• Pollination does not nahi the transfer of the right type pollen. Often, pollen of the wrong type, either from other species Or from the same plants, also land of the stigma.

• The pistil has to ability to recognise the pollen, whether it is of the right type or of the wrong type. If it is of the right type the pistil accepts the pollen and promotes post - pollination events that leads to fertilization.

• If pollen is of wrong type the pistil reject the pollen by preventing pollen germination on the stigma or the pollen tube growth in the style.

• Rejection is outcome of a continuous which dialogue between grain and the pistil. The dialogue is mediated by chemical components of the pollen.
