Morphological characteristics of walnut female flower buds. (A–C) show the female flower buds in the predifferentiation period identified in the undifferentiated stage (F_1); (D–F) show the female flower buds in the initial differentiation period (F_2); (G–I) show the female flower buds identified at the flower primordium differentiation period (F_3); (J–L) show the leaf buds (JRL) collected at the same stage of F_2. (A,D,G,J) are images of paraffin sections with a 100 μm scale bar; (B,E,H,K) are images of paraffin sections with a 50 μm scale bar; (C,F,I,L) show the external morphology of the buds at different stages with a 1 mm scale bar.
