10 centrifugal treatments were conducted on maize rice and wheat to test centrifugal effect on Seed.Germination potential,germination percentage,root length,seedling length,seedling weight were measured at 7 days after germination.The results showed that different centrifugal treatments had remarkable promotion effect on germination potential and germination percentage.There was the biggest promotion on germination potential and germination percentage with 3000r/min for 10～15 minutes.The results also showed that 3000r /min for 15 minutes treatment was the best to root length,seedling length,seedling weight at 7 days after germination.
