Ecology and Evolution, Volume 15, Issue 9, September 2025.This paper analyzed the evolutionary potential of Ipomoea cavalcantei (an endemic species from the Amazon) by using floral integration and phenotypic selection analysis. The analyzed population presented floral integration in style length, probably due to selective pressures from pollinators on floral traits related to pollen deposition.

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

New Phytologist, Volume 247, Issue 6, Page 2733-2745, September 2025.Summary The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both. It has hitherto been difficult to uncouple the importance of these two hypotheses.

Time of flowering and fertilisation of quince varieties
International Journal of Horticultural Science, 1999 Literature dealing with flowering and fertilisation of quince is scarce. Most controversial and scanty are informations on observations of self- and cross-pollination.

The incidence and selection of multiple mating in plants.
, 2013 Mating with more than one pollen donor, or polyandry, is common in land plants. In flowering plants, polyandry occurs when the pollen from different potential sires is distributed among the fruits of a single individual, or when pollen from more than one

Investigations on self-compatibility and extent of self and cross pollination in cashew
, 2019 To address the issues of presence of self-incompatibility and extent of self and cross pollination in cashew, studies were carried out employing eight cultivars and four types of pollinations viz., self-pollination, geitonogamy, hand self-pollination ...
