Self-pollination results in significantly lower seed set than cross-pollination in tristylous Narcissus triandrus. We investigated structural and functional aspects of pollen-pistil interactions and ovule-seed development following cross- and self-pollination to assess the timing and mechanism of self-sterility. Ovule development within an ovary was asynchronous at anthesis. There were no significant differences in pollen tube behavior following cross- vs. self-pollination during the first 6 d… Expand

TLDR
Variation in breeding systems among Cyrtanthus species is revealed and the potential for gender conflict in self-sterile species in which ovules are penetrated and disabled by pollen tubes from self-pollen is highlighted. Expand
Evidence for ovarian self-incompatibility as a cause of self-sterility in the relictual woody angiosperm, Pseudowintera axillaris (Winteraceae).
TLDR
Structural and functional aspects of pollen-carpel interactions and early seed development following cross- and self-pollination were investigated in P. axillaris to determine the site, timing and possible mechanisms of self-sterility, and results indicate that SI mechanisms inP. Expand
Evidence for Stigmatic Self-incompatibility, Pollination Induced Ovule Enlargement and Transmitting Tissue Exudates in the Paleoherb, Saururus cernuus L. (Saururaceae)
TLDR
The present study provides the first evidence in a primitive herbaceous species of stigmatic self-incompatibility (SI) in association with a dry stigma, pollination-induced signalling events aecting development of carpellary tissues, and micropylar exudates. Expand
Histological study of post-pollination events in Spathodea campanulata beauv. (Bignoniaceae), a species with late-acting self-incompatibility.
TLDR
Self pollen tubes grew successfully to the ovary, penetrating and fertilizing the majority of ovules by 48 h, indicating that S. campanulata is a species with late-acting self-incompatibility. Expand
Effects of self-, chase and mixed self/cross-pollinations on pistil longevity and fruit set in Ceiba species (Bombacaceae) with late-acting self-incompatibility.
TLDR
Extended floral longevity initiated with self-pollen tubes growing in the style indicates some kind of pollen tube-pistil interaction in Ceiba species known to have LSI. Expand
Emasculation increases seed set in the bird-pollinated hermaphrodite Kniphofia linearifolia (Xanthorrhoeaceae): evidence for sexual conflict?
TLDR
Results show that female performance in hermaphroditic flowers can be enhanced when flowers are emasculated, even if the overall number of pollinator visits is decreased. Expand
Pollination and late-acting self-incompatibility in Cyrtanthus breviflorus (Amaryllidaceae): implications for seed production.
TLDR
Evidence is added to growing evidence that seed production in plants with late-acting SI systems is frequently limited by pollen quality, even when pollinators are abundant. Expand
Early Ovule Development Following Self- and Cross-pollinations in Eucalyptus globulus Labill. ssp. globulus
TLDR
The mechanism of self-incompatibility appears to have both late pre- and post-zygotic components, and the number of healthy fertilized ovules was lower in both treatments compared with 4 weeks after pollination, and many ovules were degenerating. Expand
Early ovule development following self- and cross-pollinations in Eucalyptus globulus Labill. ssp. globulus.
TLDR
The mechanism of self-incompatibility appears to have both late pre- and post-zygotic components, and the number of healthy fertilized ovules was lower in both treatments compared with 4 weeks after pollination, and many ovules were degenerating. Expand
Self-Sterility in Camellia oleifera May Be Due to the Prezygotic Late-Acting Self-Incompatibility
TLDR
Results indicated that the self-sterility in C. oleifera may be caused by prezygotic late-acting self-incompatibility (LSI). Expand

The consequences of self-pollination in Asclepias exaltata, a self-incompatible milkweed
TLDR
The data strongly suggest that self- pollination in milkweeds not only wastes pollen but also greatly reduces the number of ovules and ovaries that might otherwise mature fruits and seeds after cross-pollination. Expand
AN ASSOCIATION BETWEEN VARIABILITY IN OVULE DEVELOPMENT WITHIN OVARIES AND SELF-INCOMPATIBILITY IN LOTUS (LEGUMINOSAE)
TLDR
The relationships of self-sterility to self-incompatibility in this genus, the evolution of this mechanism, and evidence that similar mechanisms are found in other legumes are discussed. Expand

Pollen—stigma interaction during sporophytic self-incompatibility in Brassica oleracea
TLDR
In both gametophytic and sporophytic multi-allelic systems, it is clear that SI involves a complex biochemical signalling system between the pollen grain (and/or the tube) and the pistil. Expand
Pollen tube growth in tristylous Pontederia cordata (Pontederiaceae)
TLDR
The observed differences in pollen tube growth of legitimate cross- and self-pollinations in P. cordata suggest that the species is primarily outbreeding, and the mechanisms of incompatibility may differ among the floral morphs and depend on the particular pollen size involved in pollinations.

TLDR
Ovules of Rhododendron kawakamii and R. retusum are anatropous, unitegmic, and tenuinucellate, with a typical eight-nucleate, seven-celled embryo sac, and fertilization normally occurs 4–5 days after pollination. Expand
