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 ...
Influence of flower functionality and pollination system on the pollen size-pistil length relationship
(Elsevier Gmbh, 2009-05)
Twenty-five biotically pollinated plants of the Chaco Serrano Forest (Córdoba, Argentina) were studied in order to analyze whether ‘flower functionality’ is related to the relationship between pollen size and pistil length. ...
Pollen size and pistil length variation: the influence of flower-functionality and pollination system
(Springer Heidelberg, 2009-06-25)
Twenty-five biotically pollinated plants of the Chaco Serrano Forest (Córdoba, Argentina) were studied in order to analyze whether ‘flower functionality’ is related to the relationship between pollen size and pistil length. ...
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 ...
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 ...

Evidence for post-zygotic self-incompatibility in Handroanthus impetiginosus (Bignoniaceae)
(Springer, 2017-06-01)
Late-acting self-incompatibility (LSI) has been defined as a genetically controlled self-sterility mechanism that prevents seed set by selfing, despite normal pollen tube growth and ovule penetration in self-pollinated ...
