
Atmospheric CO2 (%)	0-15%

^aNote that 32°C is the maximum temperature at which these strains of C. ulmi will grow (11).

^bFor C. ulmi, glucose and sucrose are interchangeable in terms of all growth parameters (11, 14).
