Introduction Mitogenetic effect in Yeast cell Supe from Soya seeds: Spectral distribution and  temperature dependence Conclusions References

Page 4 of 5

It has been confirmed the mitogenetic effect both in solid and in liquid culture and it has been shown that the effect is correlated in time to the maximum of the yeast growing rate and of ultraweak photon emission. Moreover it has been pointed that attention must be given to the experimental conditions, which must be analyzed and compared carefully in order to reproduce the experiments. The controversial results in this field could be attributed in fact to the different experimental conditions.

As it regards the SUPE from soya seeds, it has been demonstrated that the photon emission from germinating seeds depends strongly on time, the time dependence being different according to the physiological state of the seeds.

Moreover the photon spectrum has two relevant contributions in the UV and red extremes, being zero in the visible range and the different spectral components show different time dependences, which change with the seeds physiological state; the high yield of the UV component at the starting of germination could be the experimental evidence of the mitogenetic radiation, expected to be in the same spectral region.

The correlation of the emission of biophotons with the process of germination in live seeds has been demonstrated; in fact the process of germination and that of emission show the same dependence on temperature, giving origin to the same activation energy, while the activation energy relative to the emission and imbibition is different.

As a consequence of the above considerations and measurements it is possible to state that the ultraweak luminescence induces biological effects and thereafter has a regulatory role in the metabolism of the cell cycle.

The correlations evidenced, as well as the correlation between bioelectrical activity in seeds and ultraweak emissions found from other researchers [5], make one hypothesize an eventual not necessarily biochemical approach to the understanding of the ultraweak emission and of the behaviour of the biological systems.

Even if the specific emitters and the concrete mechanism of the biophotons are not yet known, the results of the measurements shown consolidate the fact that ultraweak emission is a phenomenon widespread in nature and is connected to the fundamental processes of life.

In order to better understand the mechanism of emission it will be necessary to explore the biological processes occurring during the growth in order to have a better knowledge of the time dependence of other biological parameters; is also necessary to better characterize the time dependence of the spectral emission, which could add more information about the origin and the role that ultraweak photon emission has in biological systems.
