Real-Time Monitoring of Carbon Monoxide Production and Utilization by Plants with Tunable Diode Laser
CO in the microcosm of some plants was studied using a carbon monoxide analyzer based on tunable diode lasers. The designed analyzer has a high sensitivity (at 5 ppb) and close to 100 percent selectivity to water vapours and CO2, allowing for real-time CO monitoring in a plant microcosm. One of the goals of the research was to show that using spectral gas analysis based on tunable diode laser spectroscopy, it was possible to examine CO generation and usage by plants. CO production and release into the environment were measured in our in-vitro experiment. early stages of plant development were discovered in the atmosphere (stage of germination and growth of seedlings wheat, cucumbers and colza). When examining the CO levels in the microcosm of the produced plants, a high CO absorption from the surrounding air was detected.
