ABSTRACT
An association between grain dormancy and peroxidase activity was found within a cultivar and among cultivars with different levels of dormancy. Columbus, a hard red spring wheat with harvest-time sprouting resistance resembled its dormant parent, RL 4137 in peroxidase activity more than its recurrent parent, Neepawa. Both anionic and cationic peroxidases were examined by electrophoresis and activity of one anionic and one cationic isoenzyme was different in dormant and non-dormant grains.
