POLLEN ULTRASTRUCTURE OF THEACEAE AND ITS SYSTEMATIC SIGNIFICANCE

Abstract

Abstract: The pollen of 50 or so species representing 17 genera of Theaceae was examined by light microscope, scanning electron microscope and transmission electron microscope for the pufpose to elucidate the systematic relationshipes of the family. The examination indicates that the pollen grains are 3-colporate basically,suboblate to spheroidal and a few to subprolate in shape, with size from 13- 50 pm(polar axis) x l3~ 55 pm(equatorial axis). The pollen sculpture can be divided in-to rugulate, granulate, reticulate, foveolate, spinulate, verrucate and psilate types etc. The exine consists of tectum, columellae, foot layer and endexine.

Key words: Teaceae, Pollen morphology, Systematic significance
