Abstract

Soybeans were grown at varying nitrogen levels to produce a range of physiological conditions. The plants were used to identify and define the function of certain of the plant components which contribute to the blue fluorescence band in LIF spectra. Three important compounds were identified. These included reduced nicotinamide adenine dinucleotide phosphate (NADPH), a semiquinone, and xanthophyll. It was shown that all of these compounds participated in photosynthesis
