The dark side of the rain: self-pollination setbacks due to water exposure in Pavonia varians Moric (Malvaceae), a species with rain-dependent flowering [PDF]
Acta Botânica Brasílica, 2020 Plants that occur in arid or semi-arid environments may restrict their flowering to the rainy season to ensure water availability for reproductive functions. However, the exposure of flowers to rainfall can compromise their functionality, such as complex

Extent of cross-fertilization in Orobanche cumana Wallr.
Biologia Plantarum, 2013 Sunflower broomrape (Orobanche cumana Wallr.) is considered a self-fertilizing species, but there is no indication as to whether it is strictly self-fertilized or that it presents some extent of cross-fertilization.

THE EVOLUTION OF AUTOGAMY IN SPECIES OF THE MUSTARD GENUSLEAVENWORTHIA [PDF]
Evolution, 1977 In about 80% of all species of hermaphroditic flowering plants the pollen is incapable of germinating on the styles of the flowers that produce it, a condition known as selfincompatibility (Fryxell, 1960). The genetic control is usually simple, one-locus, and multiallelic (Lewis, 1954) although more complex two-locus systems are known (Lundquist, 1975).

Pollination Ecology of Sabatia Campenstris Nutt. (Gentianaceae)
Oklahoma Native Plant Record, 2016 Flower timing studies in June and July (1972) on populations of Sabatia campestris Nutt. show this plant to be allogamous (out crossing) under natural field conditions.

Induction of autogamy by treatment with trypsin in Paramecium Caudatum [PDF]
Journal of Cell Science, 1979 ABSTRACT Firmly united conjugant pairs of P. caudatum were easily separated by treatment with trypsin, 0 · 025–1 · 0 mg/ml in 2 mM phosphate buffer at pH 7 · 2. Cytological observations showed that pairs separated by this means undergo normal meiosis and subsequent prezygotic divisions.

Preventing self-fertilization: Insights from Ziziphus species
Frontiers in Plant Science, 2023 The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.
