摘　　要：以茎瘤芥老化种子为实验材料,选用聚乙二醇6000、硝酸钾、氯化钠、聚乙烯醇及水杨酸5种渗调剂和蒸馏水(ck)进行处理种子,研究各种渗调剂的处理效果。结果表明,5种渗调剂处理种子后,种子发芽率、发芽势、发芽指数、活力指数、淀粉酶活性和过氧化物酶活性均比蒸馏水处理效果好。其中,聚乙二醇6000处理效果最好,且与其余4种渗调剂及蒸馏水的处理效果均有极显著差异(p<0.01)。The aged seeds were osmoticly primed by solutions of polyethylene glycol 6000,potassium nitrate,sodium chloride,polyvinyl alcohol,salicylic acid and distilled water respectively to analyze their osmotic priming effects.The results showed that seeds vigor parameters,such as germination percentages,germination trends,germination index and vigor index were higher than that of the control after osmotic priming,and primed by the solution of polyethylene glycol 6000 osmotic had the best effect and highly significant differences with the others（p0.01）.
