The Effects of Cross and
Self Fertilisation in the Vegetable ...
In this book Darwin provides experimental evidence for a hypothesis stated in his famed book of 1859, Origin of Species, that "... in none [i.e. plant] [...]can self-fertilisation go on for perpetuity" (Origin p101).

Longman A-Level Biology: Growth, Development and Reproduction
2 There are two types of fertilisation: (a) Self-fertilisation Self-pollination leads to
self-fertilisation. Self-fertilisation involves the fusion of a male gamete with a
female gamete from the same individual. Self-fertilisation is a form of inbreeding.
5 INBREEDING Most cirripedes are hermaphrodites (Darwin 1854, Charnov, this
volume) and are potentially capable of self-fertilisation. Barnes & Crisp (1956)
looked for nauplii in isolated individual barnacles. They showed that Chthamalus
...

Scallops: Biology, Ecology and Aquaculture: Biology, Ecology ...
Several scallop species such as P. maximus, A. irradians and A. ventricosus (=
circularis) are hermaphroditic and, in hatchery situations, some self-fertilisation is
the rule rather than the exception (Beaumont et al. 1982; Wilbur and Gaffney ...

Ecology: Principles and Applications
In fact they often have mechanisms which prevent self-fertilisation occurring,
although under certain circumstances this may happen. Some of the mechanisms
found in angiosperm plants which promote outcrossing by making self-
fertilisation ...

Self-Incompatibility in Flowering Plants: Evolution, ...
Obviously, the utility of a breakdown of SI with floral or reproductive age as a
mechanism to provide reproductive assurance is enhanced when it is coupled
with additional floral mechanisms that enable autogamous self-fertilisation in old
but ...

A common mechanism for self-fertilisation is the dehiscence of anthers before the
florets open and the stigmas are exserted (Richards, 1986). This mechanism
achieves a balance between self- and cross-fertilisation and also between
genetic ...

Darwinism: An Exposition of the Theory of Natural Selection ...
Yet more extraordinary is it to find numerous cases in which the special
arrangements for cross-fertilisation appear to have been a failure, since they
have either been supplemented by special means for self-fertilisation, or have
reverted back ...

On the Origin of Species
When the stamens of a flower suddenly spring towards the pistil, or slowly move
one after the other towards it, the contrivance seems adapted solely to ensure
self-fertilisation; and no doubt it is useful for this end: but the agency of insects is

Precious pollinators
Pollination can occur between plants when pollen is carried by the wind or by insects such as the honeybee, or within the same plant (self-fertilisation). «Trinidad Guardian, जुलै 15»
