Pollen Ultrastructure of Kopsia pauciflora Hook.f. var. pauciflora

Abstract

The Pollen grains are the male reproductive units of many types of plants. They vary in shape and ornamentation. The Morphology of pollen grains can be used for distinguishing species and cultivar in tree fruit species. Pollen morphology has been effectively applied in solving several problem of taxonomy. Pollen morphology also can be applied for various area, such as evolutionary studies, allergy studies, melissopalynology, forensic science, tracing plant geography, geology, climate change studies and study of past human impact on vegetation. Pollen morphology can be used for identification species. In this study, ultrastructure of pollen morphology of Kopsia pauciflora Hook.f. var. Pauciflora in Purwodadi Botanic Garden, was investigated using scanning electron microscope. Several morphological parameters including symetry, shape, size, aperture, also ornamentation shape. The type of pollen grains are monads, isopolar, sized 69.40 µm - 80.08 µm x 42.71 µm - 50.72 µm, shape prolate (P/E E 1.61-1.76). Their apertures are tricolporate. Pollen infolding, interaperture area sunken. The ornamentation is perforate.
