Abstract:
Pollen consists of different several characteristic which are shape, size, aperture, and wall
sculpture for each species. Four species have been choosing for the pollen characteristics
identification which is Rhizophora apiculata, Rhizophora mucronata, Avicennia alba and
Sonneratia caseolaris. The samples were obtained at Tum.pat Delta by taking their flower
for each species. The Scanning Electron Microscope (SEM), Inverted Microscope and
Light Microscope (LM) have been used to analyze the mo rphology of the pollen for each
species. The apertures characteristic resulting the three species which are Rhizophora
apiculata, Rhizophora mucronata and Avicennia alba shared the same types of apertures
which is tricolporate while the Sonneratia caseolaris is triporate due to the absent of the
colpi for that species. The similarities of Rhizophora apiculata, Rhizophora mucronata
and Avicennia alba also have been identified on the sculpture characteristic which is
reticulate but different for Sonneratia caseolaris species which is verrucate-psilate. Next,
the characteristic of the pollen shape is simile for both Rhizophoraceae species which is
triangular shape for polar view and prolate for equatorial view. The shape is different for
Avicennia alba that resulting triangular for polar view and prolate-spheroidal shape for
equatorial view while Sonneratia caseolaris circular for polar view and prolate shape for
equatorial view.
