Graphical comparison of the developmental stages of ovules inside E. aphyllum ovaries. Summary data for two seasons. Experimental checkpoints (0, 4, 8, 12 and 16 d) for six categories: immature female gametophyte (FG), from one- to four-nucleate (immature FG); mature female gametophyte (mature FG); a zygote (zygote) or zygote-like structure (zls); two-cell embryo (2-cell em); four-cell embryo (4-cell em); eight-cell embryo (8-cell em). The value above each bar indicates the number of ovules counted.
