Does autogamy contribute to invasion in Lilium formosanum?
South African Journal of Botany, 2008 The Taiwanese geophyte Lilium formosanum is invasive in the eastern parts of South Africa. Although it is capable of autogamy, a pollinator, the hawkmoth Agrius convolvuli, is present. Reproduction may therefore take place both by self- and cross-fertilisation. The relative importance of these modes of pollination for seed production is evaluated using

Evaluating Self-Pollination Methods: Their Impact on Nut Set and Nutlet Abscission in Macadamia [PDF]
PlantsNut set is an important determinant of yield and plays a pivotal role in orchard profitability. The complex process of nut setting is governed by numerous factors, with pollination being a critical mechanism.

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa [PDF]
American Journal of Botany, Volume 113, Issue 6, June 2026.Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

Exchanging Genes Within a City: Analysis of Pollen Flow Patterns in a Narrow Endemic Plant Species Threatened by Urbanisation [PDF]
Ecology and Evolution, Volume 16, Issue 4, April 2026.Anthropogenic habitat fragmentation can severely disrupt gene flow in endemic plants that depend on species‐specific native pollinators with limited dispersal ability. Using paternity analysis across fragmented and continuous populations, we found that pollen flow was maintained in intact bushland but was completely absent between fragments separated ...

Identification of self-incompatibility in macadamia (Macadamia SPP.) using field-bagging and fluorescence microscopy [PDF]
Frontiers in Plant ScienceSelf-incompatibility (SI) significantly reduces crop yield, often far below its genetic potential. Developing self-compatible varieties is the most effective strategy for overcoming SI in crops.

Floral and pollination biology of dragon fruit reveals strategies for enhancing productivity through pollination management and reproductive window extension [PDF]
Scientific ReportsDragon fruit (Selenicereus undatus (Haw.) D.R. Hunt) is emerging as a high-value crop globally. However, its reproductive biology remains poorly characterized, with conflicting reports ranging from strict self-incompatibility (allogamy) to self ...

Artifact Autogamy in Sunflower1
Crop Science, 1980 Prior to the development of autogamous cultivars, cross‐pollination was required for high yields of sunflower (Helianthus annuus L.). This research was undertaken to identify highly autogamous cultivars and to compare cloth and mesh bags in measuring autogamy for yield, achene weight, and achene oil percentage.

, 1990 The ciliate Paramecium tetraurelia exhibits two major developmental pathways - the vegetative cell cycle and the sexual pathway. The latter manifests itself in two forms -autogamy (self- fertilization) and conjugation (cross-fertilization) between cells ...
