Self pollination in peach

open access: yesInternational Journal of Horticultural Science, 1999
The peach is though considered to be a self fertile fruit species, also some self sterile and male sterile varieties have been registered. The latter type seems to be frequently met in Asian varieties, whereas in the USA and Europe, J. H.

Floral mechanisms promote pollination success and reduce the incidence of self‐pollination in a fly‐pollinated self‐incompatible orchid [PDF]

open access: yesEcology and Evolution
Among flowering plants, self‐incompatibility is considered the most efficient system for avoiding self‐fertilization. However, many self‐incompatible plants have also evolved floral mechanisms to reduce sexual conflict.

Wind-Dragged Corolla Enhances Self-Pollination: A New Mechanism of Delayed Self-Pollination [PDF]

open access: yesAnnals of Botany, 2007
Delayed self-pollination is a mechanism that allows animal-pollinated plants to outcross while ensuring seed production in the absence of pollinators. This study aims to explore a new mechanism of delayed self-pollination facilitated by wind-driven corolla abscission in Incarvillea sinensis var.

Yam (Dioscorea rotundata Poir.) Displays Prezygotic and Postzygotic Barriers to Prevent Autogamy in Monoecious Cultivars

open access: yesAgronomy, 2022
Cultivated yam (D. rotundata) is a staple tuber crop in West Africa whose sexual reproduction control remains largely unknown despite its importance for plant breeding programs. In this paper, we compared self-pollination, intracultivar cross-pollination
