PLATE 4 
Representative com seedlings, from inoculated and uninoculated seed, grown at 
different soil temperatures. 1 
A. —Plants grown at a soil temperature of 12 0 C. Plants from the inoculated seed 
were all killed before emerging. 
B. —Plants grown at a soil temperature of 16 0 C. Plants from the inoculated seed 
were badly diseased. About half of them blighted soon after emerging. 
C. —Plants grown at a soil temperature of 20° C. Plants from the inoculated seed 
almost as badly diseased as those grown at 16 0 C., represented in B. 
D. —Plants grown at a soil temperature of 24 0 C. Plants from the inoculated seed 
were healthy except for a few minor root lesions. 
* In each set of plants from A to D, (1) represents typical plants from seed inoculated with conidia of 
GtbbereUa saubinetii and (9) represents seedlings of the same age and from the same seed uninoculated.
