Ultraweak luminescence of theCharaceaeplants under the circumstances of cyclical changes in temperatureThe study sought to measure ultraweak chemiluminescence (UWL) ofNitellopsis Obtusaplants with regards to temperature changes within the range from 4°C to 38°C. The temperature changes were being executed in reversible cycles. The variations of UWL intensity with temperature had an exponential character. In case when temperature was changed rapidly by 5°C every 20 min or fluently with rate of 0.17 °C/min we observed a temperature hysteresis loop in the first cycles and the loop character disappeared in the second cycles. When the temperature was being changed fluently but faster (1.3 °C/min) after 3 cycles (about 2 hours) the curves no longer manifested the loop character. This phenomenon can point that the plants adapted themselves to the temperature changes. We also observed a stimulation of UWL made in successful cycles. Our spectral experiments showed that the UWL may consist mainly of emission of the singlet oxygen sigma (762 nm) and induced emission of chlorophyll.

Abstract Ultraweak Photoemission, Biological Systems, Cell Communication Measurements on untreated yeast cells, potato-and cucumber seedlings have confirmed the existence of photon emission from biological systems known as “ultraweak luminescence”. The intensity is of the order of 102 counts per second, and the spectral distribution shows a maximum near 550 nm. The dependence of the photon emission on certain chemicals has been investigated. Some chemicals, as for instance acetone, intensify the photon emission from cucumber seedlings without essential change of the spectral distribution. On the other hand, NaCl leads to a shift to the red region of the spectrum. The treatment of EAT-cells by 4-Hydroperoxycyclofosfamide involves a nonlinear enhancement of the intensity with increasing concentration. There are some indications that collective interactions of the system are more appropriate than simple chemiluminescence reactions.
