A dynamic model for photosynthesis

Abstract

A dynamic mathematical model of the effect of radiant flux density and CO2 concentration on the rate of photosynthesis is proposed. An appropriate dynamic experimental method for ecological studies of this subject is described. The methodology permits the analysis of numerous problems, including the effect of changes in CO2 concentration on photosynthesis and the effectiveness of energy conversion by a leaf of a plant in different environmental conditions.The dynamic model for photosynthesis is composed of two separate interacting non-linear parts; one describes the dynamics of the complex set of light reactions, and the other describes the dark reactions. The model explains the dynamics of leaf photosynthesis in a closed circuit flow system, and also explains the expressions for the equilibrium states of photosynthetic rate widely used in the literature. © 1982 Annals of Botany Company.
