Temperature dependence of plant and crop process

Abstract

The quantitative effects of temperature on plant and crop processes are discussed and related to the underlying theory, by means of a critical and expository essay which aims to provide a conceptual basis for the consideration of these problems. The topics considered include the Arrhenius equation and Q10; the collision and transition-state theories of the rate constant; models with a temperature optimum; models without a temperature optimum; phase changes; diffusion, viscosity and translocation; hybrid systems (biochemistry plus transport); photosynsthesis; respiration; and development with the day-degree hypothesis. © 1985 Annals of Botany Company.
