Abstract: Taking Gomphrena alba and Gaillardia aristata as material, we studied the depilation technique of flower seeds with villus and the repair function of PEG-6000 to injury of depilation flower seeds. The result showed: Every flower variety had an optimum H2SO4 concentration. The best concentration to Gomprena alba and Gaillardia aristata is 70%、60% respectively. At the same time, 20% PEG-6000 had a best repairing effect. After soaked in 20% PEG-6000 for 8 hours, the germination percentage、germinating capacity and the activity of SOD and CAT of the depilation flower seeds in creased obviously, while the content of MDA and electric conductivity decreased apparently.
