WAS BEDEUTET NUCELLAR AUF ENGLISCH
Samenanlage
Ovule bedeutet "kleines Ei". In Samenpflanzen ist die Ovule die Struktur, die die weiblichen Fortpflanzungszellen hervorbringt und enthält. Es besteht aus drei Teilen: Das Integument bildet seine äußere Schicht, den Nucellus und weiblichen Gametophyten in seiner Mitte. Die weibliche Gametophyte, die speziell als "Megagametophyt" bezeichnet wird, heißt auch Embryosack in Angiospermen. Der Megagametophyt produziert eine Eizelle zum Zweck der Befruchtung. Nach der Befruchtung entwickelt sich die Eizelle zu einem Samen.

nucellar in der folgenden bibliographischen Auswahl. Bücher, die mit
nucellar im Zusammenhang stehen und kurze Auszüge derselben, um seinen Gebrauch in der Literatur kontextbezogen darzustellen.
1
Citrus Genetics, Breeding and Biotechnology
Nucellar embryony allows citrus rootstock breeders to produce F1 hybrids that
are highly heterozygous, but produce seedlings that are genetically uniform and
identical to the mother tree. If nucellar embryony were not present, citrus
breeders ...

In Vitro Culture of Higher Plants
In Vitro Culture of Higher Plants presents an up-to-date and wide-ranging account of the techniques and applications, and has primarily been written in response to practical problems.

Nucellar and Integumentary Embryony During integumentary or nucellar
embryony (also called adventive embryony), asexual embryos are formed from
inner integumentary or nucellar cells that are differentiating in tissues external to
the ...

Citrus Botany and the Importance of Nucellar Embryony Not all scientists agree
on the number of citrus species, but scientists do concur that their botany is
complicated. In many kinds of plants, species within a genus will not interbreed,

The mechanisms which specify only some nucellar cells to form nucellar embryo
initial cells are unknown as is the time during ovule development that nucellar
embryo initial cells are first specified. The egg cell and polar nuclei in the sexual

chalazal zone) and continues into the nucellar projection up to the endospermal

In addition to the well known examples of Mangifera and Citrus genera, nucellar
polyembryony is observed in some species under the genera Opuntia and
Trillium. Species variation with respect to manifestation of polyembryony is noted
in ...

Fruit Breeding, Tree and Tropical Fruits
This behavior occurs in both sexual and nucellar seedlings but it can be most
clearly demonstrated in nucellar progeny, where genetic recombination is not a
factor. Thorniness is especially prominent. On trees of most old budded cultivars,
