All of the preceding chapters have been concerned with different aspects of sexual reproductive development in angiosperms (Fig. 1). In direct contrast, apomixis, the subject of this chapter is an asexual form of reproduction observed in some flowering plants. Generally, apomixis in plants refers to any form of asexual reproduction. The apomictic processes which will be considered here, however, give rise to fertile seeds. Paradoxically then, they are asexual reproductive events that occur within the ovule — a complex structure buried in the ovary compartment of the pistil (Fig. 1) which has evolved to carry out female sexual reproductive functions. |
