摘要：

A portable field apparatus for the measurement of photosynthesis is described. Short pulses (20 s) of air containing 14CO2 are applied to circular leaf areas of 1 cm2, enclosed in a transparent miniature chamber; the radioactivity of the leaf areas is measured by liquid scintillation, using a new in-vial wet combustion technique. Typical daily courses of photosynthesis in maize and cotton are presented. © 1969 Oxford University Press.
