Figure 3. Anatomical structures of tentpole during development. (A) Cells at micropylar end of female gametophyte at ~55 d after pollination. (B) Tentpole at ~110 d after pollination, with starch grains beginning to accumulate. (C) Surface cells of tentpole at ~120 d after pollination. (D) Inner cells of tentpole at ~120 d after pollination. (E) Tentpole cells at ~130 d after pollination. (F) Finger-like surface cells of tentpole. (G) Regularly arranged surface cells of tentpole. (H) Tentpole cells after fertilization. (I) Tentpole cells at harvest time. N, Nuclei; S, Starch grain. Scale Bar = 20 μm.
