Time course of reproduction in E. aphyllum. The occurrence of subsequent developmental stages of the ovules during experiments. At day 0 (start), flower buds (A) were treated according to the experimental variants (B–E). The indicated stages of female gametophytes and the subsequent fate of fertilized or unfertilized egg cells (zygotic embryogenesis or parthenogenesis) are marked with different colours. The presence of two neighbouring stages on the same day of the experiment is marked as a mix of the corresponding colours.
