RESUMO

An open-cell photoacoustic (OPC) spectroscopic technique is described which can assess genetically rooted differences in the response of live specimens of corn (Zea Mays L.) to the toxic action of aluminum. It is shown that this alternative signal-to-noise enhanced photoacoustic configuration allows us to obtain both absorption and transmission spectra with minimal requirements of experimental arrangement and cell machining. This process also permits "in vivo" experiments and the measurement of optical and thermal properties of plant leaves.
