Histogenesis of the transmitting tract in Strelitzia reginae
Nordic Journal of Botany, 2001Organisation and development of the stigmatic, stylar and ovarian parts of the transmitting tract in Strelitzia reginae were evaluated. They were characterised by 1) cell shape, 2) appearance of distal cell wall, 3) type of plastid, 4) and vacuolar system.

Anatomy of the Strelitzia reginae flower (Strelitziaceae)
Nordic Journal of Botany, 1986The Strelitzia reginae Ait. flower has many remarkable structural spezializations, the histology and cytology of which we have investigated. The chromoplasts of the sepals are conspicuously elongated and enclose numerous carotenoid tubules parallel to the ...

Thread–like formations in the anthers of Strelitzia reginae
Nordic Journal of Botany, 1981In the dehiscent anthers of Strelitzia reginae Ait. thread–like formations occur among the pollen grains. The threads are derived from specialized epidermal cells in the stomium region. These cells are liberated from the normal epidermal cells and from each other along their radial walls.

The nectar of the Strelitzia reginae flower
Physiologia Plantarum, 1989The nectar of Strelitzia reginae Ait. was analysed using enzymatic methods and found to contain glucose, fructose and sucrose. Sugar composition changed considerably over the nectar producing period: there was an increase in the amount of glucose (41%) and fructose (32%) between the early and middle stage of secretion and thereafter a decrease of 13 ...

Strelitzia reginae Leaf as a Natural Template for Anisotropic Wetting and Superhydrophobicity
Langmuir, 2012Artificial surfaces that exhibit unidirectional water spreading and superhydrophobicity are obtained by Strelitzia reginae leaves. Both green and dried leaves are used, thus exploiting the plant senescence. We demonstrate that the natural drying process of the leaves strongly affects the surface morphology and wettability.

Pollen Grain Development and Tapetal Changes in Strelitzia Reginae (Strelitziaceae)
American Journal of Botany, 1989The proexine that forms within the callosic envelope before the end of the microspore tetrad period is thick (about 1 μm) and exceptionally complex. It has components equatable with tectum, columellae, and a nexine that includes lamellar zones. All these components persist in the exine although late in development they become difficult to recognize ...
