Floral syndrome and breeding system of the spring flowering plant Iris scariosa (Iridaceae)

Guangxi Zhiwu
Iris scariosa is a perennial spring flowering Iridaceae species with important ornamental value. To explore the floral syndrome and breeding system and promote the utilization of this germplasm, flowering phenology, floral syndrome, breeding system and ...

Reproductive biology aspects of two species of the genus Gavilea (Orchidaceae, Chloraeinae) in populations from Central Chile Aspectos de la biología reproductiva de dos especies del género Gavilea (Orchidaceae, Chloraeinae) en poblaciones de Chile central

Gayana: Botanica, 2010
The extent to which plants depend on pollinators for outcross pollen transportation is a key issue in plant reproductive ecology. We evaluated the putative breeding system, foral display, and natural pollination in two Southern Cone of South American ...

Obesity: A reckoning both for genetic immunity to infection and xenogamy

Medical Hypotheses, 2006
It is hypothesized that the genesis and spread of obesity is predetermined by genetic immunity to infections and subsequent interethnic genetic admixture. As in genetic immunity to infections, obesity is determined by a constitutional incongruence between relevant acting agents and their molecular targets.

Morphological, Phenological, and Pollen-Distribution Evidence of Autogamy and Xenogamy in Gilia achilleifolia (Polemoniaceae)

Systematic Botany, 1977
In three populations of Gilia achilleifoliafloral morphological and phenological characters and pollen distribution on stigmas suggest that different breeding systems are associated with the two main races of the species. The shade race has small corollas, stigmas maturing below the anthers, low pollen production, low pollen-ovule ratios, homogamy ...

Anthecology and reproductive system of Mourera fluviatilis (Podostemaceae): Pollination by bees and xenogamy in a predominantly anemophilous and autogamous family?

Aquatic Botany, 2011
Abstract The Podostemaceae are sessile hydrophytes restricted to habitats with waterfalls and seasonal flow variability. Mourera fluviatilis belongs to the family and has a disjunct distribution in the Amazon and northeastern Brazil. The following hypotheses were tested: (i) both autogamy and anemophily act on the pollination system of M ...

On the Role of Xenogamy in the Development of Life Strategy for Fragaria vesca L. in Western Siberia

Contemporary Problems of Ecology, 2019
A combination of xenogamy and autogamy in the breeding system is typical for natural Fragaria vesca L. populations. A natural experiment has been conducted to clarify the portion of xenogamy. During flowering, the plants of inbred line no. 08-2, marked by recessive c allele (light yellow colored berry), are placed in native populations of wood ...

Induced xenogamy enhances capsule formation, seed viability, in vitro seed germination, and seedling growth in the threatened orchid Diplomeris hirsuta: A strategy for conservation

Journal of Applied Horticulture
Diplomeris hirsuta, a medicinally important yet threatened terrestrial orchid species, is vulnerable to extinction as per the IUCN Red List. This study aimed to investigate the influence of different pollination methods on D. hirsuta seed viability, seed germination in tissue culture media and their subsequent plant growth.
