滇杨侧芽不同季节内源激素含量变化动态

植物内源激素在植物体内含量甚微,也往往不是由一个器官产生,却通过极性和非极性运输到达一定的部位而产生重要的作用[1],它们参与各细胞、组织和器官之间的信息交流,从而维持植物正常的生长发育过程[2]。高等植物通过顶端分生组织和侧生分生组织的活性来建立地上株型系统,而植物激素作为整合调控分生组织信号的使者,与植物株型的形成密切相关[3]。...

Summary:植物内源激素在植物体内含量甚微,也往往不是由一个器官产生,却通过极性和非极性运输到达一定的部位而产生重要的作用[1],它们参与各细胞、组织和器官之间的信息交流,从而维持植物正常的生长发育过程[2]。高等植物通过顶端分生组织和侧生分生组织的活性来建立地上株型系统,而植物激素作为整合调控分生组织信号的使者,与植物株型的形成密切相关[3]。

lateral buds of Populus yunnanensis ; ABA ; IAA ; ZR ; content changes
In order to understand the content changes of endogenous hormones in lateral buds of Poptdus yunnanen- s/s during different seasons, the lateral buds collected from stems of three-year old cuttings of P. yunnanensis were used as materials, contents of ABA, IAA and ZR in the lateral buds in the autumn, winter and spring were detected by enzyme-linked immunosorbent assays (ELISA). The results indicated that the contents of ABA and IAA were first decreased and then increased while the contents of ZR increased gradually, and th
