self-fertilisation dans la sélection bibliographique suivante. Des livres en rapport avec

1
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 ...
Sandra E. Shumway, Jay G.J. Parsons, 2011

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 ...
J. L. Chapman, M. J. Reiss, 1999
6
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 ...
Vernonica E. Franklin-Tong, 2008

Gene Flow from GM Plants
Seed production from crosses between male sterile and pollen-producin g lines
Self-fertilisation, low frequency of outcrossing Pollen (wind dispersal) and seeds
Pollen (wind) and seeds Pollen (wind) and seeds Pollen (insects) and seeds ...
Guy M. Poppy, Michael J. Wilkinson, 2008
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 ...
9
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 ...
Alfred Russel Wallace, 2007

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
...
