Pollen morphology of the alangiaceae [PDF]
Review of Palaeobotany and Palynology, 1970 This paper presents a pollen-morphological study of Alangium, a genus mainly restricted to the tropics of the Old World, of which 18 of the 19 known species were studied. The pollen grains, studied with the use of a light microscope, a transmission electron microscope and a scanning electron microscope, were classified into 15 pollen types, to which a ...

Advanced Functional Materials, EarlyView.Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Pollen Morphology and Sucrose Giving on Stigma Relation with Incompability of Sweetpotato (Ipomoea Batatas (L.) L.) [PDF]
, 2013 The purpose of the research is to examine how to increase cross and self-pollination by solving incompatibility of sweet potato mechanism through sucrose giving on stigma and pollen nuclei checking. Sucrose in different concentration is giving to stigma.

The True Identity of the “Second Pollen Morphology” of Camellia oleifera—Stomium Cells
Horticulturae, 2022 Previous studies on Camellia oleifera pollen morphology have indicated dual morphologies, defined as “dimorphism”. However, they were limited to morphological studies at the end of final development and did not elucidate the origin, structure, and ...
