Comparative pollination role of stamens and breeding system in three species of Commelina (Commelinaceae) in Ile-Ife, Nigeria

Acta Botânica Brasílica, 2013
This study investigated pollination mechanisms and breeding systems in five Commelina variants: two subspecies of Commelina diffusa (C. diffusa subsp. aquatica and C. diffusa subsp. montana, each having two staminodes); two variants of C.

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).

Preventing self-fertilization: Insights from Ziziphus species

Frontiers in Plant Science, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

The Mating System of the Wild-to-Domesticated Complex of Gossypium hirsutum L. Is Mixed

Frontiers in Plant Science, 2018
The domestication syndrome of many plants includes changes in their mating systems. The evolution of the latter is shaped by ecological and genetic factors that are particular to an area.

Changes in Reproductive Traits in Physalis philadelphica; An Unexpected Shift Toward Self-Incompatibility in a Domesticated Annual Fruit Crop

Frontiers in Plant Science, 2021
Domestication is an evolutionary process with an impact on plant reproduction. Many domesticated plants are self-compatible (i.e., they lack mechanisms to reject their own pollen), but few domesticated plants are fully or partially self-incompatible.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Effect of different pollination schemes on the fruit morphometric characteristic of Vanilla planifolia Jacks.

Ornamental Horticulture
Vanilla planifolia Jacks. is an orchid of great economic interest, classified as endangered. The limited genetic variation of this species has been primarily attributed to its clonal propagation.

Multifaceted obscurity of Thismia abei (Thismiaceae): A fairy lantern with the protologue long disregarded in practice

PLANTS, PEOPLE, PLANET, EarlyView.
Tiny, leafless fairy lanterns are easily overlooked on the forest floor. Thismia abei, endemic to Japan, persists in small, unstable populations and is listed nationally as Critically Endangered. Our recent work has revealed another, less obvious form of obscurity.
