Pollen morphology

Study of morphological characters of pollen grains of particular region is useful for the identification and classification of local plants and identification of atmospheric pollen. The conclusions on present study on plants belonging to 73 families, 229 genera and 279 species are being discussed here.28 out of total 73 families studied in this work are found important. 28 out of total 73 families studied in this work are found important. Analysis of major Eurypalynous families of the irrigated region is carried out.

The pollen morphology of 5 Jatropha species namely J. glandulifera, J. gossypifolia, J. integerrima, J. multifida and J. tanjorensis of family Euphorbiaceae from India was studied using Light Microscope (LM). The pollen grains of Jatropha are typically crotonoid, uniformly spheroidal, in aperturate/omniaperturate, with hexagonally arranged exinous knobs.
