Figure 5
Histological structure of embryo and germination of mature seeds.
(A). Longitudinal sections of control embryo at 7DAP. (B, C) Longitudinal sections of embryo of s-seeds (B) and m-seeds (C) at 7 DAP, respectively. (D). The normally germinated seed of control plant. (E). Longitudinal sections of the mature embryo in control seed. The red line referred to the position of vascular bundle. (F). Magnifying observation of cross sections from the red line marked parts in (E). The arrow showed the clear vascular bundle. (G). The m-seeds failed to germinate. (H). Longitudinal sections of the mature embryo in m-seeds. (I). Magnifying observation of cross sections from the red line marked parts in (H). No obvious vascular bundles were observed at the arrow referred place. VB, vascular bundles. Bars = 20 µm in (A–C), 5 mm in (D) and (G), 0.2 mm in (E) and (H), 20 µm in (F) and (I).
