Genet

from Wikipedia, the free encyclopedia
Genet from Iris germanica

A genet (from Greek γενεά geneá , German 'descent' ) is a term used in botany to describe a collective of plants (or fungi ) that are or were connected underground, for example via a rhizome (or mycelium ). The plants seem to be independent, but actually originated through vegetative reproduction and form a clone (cf. English clonal colony as a synonym for genet ).

As Ramet is called a "Klongeschwister", ie the smallest viable unit of Genet. The terms Genet and Ramet are to be understood in the context of each other. All ramets of the same origin form the entirety of a clone.

According to this, a strawberry mother plant with its runners is a gene , all of its offshoots are ramets and together form a clone. The same is true, for example, of a vegetable or tulip onion and its descendants, which are the result of the daughter onions .

These terms are used particularly in current research in order to be able to clearly characterize vegetatively developed individuals and their precursors. For example, the trees of an entire forest can be ramets of a single gene, such as Pando . A large part of the individuals in grass stocks can also be based on vegetative reproduction ( dividing formation ).
