STUDI VARIASI MORFOLOGI POLLEN PADA BEBERAPA SPESIES DARI GENUS HIBISCUS
Abstract: Genus Hibiscus is
one of genuses in Family of Malvaceae which is spread out through seed, and its
generative reproductive organ is flower. One part in flower are female
gametophyte (pistil) and male gametophyte (stamen) which produce pollen. Plants
that different species in same genus typically has different pollen. Variation
in pollen morphology can be used as one of the value in taxonomy. This aims of
research are investigating the variation of pollen’s layer morphology of some
Hibiscus species. The method of current
study is descriptive. Pollen which were investigated were from three species
and one cultivare of Hibiscus, such as Hibiscus rosa-sinensis Mary Forbes,
Hibiscus rosa-sinensis L. pink, Hibiscus rosa-sinensis L. yellow, Hibiscus tiliaceus
L., dan Hibiscus schizopetalus Hook. f. The method which was used to observe
pollen by SEM (Scanning Electron Microscope) with magnification 200x, 400x, and
1000x. Pollen has several characteristics which can be observed, such as
aperture, pollen shape, pollen size, and type of exine ornamental. The analysis
of data used descriptive qualitative.The result of this research showed that
pollen some species of Hibiscus showed some variation pollen characteristics.
P/E index of pollen 0.93 to 1.00, with the result the type of pollen shape are
oblat spheroidal. Pollen grain size between 100 µm to 175 µm, but it have same
type are permagna. The type of exine ornamental were echini, with different
type, the lengthiest of echini is 20.6 µm in Hibiscus tiliaceus L., the
withiest distance 40 µm of echini is Hibiscus rosa-sinensis L. yellow.
