Stages of introduction development as a scientific activity

The concept of “Introduction” is ambiguous. It is associated with a long period of human introduction activity. There are six stages of introduction development: from 8000 years BC (intuitive stage) to the present. For a long time, the practical development of the introduction was significantly ahead of the theoretical one. In 1972, the adopted definition of introduction, as a purposeful human activity for introduction into culture, reflected the applied direction in introduction. In the XXI century, we observe a culminating development of the theoretical direction -introduction is formed as a science. The objects of introduction research are both plants and introduction points. Introduction methods are extensive. The specific language is being formed. New terms and concepts (for example, evaluation of the success of introduction), graphic and iconic images are proposed. Introduction, as a science, is based on fundamental achievements of ecology, botany, genetics. Introduction studies are the basis of breeding, agronomy, floriculture. The authors follow to the following definition of introduction: “It is a science that studies the processes occurring in plants and their offspring as a result of the transfer of plants to new habitats”. In practical terms, introduction is the transfer of plants to new habitats, in theory - the study of the processes of acclimatization and adaptation.
