摘　　要：为了揭示NaOH处理打破紫椴种子休眠的效果,测定了NaOH处理后紫椴种子层积过程中内源激素含量的变化。结果表明:打破休眠期间,NaOH处理后ABA含量不断下降,IAA在打破休眠初期急剧上升,GA含量也不断上升;GA/ABA比值表现为一直上升,IAA/ABA比值在打破休眠初期也呈大幅上升。说明NaOH处理促进了紫椴种子打破休眠过程中期间内源激素反应的速度。In order to reveal effects of endogenous hormone of germination of Tilia amurensis seeds by NaOH,the dynamic changes of endogenous hormone in the process of germination of overcoming dormancy in Tilia amurensis.Result shows that:Compared with control,ABA declined rapidly after germination,GA&IAA content increase.GA/ABA and IAA/ABA are increase.NaOH treatments were used to break seed coat barrier and change reactions of endogenous hormone in Tilia amurensis seeds effectively.
