The open photoacoustic cell (OPC) technique is applied to photosynthesis research in leaves, where the leaf is still attached to the plant. It is shown that real in situ and in vivo measurements of photosynthetic activities in leaves can be performed. The dehydration effect after cutting the leaf from the plant was monitored and some qualitative measurements related to photosynthetic activities are reported in order to show the usefulness of this technique in this field.
