ABSTRACT

Pollen morphology of ten woody plant species was carried out using light microscope. The study adopted Erdtman method of pollen analysis. Pollen characters studied are pollen shape, aperture type, surface pattern, pollen size, and grain arrangement. The result revealed that 50% of the species accounted for Tricolporate class, 30 % for triporate class, 10 % each for tricolpate and pantoporate classes. 50% of the species accounted for reticulate exine pattern, 20% for psilate, while 10% each accounted for baculate, granulate and echinate pattern. Result of pollen shape indicates that 50% of the species accounted for prolate-spheroidal, 20% for suboblate and 10% each for spheroidal, oblate and peroblate shapes. 40% of the species accounted for medium size pollen, 30% small size pollen, 20% large pollen and 10% for very large pollen. All the species were observed to possessed monad grain arrangement. Variations observed in the morphology of the studied species revealed pollen characters that can be reliably used to separate and delineate taxa.
