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

open access: yesOrnamental 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.

Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

Is there a hybridization barrier between Gentiana lutea color morphs? [PDF]

open access: yesPeerJ, 2015
In Gentiana lutea two varieties are described: G. lutea var. aurantiaca with orange corolla colors and G. lutea var. lutea with yellow corolla colors. Both color varieties co-occur in NW Spain, and pollinators select flower color in this species.

Not Only Hummingbirds: Reproductive Biology and Pollinators of the High-Andean Endangered Puya raimondii (Bromeliaceae)

open access: yesInternational Journal of Plant Biology
Puya raimondii, an endangered high-Andean species, exhibits life-history traits that may strongly influence its reproductive strategy; however, its reproductive biology remains poorly understood. Here, we assessed its floral biology, breeding system, and

Pollination by native bees increases fruit mass without changing protein content in snap beans [PDF]

open access: yesScientia Agricola
: Insects play a vital role in agricultural production by enhancing both the quantity and quality of fruits and seeds in a wide range of allogamous and autogamous crops. The common bean (Phaseolus vulgaris) exemplifies an autogamous crop that can benefit

The mixed mating system of a widespread weed: the case of Argemone ochroleuca Sweet (Papaveraceae)

open access: yesBotan‪ical Sciences, 2022
Background: Argemone ochroleuca is a worldwide invasive weed but is also highly valuable for their chemical compounds. Knowledge about its reproduction will help create plans for its control or its propagation. Questions: Does A.

Genomic Offset Analyses: Mind Your Climate Variables

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

The Ability of Spontaneous Autogamy in Four Orchid Species: Cephalanthera Rubra, Neottia Ovata, Gymnadenia Conopsea, and Platanthera Bifolia

open access: yes, 2017
The breeding system in Orchidaceae generates many questions about the selfing potential of its representatives. We investigated the ability of spontaneous autogamy of four orchid species: Cephalanthera rubra and Neottia ovata of the Neottieae tribe and ...

Adaptive floral traits that impact stigma pollen load and seed production in Penstemon digitalis (Plantaginaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.
