Reproductive biology of Acacia senegal (L.) Willd.

The pollen morphological characters of seven accessions of the Acacia senegal (Mimosoideae) representing 456 plants were investigated for reproductive capacity. The different palynological parameters that have taxonomic significance were: Number of floral buds per inflorescence, Inflorescence length (cm), Pollen fertility percentage and Reproductive capacity recorded. This is a cross-pollinated plant, where the pollination process is being done by insect in mostly day time. The flower of this plant gives odor to attract the insects and the concentration of flower is very high during the season. A. senegal has a high degree of self-incompatibility which was also responsible for low fruit set ratio. It shows very low fruit set ratio which was less than one percent.
