The article reviewed the data of an old experiment with Potentilla anserina in planting with a density of1, 5 and 9 ind./ m2, conducted in 1996 under natural climatic conditions on stationary sites. The study was conductedin innovative Concept “Polycentric Mmodel of Plant.” Changes in the growth indicators of the polycentric system ofthe plant from June to October were revealed in connection with seasonal changes in the climatic factor. This is thesum of the temperatures and the amount of precipitation between the periods of control observations of the plant. Themost favorable weather conditions for the formation of shoot-formation centers, mineral-nutrition centers and generationcenters as elements of Polycentric Model of Plant are determined. The maximum number of stolons, shoot-formationcenters, mineral-nutrition centers, and generation centers has been determined that can actively function on an area of 4square meters in plantings of different densities.
