Various types of pollination occur in seed plants.
As to plant-to-plant pollen transfer, two types exist self-pollination and cross-pollination.
Classification has also been made according to agents of pollination.
Having a sufficient understanding of these pollination mechanisms is important in crop agriculture.
Knowing the normal mode of pollination of any crop can accelerate crop improvement works because plant breeding methods are pollination type-dependent.
Proper cultural management practices, such as in relation to pests and diseases control and biodiversity, can be identified to favor populations of animal pollinators.
The process of pollination precedes fruit and seed formation in the angiosperms and seed formation in the gymnosperms.
Both fruits and seeds perform functions in plant reproduction. In particular, the seeds serve as the major, immediate, direct progenitors of new plants.
In addition, many agricultural crops are grown for the primary purpose of producing either fruits or seeds or both.
