Model for expressing leaf photosynthesis in terms of weather variables*

Part of a thesis submitted to the University of Wales, Aberystwyth in partial fulfilment of the Ph.D. degree.

Abstract

A theoretical mathematical model for describing photosynthesis in individual leaves in terms of weather variables is proposed. The model utilizes a series of efficiency parameters, each of Which reflect the fraction of potential photosynthetic rate permitted by the different environmental elements. These parameters are useful to breeders and agriculturalists involved with increasing the efficiency of the utilization of solar energy by plants. The significance and use of the parameters is discussed.

UITTREKSEL

‘n Teoretiese wiskundige model vir die beskrywing van fotosintese van enkele blare in terme van die weerselemente word voorgestel. Die model gebruik verskeie doeltreffendheidsfaktore elk waarvan die breuk van die potensiële fotosintetiese tempo, wat weersomstandighede toelaat, weerspieël. Die faktore is waardevol vir telers en landbouers wat die doeltreffendheid waarmee plante sonstraling benut, wil verhoog. Die betekenis en gebruik van die parameters is bespreek.
