| Abstract: | Experiments were conducted to study the effect of bioprotectant on germination of maize seeds and their physiological properties. The results showed that three kinds of bioprotectant in appropriate concentra-tion could improve germinating energy, germinating percentage, germination index and vigor index of maize seeds. The root activity and the activities of SOD and POD were higher than those of control. |
