Abstract:
Taking Salvia splendens seeds as test materials,treated with different concentrations of GA or ABA,the effects of plant hormones，GA and ABA on the germination and dormancy of the seeds were studied.The results showed that GA or ABA treatments had obvious effects on germination of Salvia splendens seeds.Both,the germination of the seeds and the vigor of the seedlings were markedly improved by GA treatments.The appropriate concentration (80 mg/L) of GA treatments promoted the germination of Salvia splendens seeds，accelerate speed and vigor of the seeds germination.ABA treatment (0.1 mg/L) restricted the germination，promoted the dormancy of the seeds.
