Pollen morphology of selected true mangrove species in Kerala


S Surya, N Hari

A study on pollen morphology of fifteen common Indian mangroves from Kerala mangrove swamps. Pollen consists of 9 genera and 15 species belongs to 10 families of true mangrove species has been investigated by light microscope and scanning electron microscope. In present study all the taxa showed few variations based on the characteristics of apertures, ornamentation, size and shape. Through this study gives rise to an idea about pollen type of true mangrove flora in Kerala. Different pollen shapes encountered are Oblate-Spheroidal to Perprolate. Pollen grains were 3-colpate in Acanthus, 3-colporate in Aegiceras, Avicennia, Bruguiera, Excoecaria, Kandelia, Rhizophora and Lumnitzera, 3-pororate in Sonneratia. Exine ornamentation, size and shape of pollen grains are also taken into consider supplementary characters. Present study concluded that most primitive 3-colpate pollen occurs in Acanthaceae; while 3-colporate in five families and the most advanced porate condition in Sonneratiaceae. It appears that aperture evolution has most operated in Acanthaceae followed by Sonneratiaceae.
