Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Reproductive assurance through autogamous self-pollination across diverse sexual and breeding systems [PDF]

open access: yes, 2015
Pollination becomes a constraint when conspecific plants and/or their pollinators become scarce. Many plant species have evolved autogamous self-pollination as a means of reproductive assurance (RA) under pollination-uncertain environments. So far RA has

Notes on the self-pollination in Dendrobium biflorum (Orchidales, Dendrobiinae)

open access: yesActa Societatis Botanicorum Poloniae, 2012
The conditions favouring self-pollination are determined for a species of Dendrobium Sw. A survey of gynostemium micro­morphology in collected flowers of Dendrobium biflorum revealed two stages of a unique form of autogamy: on germination of pollen ...

Transfer of Self-Fruitfulness to Cultivated Almond from Peach and Wild Almond

open access: yesHorticulturae, 2022
The almond [Prunus dulcis (Mill.) D.A. Webb] is normally self-sterile, requiring orchard placement of pollinizer cultivars and insect pollinators. Honeybees are the primary insect pollinators utilized, but climate change and the higher frequency of ...

Investigation of the Breeding Mechanism of African Yam Bean [Fabaceae] (Sphenostylis stenocarpa Hochst. Ex. A. Rich) Harms

open access: yesNotulae Scientia Biologicae, 2018
The many reported inherent nutritional potential in African yam bean (Sphenostylis stenocarpa (Hochst. Ex. A. Rich.) Harms) seem to provide platform for the need of its genetic improvement.

Genetic variability and selection criteria of some sunflower genotypes under different pollination methods

open access: yesActa Agriculturae Slovenica, 2020
To determinate self-compatible genotypes for increasing autogamy yielded, the ten sunflower genotypes were sown under four pollination methods i.e., open-, self-, hand- and sib-pollinations in a randomized complete block design replicated thrice at Kafr ...

Comparative reproduction mechanisms of three species of Ocimum L. (Lamiaceae)

open access: yesActa Agrobotanica, 2016
Ocimum species have a combination of reproductive system which varies with the locality and cultivar. We have studied here the reproductive mechanisms of five variants of three Ocimum species in Nigeria, namely: Ocimum canum Sims., O. basilicum L., and O.

The dark side of the rain: self-pollination setbacks due to water exposure in Pavonia varians Moric (Malvaceae), a species with rain-dependent flowering [PDF]

open access: yesActa Botânica Brasílica, 2020
Plants that occur in arid or semi-arid environments may restrict their flowering to the rainy season to ensure water availability for reproductive functions. However, the exposure of flowers to rainfall can compromise their functionality, such as complex
