| Asexually. It pollinates itself. Asexual reproduction in plants is divided into two general types: vegetative reproduction and agamospermy. Vegetative reproduction refers to the formation of new plants by the growth of specialized structures that can survive after physical separation from the parent. Examples include growth by above- or below-ground stems (called stolons and rhizomes), and layering, in which the stem of a woody plant forms roots upon contact with the soil.
Asexual reproduction by seed, called agamospermy, occurs when a single parent plant forms seeds without pollination. Agamospermy thus differs from self-pollination, in which pollen produced by a plant fertilizes its own ovules. Asexually produced seeds also differ in their development from typical, sexually produced seeds. In some plants, maternal diploid cells (which, in a normal seed, do not contribute to the new embryo) divide via mitosis and overgrow the developing ovule. The seed produced is thus genetically identical to the parent plant. A number of tropical fruit trees, such as mangos (Mangifera spp.), can reproduce in this manner. |
