Abstract
The paper presents the simulation of growth processes patterns for the most important morphometric parameters of the Echinacea pallida in pregeneration period of the ontogenesis. The patterns were created on the basis of the data collected from the industrial crops during the industrial Echinacea pallida cultivation. The dynamics of increase aboveground phytomass, and the number of leaves of Echinacea pallida, obeys the sigmoid function and may well be described by the Hill equation. The reasons for the mathematical similarity of the processes for the phytomass and the number of leaves are considered, which indicates synchronous processes of accumulation of the phytomass and an increase in the leaf number. The dynamics of the biomass of Echinacea during the year can be represented as a composition of two components. Spring and is a normal component and reflects the general laws of change of biomass of which point to the existence of this particular species in a particular ecological and geographical space. Specificity intraseasonal components is the presence of deviations from the general trend changes phytomass, which are explained using echinacea leaf shape index and temperature variations observed from the general trend of the changes in the season. It is shown that temperature fluctuations are a factor that influences the production process of Echinacea. Proved that temperature fluctuations have a situational influence on plant growth. Provided evidence that the information value of the leaf shape index is the result of the memory of the plant processes that it occurred during ontogeny. The morphological status of the plant determines the potential for further development, depending on the climatic characteristics at a given time. Phytomass dynamics is determined by fluctuations of climatic factors in the particular period and the growth processes characteristic of flow in the early stages of ontogenesis.
