Cross-Pollination - Types of Pollination

In this kind of pollination the pollen from anther of one individual is transferred to the stigma of another individual of the same species. The process is mediated by physical or biological agents that include wind, water, insect, birds or mammals. Whereas, cross- pollination is obligatory in unisexual flowers, the bisexual flowers may have adaptations that prevent self-pollination. These adaptations involve:

  • Self sterility,
  • Dichogamy,
  • Herkogamy and
  • Heterostyl
