摘要：
An optical method for assessing the functional state of plants, including measuring the optical parameters of chlorophyll-containing tissues, characterized in that the light scattering dynamics of photosynthetic plant tissue is recorded during exposure to the blue spectral region (in the region of the first absorption peak of chlorophyll 460-480 nm) with a power density of 150-400 W / mV for 20-40 seconds, then the monochromatic probing radiation of the red region of the spectrum is activated (in the zone of the second absorption maximum I chlorophyll 650-660 nm) with a power density of 2500-6000 W / m, and for the next 30-120 seconds they continue to record the dynamics of light scattering of the same tissue site； photosynthetic activity and resistance to photodestruction are judged by the magnitude and sign of the indicators α and β, which are calculated by the formulas: It and It, where α - the rate of change of light scattering intensity during exposure to optical blue region of the spectrum； I - the average light scattering intensity in the first 1-3 seconds of exposure to optical blue region of the spectrum； β - the rate of change of light scattering intensity during exposure to optical radiation in the red region of the spectrum； I is the average light scattering intensity in the first 1-3 seconds of exposure to optical radiation in the red region of the spectrum； t is the current time； in this case, the higher the value of the moduli of these indicators with a negative sign, the higher the photosynthetic activity and resistance to photodegradation, and the higher the value of the modules of the indicators α and β with a positive sign, the weaker the photosynthetic activity and resistance to photodegradation.Оптический способ оценки функционального состояния растений, включающий измерение оптических параметров хлорофиллсодержащих тканей, отличающийся тем, что регистрируют динамику светорассеяния фотосинтезирующей растительной ткани в процессе засветки мон
