Self-fertility studies of some sweet cherry (Prunus avium L.) cultivars and selections
International Journal of Horticultural Science, 2004 Fruit set of two sweet cherry cultivars (Alex' and 'Stella' ) and four Hungarian selections have been studied over two years following open pollination, unassisted self-pollination (autogamy) and artificial self-pollination (geitonogamy).

Pollination boilogy and breeding system of Eugenia discifera Gamble An endangered species of Western Ghats, India. [PDF]
, 2015 Knowledge of the pollination biology and breeding systems is very important for understanding the life history of long - lived tree species. In case of endangered species, the information may have implication for conservation practices.

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations
Biotropica, Volume 57, Issue 6, November 2025.In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Are tetraploids more successful? Floral signals, reproductive success and floral isolation in mixed-ploidy populations of a terrestrial orchid [PDF]
, 2017 Background and Aims Polyploidization, the doubling of chromosome sets, is common in angiosperms and has a range of evolutionary consequences. Newly formed polyploid lineages are reproductively isolated from their diploid progenitors due to triploid ...

Journal of Integrative Plant Biology, Volume 67, Issue 11, Page 2945-2963, November 2025.Examining data from 148 Bambusoideae and Pooideae species showed elevated protein evolution rates in highly cloned woody bamboos, providing evidence for an association between protein evolution and life‐history traits in plants with contrasting reproductive modes. ABSTRACT Rates of protein evolution (dN/dS) vary widely across the tree of life.

Incidence, correlates, and origins of dioecy in the Island Flora of New Caledonia [PDF]
, 2014 Premise of research. Because it is an inherently risky sexual system, dioecy is globally rare. Attempts to explain unusually high incidences of dioecy on certain islands have generated a considerable literature on the relationships among dioecy, its ...

Functional Significance of Labellum Pattern Variation in a Sexually Deceptive Orchid (Ophrys heldreichii): Evidence of Individual Signature Learning Effects. [PDF]
PLoS ONE, 2015 Mimicking female insects to attract male pollinators is an important strategy in sexually deceptive orchids of the genus Ophrys, and some species possess flowers with conspicuous labellum patterns.
