Self-pollination ensures that even a smaller quantity of produced pollen grains from plants have a good success rate in pollination. The seeds produced may be poor in quality. Examples: Palms, papaya, cucumber, etc. Pollination of Cultivated Plants in the Tropics 111. In conclusion, despite having conservative floral traits, Manihot species can differ in their pollination biology, tending to Unisexuality: For a unisexual flower cross-pollination is the only possibility for fertilizing. Share This Article: Copy. P ollination is very important. Pollen: In a flower of a plant the Anthers of stamens produce a powdery material called pollen. J. Cross-pollination, also called allogamy, occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species.

ADVERTISEMENTS: In this article we will discuss about the types and agents of pollination. pollination usually leads to some degree of outcrossing and thus promotes and maintains genetic variation in populations, which in turn allows species to adapt to new and changing environments. 3670 Parental characters are preserved indefinitely. Upon transfer, the pollen germinates to form the pollen tube and the sperm for fertilizing the egg.
