Co2 Exchange Rate

It is very important for researching the growth and cultivation of plants that real-time monitoring of photosynthetic physiology & environmental parameters and analysis of relationship between these parameters. In this paper, an indoor cultivated Michelia alba monitoring system was built, which could continuously monitor leaf's CO2 exchange rate, transpiration rate, air temperature and humidity, soil moisture, photosynthetically active radiation and other parameters in real time, and could also analyze the relationship between the photosynthetic physiological parameters and environmental parameters. The results show that the diurnal variation of indoor cultivated Michelia alba leaf's CO2 exchange rate presents a bimodal pattern, which shows a midday depression. The diurnal variation of photosynthetically active radiation presents a single pattern. The diurnal variation of air humidity presents a “ S ” pattern, but the overall variation is little. The environmental factors that influenced the Michelia alba photosynthetic physiological characteristics most greatly are the photosynthetically active radiation and temperature.
