Managed honeybees decrease pollination limitation in self-compatible but not in self-incompatible crops

open access: yesProceedings of the Royal Society B, 2022
Modern agriculture is becoming increasingly pollinator-dependent. However, the global stock of domesticated honeybees is growing at a slower rate than its demand, while wild bees are declining worldwide. This uneven scenario of high pollinator demand and

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.
