Bearing style and flower bud differentiation in Ficus carica L. (A) Fig fruit (‘Houraishi’) production in Japan. The broken arrow indicates the period when inflorescences differentiate but most resulting fruits drop or decay because of winter low temperature. (B) First-crop fruits differentiate at nodes near the tip of 2-year-old pre-fruit-bearing branches (black arrows) and second-crop fruits differentiate at nodes near the base of 1-year-old fruit-bearing branches (white arrows). Inflorescences differentiate sequentially from lower nodes as a 1-year-old fruit-bearing branch develops. (C) Exterior appearance of leaf bud (left white arrowhead) and flower bud (right black arrowhead) at axillary position. (D) Histological sections of apical bud meristem (api). No inflorescences were observed before bud flushing. (E) Histological sections of a flower bud with an early receptacle (ere) and scales (sc). (F) Histological sections of a flower bud with a flat receptacle (fre) and scales (sc). (G) Histological sections of a flower bud with a curved receptacle (cre) surface on which floret (fl) differentiation begins. Bar = 500 μm.
