Abstract: The invention relates to the plant physiology and may be used in the agriculture for the plant physiological state assessment and their adaptation to the medium unfavourable conditions. The purpose of the invention consists in increasing the diagnostics precision and decreasing the labour input. For realization of the process on the plants are attached detectors by means of which is metered the transpiration rate of the water per unit of the leaf surface (E) and the temperature difference between the leaves and the environment by which is determined the temperature difference between the plant and the environment as medium for every leaf, after that are determined the heat losses in power units by the relation Q=LE+αΔT, wherein L is the evaporation specific heat; α constitutes the heat transfer coefficient; ΔT is the average difference between the leaves temperature and the environment one. After measuring the stationary level of the heat losses on the plants are acting on with the stress factor that leads to the “splashing” of the heat losses and subsequent stabilization of these assessments at a new stationary level. So, the determination of the organization heat losses as loss sums in the transpiration process and heat transfer allows by the stationary level of the heat losses to assess the physiological state of the organism in the given environment conditions and by the heat losses dynamics allows to assess the adoption to the growth conditions change.
