Abstract：The seeds of eggplant rootstock ('Torvum') are difficult to germinate.In this study,the primed seeds were used as materials,the effects of different priming methods (KNO3,CaCl2,NaCl,GA3) and dehydration or not on vigour and germination of'Torvum'seeds were investigated.The results showed that the seeds germination ability (21.39) and seeds vigor index (160.84) were significantly improved under GA3 treatment,which were 37.59％ and 118.50％ higher than CK respectively.Seeds germination ability and seeds vigor index were not affected by dehydration,the seeds could be sowed directly after GA3treatment without dehydration.The efficiencies of KNO3,CaCl2 and NaCl treatment could be promoted by dehydration,and KNO3 exhibited the best effect on the germination index(15.68) and vigor index(136.68),which were 14.86％and 42.35％ higher than CK respectively.There was no significant difference between CaCl2 and NaCl treatments,the germination indexes were 15.76,16.09,and the vigor indexes were 124.47 and 124.38 respectively.
