Effects of the concentration of urea on gelatinization of starch granules from the ae mutant EM10 and the wild-type cv Kinmaze and from lines with the ae and Ae genes on the waxy background. After incubation of starch granules in solutions of urea for 24 h, swelling was examined by measuring the volume of the swollen starch sediment. □, Kinmaze (wild type, AeAe/WxWx); ●, EM21 (wx mutant, AeAe/wxwx); ▵, EM10 (ae mutant, aeae/WxWx); ♦, AMF44 (double-recessive mutant, aeae/wxwx). Results are means ± sd of results from three replicate experiments.
