Abstract:
Background: Research objective - to calculate energy of oscillation of biological time of plant in ontogenesis under the influence of weather environment. At the same time, the simplest model of system for the first calculation is taken. Methods and Findings: Biological time is represented in the form of the dependence on photosynthesis and respiration processes of the whole plant organism via ??2 exchange. Two-dimensional temporal space is implemented naturally. Consideration is given to the issue of biological time oscillations during plant ontogenesis. It is believed that lowering the air temperature from the optimum level down to the actual temperature would deviate the biological temporal vector from the physical time axis. The time change is deemed to be an integral of the scalar product of the biological temporal vector with the physical time axis. The flow rate of biological time is determined by the rate of CO2 exchange for the whole plant depending on the state of environmental factors (photosynthetic active radiation (PAR), air temperature, and productive soil moisture). Oscillations of the newly obtained normalized logistic curve of plant growth are assigned to those of the whole plant biological time. Conclusions: The potential and kinetic oscillation energy of biological time of the whole sunflower plant during ontogenesis is calculated subject to the condition of environmental factors. The plant organism is considered as a simplified system or a conservative system.
