Abstract: To study the effects of maize seed dressing with chlorantraniliprole on seed germination, seedling growth and physiological and biochemical indexes, plate experiments in incubator and indoor pot experiments were conducted to study the seed germination, seedling growth (plant height, root length, root shoot ratio, etc.), physiological and biochemical indexes (protective enzyme, root activity and chlorophyll content, etc.) of maize by seed dressing with different dosage (0.5, 1, 2, 3, 4 g/kg) of hlorantraniliprole. The results showed that chlorantraniliprole at 0.5- 3 g/kg significantly increased the germination potential, germination rate, germination index, vigor index of maize and increment in seedling stage, induced the activity of CAT, POD, SOD, PAL and PPO in maize seedling leaves, and increased root activity, chlorophyll content, sugar content and soluble protein content. Chlorantraniliprole inhibited the growth of maize after treated with 4 mg/kg, but the indicators were still higher than that of the control. In conclusion, chlorantraniliprole at suitable dosage could significantly promote seed germination and seedling growth of maize.
