ABSTRACT
Four spring wheat varieties exhibiting different degrees of dormancy were sampled during the latter stages of maturation and studied with a scanning electron microscope (SEM). Evidence of starch granule as well as protein matrix degradation was observed in the starchy endosperm adjacent to the embryo but not the aleurone. The extent of degradation differed among the four varieties. Excised wheat embryos from each variety were germinated and the alpha-amylase produced was analyzed by polyacrylamide gel isoelectric focusing.
