The amylose content of waxy and non-waxy grain samples. Based on the results of the iodine test, six sets of samples were chosen. The members of each group had similar results in the iodine test. The dark green, green and pale-green bars represent the non-waxy grains, and dark red, red and pale red bars represent the waxy grains. Each bar represents the mean amylose content as calculated from three replicate measurements. The error bars represent standard deviation.
