Keywords: Mathematical model, Noni, Photosynthetic pigments, Temperature, Electron transport chain


This study aimed to develop a mathematical model to understand the acclimatization potential of photosynthetic electron transport in both tissue of leaf and developing fruit, exposed to contrasting temperatures. This dynamic mathematical model covers photosynthetic apparatus that contain variety of pigments, photo-systems, electron carriers, and final electron acceptor complex, ferredoxin. The proposed model explained the variations of photosynthetic pigments pool viz., Chla, Chlb, total Chlorophyll, and Carotenoids; OJIP transients i.e., Fv/Fo, Fv/Fm, φ(Eo), Plabs and Pltotal concerning varied temperature in a perfect way with r =  ~ 1 and S =  ~ 0 for leaves as well as developing fruits. Since the correlation coefficients for the parameters are unity, perfect validity of the hypothesis and developed model. The developed model could be quite useful for accounting total associated physiological responses and for determining optimum temperature requirements for the healthy performance of plants. This model will be used to develop strategies for better growth and development of Noni plants in the current scenario of global climate change.
