TOCIIINAI : STUDIES OX THE rilvsior.OGV OF Fusarium Uni. 37 



Redistilled Water (ILO) lOOO.OO cc. 



Took 50 cc. of the solution in an I'.rlcnmj'er's flask of the capacity of 

 200 cc. Sterilized, and inoculated with a bit of the myceliuni and conidia. 

 Incubated them at the various temperatures. After ten days, strained the 

 mycelium through pieces of filter paper of known weights, in order to com[)are 

 the'growth of the fungus for e\er}' temperature in the dry weight. Cultures 

 for each temperature were in triplicate. 



The obtained results are following. 



1. At 3° to 5° C. (in a cold chamber.) 



No growth. 



But the fungus maintained its vitality, and by incubating them at 

 25°C., the fungus grew vigorously. 



2. At 10° to I2°C. (in an incubator.) 



a trace. 



3. At 13° to I5^C. (in an incubator.) 



A little. 



Dry weight of mycelium. . . .0.007 §• 



4. At 20''C. (in an incubator.) 



Moderate. 



5. At 25"C. (in an incubator.) 



Good. Aerial mycelium grew vigorously, covering all over the surface 

 of the meilium. 



Dr>' weight of the mycelium. . . .0.462 g. 



6. At 28"C. (in an incubator.) 



Very good. Aerial mycelium grew vigorously, covering all over 

 the surface of the medium. 



Dry weight of the mycelium. .. .0.550 g. 



7. At 30'C. (in an incubator.) 



Very good. Aerial mycelium grew most vigorously, covering thick 

 all over the surface of the medium. 



Dry weight of the mycelium. . . .0.610 g. 



8. At 34° to 35-C. (in an incubator.) 



Fair. Aerial mycelium grew poorly, scarcely covering over the
