(ii) Continued self-pollination result in inbreeding depression.
(iii) If both male and female flowers are present on the same plant such as castor and maize, it prevents both autogamy and geitonogamy.
(iv) The pistil has the ability to recognize the pollen, whether it is compatible or incompatible.
(v) The pollen grain germinated on the stigma to produce a pollen tube through one of the germ pore.
(vi) Pollen tube, after reaching the ovary enters the ovule through the chalaza and then enters one of the synergids through the filiform apparatus.
(vii) All the events-from pollen deposition on the stigma until pollen tubes enter the ovule-are together referred to as pollen-pistil interaction.
(viii) If the female parent bears bisexual flowers, removal of anthers from the flower bud is necessary, before the anther dehisces. It is done by using a pair of forceps. This step is referred to as emasculation.
(ix) After entering one for the synergids, pollen tube releases one male gametes into the cytoplasm of synergid.
(x) The male gamete fuses with two polar nuclei located in the central cell produce a triploid primary endosperm nucleus.
(xi) The formation of PEN involves fusion of 2 haploid nuclei, which is termed double fusion.
