Experimental work in the field and laboratory has indicated that corn having a relatively corneous endopserm produces seedlings superior in vigor to those produced by grain soft or floury in composition. Both physical and chemical explanktions have been given for this phenomenon. Dungan (5)~ has reported that the starch reserves of horny corn disappear more rapidly during germination than those of floury corn. It is the purpose of this paper to present additional evidence of the relationship that exists between kernel composition and seedling vigor and to show that this relationship may be partially explained on the basis of the activity of hydrolytic enzyms in the germinating grain.
