The pollen morphology and ultrastructure of 20 species, representing eight genera of the Magnoliaceae are described based on observations with light, scanning and transmission electron microscopy.

Pollen Unit (Monad) Research study in pollen morphology conducted in DLSU-Dasma “Documentation and Identification of Pollen Found at DLSU-Dasma” (Bognot, et. (Recibido el 16 de Julio de 1986. 2, pp.

Pollen and seed germination tests can be used as effective test in screeing salt-tolerant crop and pollen grain morphology characteristics can be used to determine interspecific and intraspecific relationships among olive species. However, revisionary studies of its taxonomy and morphology are limited, and information about its species is mostly scattered in regional works. POLLEN MORPHOLOGY OF SELECTED BEE FORAGE PLANTS Shubharani, R., Roopa, P. & Sivaram, V. Laboratory of Biodiversity and Apiculture, Department of Botany, Bangalore University, Bangalore-560056, India ABSTRACT Pollen taxonomy is the prerequisite to compare the pollen present in honey samples with special reference to melissopalynological investigation. e rsidad de Barcelona. al,. Pollen morphology is one of the important tool for the taxonomic study of angiospermic plant groups. 43, No. The family represents a homogeneous group from a pollen morphological point of view. In many cases the aperture membranes are thickened and ' provided with characteristic cuticularized sculpturing. A study of pollen morphology could be useful to determine inter- and intraspecific relationships between olive species and can be important in olive fruit production. Studies of pollen morphology and taxonomy 351 Cookson and Erdtman (in Erdtman, 1952) they are 'rooted' 'just inside the exinous rims, between nexine and intine'. The pollen morphology of 16 species of aquatic angiosperms, distributed in 14 families from Karachi was examined by light and scanning microscope.

They survive grinding and aceto-lysis and, therefore, appear in the resultant palynograms.

Pollen morphology and its relationship to taxonomy of the genus Sarracenia (Sarraceniaceae) W. W. Oswald P 1,2 P, E. D. Doughty P 2 P, G. Ne’eman P 3 P, R. Ne’eman P 4 P, and A. M. Ellison P 2. 08028 Barcelona. Accpndo el 16 de Murzo de 1987) SUMMARY. Comparative study of pollen morphology and exine ultrastructure in tetrads, octads and polyads of the genus Mimosa (Leguminosae) Palynology: Vol. Our finding showed that the shape of pollen grain was similar (elliptical and trizonocolporate) but exine patterns and size of pollen grain were different in four olive cultivars. It is now widely used in the study of flora of many vegetations. Particularly in palynology, there are few studies that have included this genus, and usually only the most common species O. turpethum . 188-212.
