ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Avoiding sexual interference: herkogamy and dichogamy in style dimorphic flowers of Narcissus broussonetii (Amaryllidaceae) [PDF]
Spatial (herkogamy) or temporal (dichogamy) separation of sex organs are mechanisms considered to restrict self-pollination and promote outcrossing. Additionally, avoidance of self-interference is proposed to be the driving force for the evolution of ...

Genome size, morphological and palynological variations, and heterostyly in some species of the genus Linum L. (Linaceae) in Iran [PDF]
Heterostyly is the occurrence of flowers with different sexual organ arrangements in different plants of the same species. This floral polymorphism occurs in four sections of genus Linum.

Primula chungensis is a species with considerable floral and mating-system variation, including distylous (outcrossing), homostylous (selfing) and mixed populations that contain both outcrossing and selfing forms.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Studies on Incompatibility Pollination and Floral Morphological Polymorphism of Carambola (Averrhoa Corambola L) [PDF]
The objectives of this study were to elucidate the physiological basis of selfincompatibility system and the floral morphological polymorphism in carambola (Averrhoa carambola L.). Within 30 minutes after pollination, pollen degradation and hydration

Distyly is a genetically controlled floral dimorphism, characterized by the reciprocal positioning of pin and thrum morphs, a heteromorphic incompatibility system and a balanced morph ratio (isoplethy).

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]
Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Rapid detection of RNase‐based self‐incompatibility in Lysimachia monelli (Primulaceae)
Abstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.
