The egg apparatus in the ovule of maize consists of three cells, and in the center of the embryo-sac is an endosperm nucleus. The fertilization of the egg cell results in the formation of the corn em- bryo, while the double fertilization of the endo- sperm nucleus by the second sperm nucleus pro- duces an immediate effect on the color of the reserve food stored about the embryo. This imme- diate effect of the pollen on the offspring kernels is called Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bailey, L.
