The alpha-amylase, exoprotease, and endoprotease activities of four secondary hexaploid triticales and one hard red spring wheat were followed from 21 days post-anthesis to full maturity during the 1983 and 1984 growing seasons. Alpha-Amylase activity of the triticales generally increased during kernel development, while exo- and endoprotease activities generally decreased. At full maturity, all triticales were higher in whole grain alpha-amylase and protease activities than Marquis wheat checks grown in the same year. Of the three enzyme systems examined, differences in alpha-amylase activity due to cultivar and year were most apparent.
