Figure 2: Morphological analysis of differentiating Sophora tonkinensis floral buds. (a) Floral buds undifferentiated stage: A large nucleus and vacuoles, an obvious nucleolus and many starch granules (bar = 5 μm); (b-d) the change of the vacuole and starch granules as differentiating floral buds progresses: (b) vacuole and starch granules reducing (bar = 2 μm); (c) small vacuoles and starch granules (bar = 2 μm); (d) volume was reduced and vacuoles and starch granules gradually disappeared (bar = 2 μm). SG: Starch granules; V: Vacuoles
