The characteristics of mangrove's life pollen for exclusive species at Tumpat, Kelantan

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.
