PLATE 6 
A. —An ear of Reid f s Yellow Dent which is in the dough stage of development 
and is carried on a broken shank. The nodal tissues contained large accumulations 
of aluminum and iron salts, and the ear-node tissues were disintegrated. Organisms 
could not be found in the intemodal tissues, but local nodal infections at this stage 
of development of the plant had already occurred. 
B. —A close-up of the ear-node tissues. Note the disintegration of the tissues. 
These weakened tissues afford favorable places for growth of many kinds of organisms.
