Abstract: Seeds of MS yunyan 87, MS K326 and honghuadajinyuan were used to study effects of gibberellin (GA₃) priming with various pH values on the seed germination and seedling quality. The results showed that the priming treatment of MS yunyan 87seeds with 50 mg/L GA₃ with pH 3.0 increased their stem height 0.59 cm and seedling height 0.40 cm. The priming treatment of MS K326 seeds with 50 mg/L GA₃ with pH 3.0 shorten their mean germination time 0.43 d, increased germination index 12.98%, seedling root length 0.28 cm, stem height 0.33 cm, and seedling height 0.61 cm. The priming treatment of hongda seeds with 50 mg/L GA₃ with pH 3.0 shorten mean germination time 0.36 d, increased germination index 10.82%, stem height 0.18 cm, and seedling height 0.43 cm. In conclusion, that pH value could influence priming effect, and the best pH value should be chosen when seeds were primed with GA₃.
