"WebPhotosynthesis systems use infrared gas analyzers (IRGAS) for measuring photosynthesis. CO 2 concentration changes in leaf chambers are measured to provide carbon assimilation values for leaves or whole plants. Research has shown that the rate of photosynthesis is directly related to the amount of carbon assimilated by the plant. " - Measuring photosynthesis
