The role that the spontaneous ultraweak photon emission (SUPE) plays
in the living systems is not yet clear. This is due probably to the difficulty
of the experimental observations that, since they refer to living systems,
are not so reproducible to give clear and sure indications and interpretations
of the results. For this reason it is very important well define the biological
systems, the biological conditions, the experimental conditions, and so
on. The correct analysis of the experimental conditions is the basis for
the better understanding of the SUPE.
Two experimental lines on SUPE has been developped in the Institute:
the first deals with the photon emission from the yeast cell and the biological
effects of such radiation; the second line regards the emission during
the germination of the seeds.
The experiment on the emission from the yeast cells and the mitogenetic
effect is probably the one that has given the most controversial results.
In fact the number of experiments that evidenced the effect, mainly in
Eastern country, is roughly balanced by the number of "no effect" results
in Western countries. The results in Catania have evidenced the effect,
even if a more reliability should be required.
The experiment on the photon emission from seeds and its correlation
with the germination activity has been carried out for soya seeds, since
this biological system has shown a high degree of reproducibility of the
measure of the biological parameters and SUPE. In this experiment, moreover,
it has been evidenced, during the growth of the seeds, the existence of
the UV radiation that should play an important role in cell division.
