PLATE io 
Results of the culture method of determining internal fungi in seed com. Fifteen 
kernels in each sample were surface-disinfected and washed in sterile water; io of 
these kernels were placed in one dish on 20 cc. of nutrient dextrose agar. Five kernel s 
were placed each in a separate sterile dish, and the points of each of these were cut off, 
crushed, and plated. The fungi which were internal readily developed. The 
culture work on sample 10 B is here shown, in which 70 per cent of the kernels were 
infected with Viplodia zeae (See cultures in dishes marked B, C, D, and E); 20 per cent 
of the kernels were infected with Gibberella saubinetii (See dish marked F.); 80 per 
cent of the kernels were infected with Cephalosporium sacchari (See dishes marked 
A, D, and E). In this sample Diplodia zeae was the fungus most active in inhibiting 
germiniation. G, coremial growth produced by Cephalosporium sacchari. The 
coremial growths are not usually so pronounced as this. 
Somewhat reduced.
