Graft chimera
A graft chimera is a term from biology that describes a plant that has arisen from two genetically different original species. A graft chimera arises at / from the contact point between the base and the noble rice and has properties of the two original types.
This is not actually a hybrid , since a graft chimera contains different cells with the respective genetic information of the two starting species, while the genetic information is fused together in the cells of a hybrid.
A graft is in contrast from genetically distinct backing and a scion - stretching up to the contact at the site of grafting not mix.
designation
As a formula
The names of the output species are listed in alphabetical order and connected by the plus sign (+): Crataegus + Mespilus
As a name
If the output species belong to different genera , a name can be assigned which is composed of the names of the two genera. Example: + Crataegomespilus is the name of a graft chimera (from representatives of the genera Crataegus and Mespilus ), which can also be written as Crataegus + Mespilus .
If the parent species belong to the same genus, the graft chimera can be given a cultivar name - examples: Syringa 'Correlata' is a graft chimera of Syringa vulgaris (common lilac ) and Syringa × chinensis (a hybrid between S. vulgaris and S. laciniata ). Aesculus + dallimorei is a graft chimera from A. hippocastanum and A. flava . The "+" sign can be dispensed with, since both output types belong to the same family .
A graft chimera must not be named as a species , as it genetically consists of two species.
