Reproductive biology of the biofuel plant Jatropha curcas in its center of origin [PDF]
PeerJ, 2016 In this work, we studied the main characteristics of flowering, reproductive system and diversity of pollinators for the biofuel plant Jatropha curcas (L.) in a site of tropical southeastern Mexico, within its center of origin. The plants were monoecious

Pistillate flowers experience more pollen limitation and less geitonogamy than perfect flowers in a gynomonoecious herb [PDF]
New Phytologist, 2013 Summary Gynomonoecy, a sexual system in which plants have both pistillate (female) flowers and perfect (hermaphroditic) flowers, occurs in at least 15 families, but the differential reproductive strategies of the two flower morphs within one individual remain unclear.

BMC Plant Biology, 2021 Background Most orchid species have been shown to be severely pollination limited, and the factors affecting reproductive success have been widely studied. However, the factors determining the reproductive success vary from species to species.

The influence of pollinators on the maintenance of mixed mating in a population of the blue columbine, Aquilegia coerulea (Ranunculaceae) [PDF]
Pollination ecology may play an important role in the maintenance of selfing in populations of self-compatible hermaphroditic plants where both selfing and outcrossing occur (mixed mating).

Journal of Threatened Taxa, 2016 Pavetta indica is a massive bloomer for a brief period in May. The flowers are hermaphroditic, strikingly protandrous, self and cross-compatible, nectariferous and psychophilous. They possess secondary pollen presentation mechanism as a device to avoid

Effects of crossing distance on components of fitness in two rare rock plants
Plant Biology, EarlyView.Crossing experiments between populations of the rare rock species Saxifraga rosacea ssp. rosacea (8×) and S. rosacea ssp. sponhemica (6×) resulted in heterosis for some traits and outbreeding depression for others. Crossing the two subspecies resulted in sterile hybrids indicating that mixing populations of rare species is not always beneficial ...

, 2001 Geitonogamy (the pollination between flowers on the same plant) has important implications for sex-allocation theory, the evolution of dioecy and other issues in evolutionary biology. Internal geitonogamy is a unique self-pollination system that occurs

Fitness Effects of Somatic Mutations Accumulating during Vegetative Growth [PDF]
, 2022 The unique life form of plants promotes the accumulation of somatic mutations that can be passed to offspring in the next generation, because the same meristem cells responsible for vegetative growth also generate gametes for sexual reproduction. However,

Annals of Applied Biology, Volume 189, Issue 3, November 2026.This study demonstrates that Sesamum indicum L. combines autonomous self‐pollination and insect‐mediated pollination under tropical field conditions. Autonomous self‐pollination provides reproductive assurance, whereas insect pollination increases grain yield by 28.6%, corresponding to a pollinator dependence of 22%.
