Abstract
Invasive weeds are characterized by high phenotypic plasticity, which allows them to adapt to new climatic conditions due to variable phenotypes that have arisen in the historical time scale under the control of natural selection. Colonization of such plants takes place locally in accessible anthropogenic cenoses. In the South of Russia the most typical invasive plant isAmbrosia artemosiifoliaL. We We examined the discrete variation by vegetative feature — shoot length according to 12 genotypes of ragweed in agrocenoses of Krasnodar Krai.
Highlights
In different environments, one genotype can reflect different phenotypes
The periods of plants development can be flexible, and many phenotypic reactions to environmental stress factors can be the result of a decrease in shoot length [12, 13]
Vegetative traits, such as shoot length, in ragweed vary depending on the type of agrocenosis and its genotype
Summary
This phenomenon is known as phenotypic plasticity [1]. Ragweed is a classic invasive weed plant that populates anthropogenic landscapes due to its rapid adaptation to environmental factors. This process proceeds in the form of incoherent evolution due to epigenetic system rearrangements reinforced and fixed by natural selection for several generations. Such ecological plasticity allows ragweed, and many other invasive species to invade a heterogeneous habitat [2, 3]
