Increased aperture number in angiosperm pollen grains offers a potential selective
advantage because it increases the number of prospective germination sites, thus facilitating …

Pollen germination is a prerequisite for double fertilization of flowering plants. A
comprehensive understanding of the structural and molecular basis of pollen germination …

This paper critically reviews the distribution of microsporogenesis types in relation to recent
concepts in monocot systematics. Two basic types of microsporogenesis are generally …

Microsporogenesis is highly labile in early-branching angiosperms, ie, those with mostly
sulcate pollen, compared with the tricolpate and tricolpate-derived eudicots. New records of …

The pollen morphology of 11 genera and 11 species of the Hydrocharitaceae and one
species of the Najadaceae was studied using scanning and transmission electron …

Liliales are a relatively well-defined order, effectively distinguished from Asparagales and
Dioscoreales by the consistent absence of septal nectaries and other more homoplasious …

For a monocotyledonous family, the Arecaceae possess unusually varied pollen, not only in
aperture number and orientation, but also in exine ornamentation. Although the majority of …

Qualities of the stratified pollen walls were evaluated for their possible role in pollination
(pollination modes, and pollen tube formation). The importance of studying pollen grains in …

In this study 12 species of Cyperaceae have been studied for quantitative and qualitative
observation of pollen grains through Light and scanning electron microscopy. Pollens of 12 …
