Spectral composition of light and plant productivity.
Among other problems the Institute of Biophysics is working on the development of physiological and fundamental aspects of intensive light cultivation of higher plants.  These technologies can be used in life support systems for stationary space station such as a Lunar base, a planetary base or a large orbital station.  The source of energy may be the Sun or a nuclear reactor.  In certain conditions, such sources of energy allow the use of a very broad range of irradiance of plants, in particular in the light energy range up to 2-3 times the solar energy (up to 100-1200 W/m2 PAR).  Our Institute was the first to show that under such a high irradiance, some plants (radish, wheat, for example) can actively photosynthesize and exhibit high productivity on a sowing area basis.  These results were later confirmed in the laboratory of Prof. Salisbury (USA).
