Respiration of Leaves During Photosynthesis I. Estimates from an Electrical Analogue

Abstract

A new analogue for the gas exchange of leaves takes account of respiratory CO ?. During light. saturated photosynthesis, the rate of respiratory CO2 production by some dicotyledons was at least double that occurring in darkness. That this was apparently not so for three grasses, two tropical and one temperate, may be explained morphologically as well as biochemically.
