Figure 1: Anatomical changes in differentiating Sophora tonkinensis floral buds. (a) Illustrates the developmental course of Sophora tonkinensis in the “induction period” (I-III): Floral buds undifferentiated stage (i); preliminary stage of floral bud differentiation (II); Inflorescence differentiation stage (III). (b) Illustrates the developmental course of Sophora tonkinensis “differentiation period” formed by floral tissue (IV-VIII): Calyx differentiation stage (IV); corolla and pistil differentiation stage (v); stamen differentiation stage (VI); completion stage (VII, VIII). LP: Leaf primordium; IN: Inflorescence primordium; FL: Flower primordium; BR: Bract primordium; PE: Petal primordium; PP: Pistil primordium; SP: Stamen primordium; PS: Pollen sac; OL: Ovule; OV: Ovary
