Pollen-pistil relationships and pollen size-number trade-off in species of the tribe Lycieae (Solanaceae)
(Springer Tokyo, 2002-12)
Pollen volume may be involved in different associations with other floral traits. Particularly, the literature indicates that pollen volume can be implicated in a functional relationship with pistil length, and that it may ...
High temperatures during late floral bud stages decrease fertilization in strawberry (Fragaria ₓ ananassa): pollen-pistil interaction and anatomical evidences
High temperature (HT) effects on pistil tissues and female gametophyte have been scarcely investigated in crops species. During strawberry flowering, HT can induce fruit malformations due to poor pollen performance in ...
Pollen load size, reproductive success and progeny kinship of natural pollinated flowers of the tropical dry forest tree, Pachira quinata (Bombacaceae)
(2001)
Several studies have demonstrated, using controlled pollinations, that the number and identity of pollen grains deposited onto a flower's stigma affect the reproductive success of plants. However, few studies have shown ...
Effects of self-, chase and mixed self/cross-pollinations on pistil longevity and fruit set in Ceiba species (Bombacaceae) with late-acting self-incompatibility
(Oxford University Press, 2004-08-01)
Background and aims Late-acting self-incompatibility (LSI). in which selfed flowers fail to form fruits despite apparently successful growth of the pollen tubes to the ovules, is a contentious and still poorly understood ...

Analysis of the Nicotiana tabacum Stigma/Style Transcriptome Reveals Gene Expression Differences between Wet and Dry Stigma Species
(Amer Soc Plant Biologists, 2009-03-01)
The success of plant reproduction depends on pollen-pistil interactions occurring at the stigma/style. These interactions vary depending on the stigma type: wet or dry. Tobacco (Nicotiana tabacum) represents a model of wet ...

Keeping up with the RALFs: how these small peptides control pollen–pistil interactions in Arabidopsis
(Wiley Blackwell Publishing, Inc, 2021-01-20)
The pollen and pistil RALF peptides, along with multiple receptor-like kinases and leucine-rich repeat extensins, regulate pollen tube growth and the final burst within the ovule, where sperm cells are released for ...
Strong but permeable barriers to gene exchange between sister species of Epidendrum
(Botanical Soc Amer Inc, 2016-08-01)
PREMISE OF THE STUDY: The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and how species integrity is maintained in the face of interspecific gene flow. ...
