Controlled pollinations reveal self-incompatibility and inbreeding depression in the nutritionally important parkland tree, Parkia biglobosa, in Burkina Faso

Journal of Pollination Ecology, 2018
The socioeconomically important fruit tree Parkia biglobosa is becoming less abundant in the West African savannah, possibly due to poor regeneration.

The effect of the limitation of insect pollination period on the fruit set and yield of temperate-zone fruit tree species

International Journal of Horticultural Science, 2000
The duration of effective bee pollination period was limited by caging flowering branches for shorter or longer time in blooming fruit trees in a number of experiments during the past decades.

Studies on self- and cross-pollination of olives under varying temperature conditions

California Agriculture, 1961
Investigations with Ascolano, Manzanillo, and Sevillano olive varieties show that chances of fertilization and fruit set are much greater after cross-pollination than after self-pollination.

The Self-Pollination of Amur Honeysuckle

, 2021
Amur honeysuckle (Lonicera maackii) poses a dire threat to the health of forests throughout the eastern United States. While self-pollination has been identified as an important trait of invasive plant species, this trait is understudied, and Amur honeysuckle is anecdotally described as lacking this characteristic.

The reduction in genetic quality of seeds resulting from self-pollination acts as a pivotal factor limiting the regeneration of the endangered plant Tetracentron sinense Oliv

Global Ecology and Conservation
Tetracentron sinense Oliv., an endangered relict species from the Eocene, primarily relies on self-pollination in nature. However, the impacts of self-pollination on seed quality, seedling viability, and population renewal remain unclear.
