Abstract

The different photosynthetic and morphological characteristics of C₃ and C₄ plants may lead to distinct physiological responses of C₃ and C₄ crops to stress factors. These responses are strongly correlated with the red edge of these plants, the s-shaped curve in the 680-800nm region of their reflectance spectra. We performed controlled in silico experiments to investigate the patterns of the red edge displacements resulting from C₃ and C₄ specimens subjected to the same stress conditions. Our findings indicate these patterns need to be taken into account in the development of effective monitoring procedures for C₃ and C₄ crops.
