Speciation Under Self-Pollination
1999Self-pollination introduces automatically reproductive isolation both between lines (within a species) and between species. It is argued that the reproductive isolation barrier caused by this breeding system affects considerably the mode of speciation in autogamous plants: it frequently substitutes for geographic separation, and facilitates the build ...

Facultative Self-pollination in Island Irises
American Midland Naturalist, 1997-Blue flag (Irzs versicolor) is an insect-pollinated clonal plant found in wet habitats throughout northeastern North America. Our study of an isolated population on Kent Island, New Brunswick, showed that blue flag was self-compatible. Moreover, we found no evidence of inbreeding depression.

Self-Pollination Effects on Seed and Seedling Traits in Noble Fir
Forestry sciences, 1976Noble fir trees yielded on the average 69 percent as many sound seed after self- as after cross-pollination. Seed weight, germination percent, and seedling survival during 3 years were not affected by type of pollen.

Pollination of self-fertile sweet cherry
Journal of Horticultural Science, 1979SummaryPrunus avium L. ‘Stella’ was shown to be fully self-fertile but bee pollination improved final fruit set and number of fruits harvested, compared to pollination by wind and gravity. Pollination of individual flowers by their own pollen was at least six times more frequent than by pollen from more distant flowers.

Ecology, 2006
Reproductive assurance is often invoked as an explanation for the evolution of self-fertilization in plants. However, key aspects of this hypothesis have received little empirical support. In this study, I use geographic surveys of pollinator communities along with functional studies of floral trait variation to examine the role of pollination ecology ...

Botany: a new self-pollination mechanism.
Nature, 2004Pollen grains from most flowering plants are transported by wind or animals and deposited on the receptive surface of the stigma of a different individual, but self-pollination is also common. We have discovered a new process for self-pollination in the laterally orientated flowers of a Chinese herb, in which a film of pollen is transported from the ...
