Female fertility in flowering plants is commonly observed to be submaximal. The fraction of ovules in a flower that produce seeds is commonly less than 1.00, particularly in outcrossing species. Here we investigate through controlled pollinations factors that may contribute toward low seed:ovule ratios in Trillium grandiflorum, a self‐incompatible woodland herb from eastern North America. Reduced fruit and seed set in open‐pollinated plants in comparison with hand cross‐pollinated plants… 
The interplay of pollination, costs of reproduction and plant size in maternal fertility limitation in perennial Paeonia officinalis
TLDR
The absence of any influence of pollen limitation or prior reproduction on seed production suggests that sub-maximal seed production in long-lived perennial herbs may be part of a size-dependent strategy that maximises life-time seed production and fitness without compromising survival.
Resource limitation and pollen source (self and outcross) affecting seed production in two louseworts, Pedicularis siphonantha and P. longiflora (Orobanchaceae)
TLDR
The results suggest that inbreeding depression in the two self-compatible species may also result in partial seed abortion under open pollination if mixed pollen is deposited on the stigma, and suggest that pollen interference plays an important role in low female fertility in theTwo Pedicularis species.
Style Persistence, Pollen Limitation, and Seed Set in the Common Prairie Plant Echinacea angustifolia (Asteraceae)

TLDR
The effect of pollen limitation, as quantified by SP, overrides the strong, fundamental relationship between fecundity and floret production and shows that populations consisting of large plants with large floral displays do not necessarily produce more seeds per plant.
S IT-AND-WAIT POLLINATION IN THE SPRING FLOWERING WOODLAND PLANT , T RILLIUM GRANDIFLORUM
In animal-pollinated plants, reproductive success is commonly limited by pollen availability, which can occur in environments where pollinator activity is scarce or variable. Extended floral
Reproductive Ecology of Trillium recurvatum (Trilliaceae) in Wisconsin
TLDR
It is demonstrated that pollen limitation is present in T. recurvatum but loss of habitat, habitat fragmentation and effects of distributional range limitation may not be discounted as forces influencing its rarity.
Reproductive Phenology and Pollination Biology of Madhuca Neriifolia in Wet Evergreen Forest of Western Ghats, South India
TLDR
Madhuca neriifolia is an endangered plant species occurring in the Southern Western Ghats of India that can support mixed type of pollination syndromes such as anemophily, entomophilies, ornithophily and chiropterophily.
Pollen limitation and resource limitation affect the reproductive success of Medicago sativa L.
TLDR
Outcrossing was dominant in the breeding system and insect pollination played an important role in outcrossing, which showed that pollen limitation was an important limiting factor for seed set in M. sativa.
Pollen limitation in a narrow endemic plant: geographical variation and driving factors
TLDR
The results indicate that E. popovii is pollen-limited in most of the populations studied, but only through seed production, since pollen supplementation did not enhance seedling emergence.
Morph Differences and Honeybee Morph Preference in the Distylous Species Fagopyrum esculentum Moench
TLDR
In controlled conditions, flowering phenology and flower morphology of the two floral morphs did not differ, indicating that factors other than floral morph or pollination events were governing female fertility in buckwheat.

Variation of pollen limitation in the early flowering Mediterranean geophyte Narcissus assoanus (Amaryllidaceae)
TLDR
While hand pollination significantly increased the seed:ovule ratio, the low value obtained indicates that the majority of ovules in flowers do not mature seeds despite handpollination, and the role of genetic and environmental factors governing low seed-ovule ratios in N. assoanus is discussed.
Sexual Selection in Raphanus sativus: Experimental Data on Nonrandom Fertilization, Maternal Choice, and Consequences of Multiple Paternity
TLDR
The paternity of seeds in the multiseeded fruits of R. sativus is determined and the consequences of microgametophytic competition among several pollen donors may be far more profound than competition among the male gametophytes produced by one pollen donor.
Effects of Leaf Removal on Reproductions vs. Belowground Storage in Trillium Grandiflorum
TLDR
Although the mean seasonal leaf conductance of partially defoliated plants was greater than that of intact plants, any compensatory increases in photosynthesis that may have occurred were apparently insufficient to prevent the reduced allocation to belowground storage.
The effect of pollination intensity and incompatible pollen on seed set in Turnera ulmifolia (Turneraceae)
TLDR
In both morphs, increasing amounts of pollen generally resulted in increased levels of seed set, although considerable variance was observed at all pollination intensities, which failed to detect a difference in the response of the floral morphs to pollination intensity.
REGULATION OF FRUIT AND SEED PRODUCTION IN AN ANNUAL LEGUME, CASSIA FASCICULATA'
TLDR
Variation in the number of fruit matured per inflorescence seemed to be related to variation in precipitation and plant survival through the fruit-filling period, and the data support both the second and third hypotheses.
Resource and Pollen Limitations to Lifetime Seed Production in a Natural Plant Population
TLDR
Both hand—pollination and fertilizing during the blooming season increased total seed production, while watering alone has no effect on any component of reproductive success.
Pollen Limitation and the Evolution of Self‐Compatibility in Linanthus (Polemoniaceae)
  • C. Goodwillie
  • Environmental Science
    International Journal of Plant Sciences
  • 2001
TLDR
Spatial variation in pollen limitation may explain why some lineages maintain outcrossing mechanisms whereas others evolve toward self‐fertilization, and why L. parviflorus and L. jepsonii remain self‐incompatible.
Stigmatic Self-Incompatibility and Mating Patterns in Trillium grandiflorum and Trillium erectum(Melanthiaceae)
TLDR
Structural studies of pollen traits indicated that the two species diAered with respect to the size of grains and their aggregation with implications for pollen dispersal and mating and the ecological and evolutionary implications of the variable expression of SI in Trillium are discussed.
Differential ovule development following self- and cross-pollination: the basis of self-sterility in Narcissus triandrus (Amaryllidaceae).
TLDR
Results indicate that self-sterility in N. triandrus operates prezygotically but does not involve differential pollen tube growth typical of many self-incompatibility (SI) systems, and it is hypothesize that this is due to the absence of a required stimulus for normal ovule development.
