Pollination: Self-fertilization strategy in an orchid

  author={Ke-wei Liu and Zhong-Jian Liu and Laiqiang Huang and Liqiang Li and Li-jun Chen and Guang-da Tang},
Mating in flowering plants normally relies on animals, wind, gravity or secretion to convey pollen grains from the male (anther) to the female (stigma) organ. Here we describe a new type of self-pollination mechanism in the tree-living orchid Holcoglossum amesianum, in which the bisexual flower turns its anther against gravity through 360° in order to insert pollen into its own stigma cavity — without the aid of any pollinating agent or medium. This mode of self-pollination, which occurs under… Expand
The Anther Steps onto the Stigma for Self-Fertilization in a Slipper Orchid
The mode of self-pollination discussed here is a new addition to the broad range of genetic and morphological mechanisms that have evolved in flowering plants to ensure their reproductive success. Expand
Orchid mating: the anther steps onto the stigma
The mode of pollination in Paphiopedilum parishii is a new addition to the broad range of genetic and morphological mechanisms that have evolved in flowering plants to ensure their reproductive success and is a possible adaptation to the insect-scarce habitat of the orchid. Expand
A floral organ moving like a caterpillar for pollinating
Abstract  A new pollination mechanism is reported of an orchid species, Bulbophyllum penicillium, based on a field observation in Southeast Yunnan of China. This species has a sensitive lip, andExpand
Rain pollination provides reproductive assurance in a deceptive orchid.
Ombrophily in the deceptive orchid Acampe rigida is investigated to determine the mechanism by which this species is able to maintain high fecundity, despite flowering during the rainy season in south-west China when pollinators are scarce. Expand
Growth discrepancy between filament and style facilitates self‐fertilization in Brandisia hancei (Paulowniaceae)
Evidence is presented for an autonomous self-fertilization mechanism in the winter flowering plant, Brandisia hancei, which seems to be an adaptive strategy to ensure reproduction when pollinators are scarce. Expand
Wind-dragged corolla enhances self-pollination: a new mechanism of delayed self-pollination.
This delayed self-pollination, which involved the movement of floral parts, the active participation of the wind and sensitive stigma, is quite different from that reported previously and provides reproductive assurance for this species. Expand
Slow stamen movement in a perennial herb decreases male–male and male–female interference
This study suggested that slow stamen movement in Lychnis cognata presents pollen gradually to pollinators, representing an adaptation to decrease interference between dehisced and dehiscing anthersExpand
Autogamous seed set in a critically endangered orchid in Japan: pollination studies for the conservation of Nervilia nipponica

Investigation of the pollination biology of the critically endangered Nervilia nipponica revealed that, in open-pollinated plants, pollen grains germinate within the anther on the first day of anthesis, and that fertilisation occurs within the following 96 hours, suggesting efficient, non-mechanical autopollination.

Autonomous self-pollination in the South African orchid Satyrium rupestre Schltr.
Evidence of autonomous self-pollination in S. rupestre flowers, scent emission rates and the number of massulae per pollinium are consistent with reduced reliance on animal pollinators, and future studies should focus on the extent to which the species relies on autonomousSelf- pollination for reproduction.

A comparative investigation into the breeding system of two fully mycoheterotrophic orchids, Cymbidium macrorhizon and C. lancifolium, finds autogamy would likely be favoured as a reproductive assurance to compensate for pollinator limitation due to their lack of nectar and pollinators’ hostile habitat preferences.

Results show that evolution of inbreeding by natural selection for reproductive assurance is possible in Mimulus, and illustrate the complex changes in floral dynamics and morphology it may involve. Expand
Genetic cost of reproductive assurance in a self-fertilizing plant
It is shown that, during 2 years in 10 Ontario populations of Aquilegia canadensis (Ranunculaceae), reproductive assurance through self-fertilization increases seed production, but this benefit is greatly outweighed by severe seed discounting and inbreeding depression. Expand
A high rate of self-fertilization and increased seed fertility of homostyle primroses
It is shown that the self-fertile homostyle variant of the primrose Primula vulgaris, which reaches high frequencies in certain populations11, experiences a fertility advantage, in terms of seeds per plant, as a result of its high rate of self-Fertilization. Expand
The Evolutionary Enigma of Mixed Mating Systems in Plants: Occurrence, Theoretical Explanations, and Empirical Evidence
▪ Abstract Mixed mating, in which hermaphrodite plant species reproduce by both self- and cross-fertilization, presents a challenging problem for evolutionary biologists. Theory suggests thatExpand

Evidence is presented to show that the CL flowers have modifications in their development which ensure self pollination, and a proposal is made for using this phenomenon of dimorphic flower production as a system for the study of floral morphogenesis, function and evolution. Expand

Differences in the frequency with which offspring are produced asexually, through self-fertilization and through sexual outcrossing, are a predominant influence on the genetic structure of plant populations and suggest that selfing and asexual lineages may be evolutionarily short-lived. Expand

Botany: A new self-pollination mechanism
A new process for self-pollination in the laterally orientated flowers of a Chinese herb is discovered, in which a film of pollen is transported from the anther (pollen sacs) by an oily emulsion that slides sideways along the flower's style and into the individual's own stigma. Expand
