Development of simplified PAM chlorophyll fluorometer for vegetation condition monitoring

摘要

Environmental issues are getting widespread international attention. The damage to the plant is immeasurable, too. For monitoring the vegetation conditions, a non-destructive, simplified and low-cost chlorophyll fluorometer was developed. Pulse amplification modulation method and control using programmable logic controller has been employed for that purpose. By measuring the fluorescence from spinach leaf, the performance of the system was checked. It was found that the system was provided empirical data to support theory.
