Overview
Plant Photosynthesis Tester is an experimental instrument used to detect the photosynthesis of living leaves of plants in artificial climate chambers, greenhouses, greenhouses, and fields. The content of the measurement includes air CO2 concentration, environmental temperature and humidity, leaf temperature and humidity, leaf surface temperature, atmospheric pressure, photosynthetically active radiation (PAR), leaf photosynthetic rate (Pn), stomatal conductance (Gs), leaf transpiration rate (Tr), intercellular CO2 concentration (Ci), water use efficiency (WUE), respiration rate (Rd), transpiration ratio (TR), and a total of 15 parameters. It can be used for scientific research on plant growth physiology, photosynthetic physiology, stress physiology, etc. The plant photosynthesis tester is suitable for agricultural research, teaching, horticulture, grassland, forestry, and other fields. And a wider range of fields.
