Abstract
In this paper the use of the so-called open photoacoustic cell (OPC) detector technique for in vivo and in situ measurements is described. Spectroscopic and photosynthetic properties in undetached maize leaves are measured. Photosynthetic oxygen evolution detected by OPC apparatus is estimated using a Clark-type oxygen electrode sensor.
