The effects of incorporation SA into KNO3 priming solution on the germination and emergence of eggplant seeds at 15℃ were investigated.Seeds were primed into 3％ KNO3 containing 0.05,0.1,0.5,or 1 mM salicylic acid (SA) for 6 days,respectively.After the priming,seeds were either immediately used for germination and emergence test at 15℃ or stored at 4℃ for 1 month and then for the germination test.The primed eggplant seeds in general improved the final germination percentage (FGP),germination rate (Gso),and germination synchrony (E10-90) at 15℃ compared with non-priming seeds.Priming seeds in 3％ KNO3 solution supplement with 0.1 mM SA resulted in the best priming effect compared with other priming treatments and non-priming treatment,and all of the beneficial priming effects were still retained after stored at 4℃ for 30 days.These results indicated that priming seeds in 3％ KNO3 solution containing 0.1 mM SA could be used as an effective method to improve low-temperature performance of eggplant seeds and subsequent seedling growth.
