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 ...

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.

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.

Pollination ecology and breeding system of Ecbolium Ligustrinum (Acanthaceae): a transition from autogamy to xenogamy through specialised plant-pollinator interactions

Acta Botanica Hungarica, 2022
In view of the ongoing rarity ofEcbolium ligustrinumthere is an urgent need for conservation of the species. For this, a detailed work was carried out regarding the untold story of its reproductive ecology. The work was done for three consecutive years (2015–2017) at Midnapore, West Bengal over three different populations collected from three different
