Аннотация: The effects of potassium halides KCl, KBr and KI on NADH:FMN-oxidoreductase-luciferase bioluminescent coupled enzyme system were studied. The influence of salt additions on bioluminescence intensity and bioluminescence light yield was investigated. The inhibition and activation parameters of the salts were calculated using their dependencies on concentration of the salts. The correlation between the inhibition of bioluminescence intensity and the halide mass was demonstrated: the inhibiting ability of the salts increases with the increase of atomic weight of the anions. The inhibition parameters increase and the activation parameters decrease, accordingly. (C) 2002 Elsevier Science B.V. All rights reserved.

Conceptual approach to selecting radiation spectrum of lamps for plant cultivation in artificial conditions / A. A. Tikhomirov, S. A. Ushakova, V. N. Shikhov, E. S. Shklavtsova // Light Eng. - 2019. - Vol. 27, Is. Special Issue. - P24-39 . - ISSN 0236-2945

Аннотация: Based on own and literature data, the review of existing approaches to justification of concepts of selecting contemporary light sources for plant cultivation in greenhouse conditions is presented. The work covers comparative experimental data on productivity of lettuce leaves formed under radiation of light-emitting diode emitters with a phytospectrum and white light. A high-pressure sodium lamp was taken as a control source. Lack of valid differences between this data is found out. The article discusses data of literature where effect of heat radiation on plant productivity was discovered by means of light sources of different generations (metal halide lamps, xenon lamps), which is an additional factor apart from visible radiation spectrum which is capable of influencing photobiological efficiency of lamps. On the basis of data of literature, the role of background natural solar light in greenhouses which can negatively affect spectral efficiency of artificial light sources used for supplementary lighting of plants is discussed. A set of methodological factors influencing spectral efficiency of radiation for plant productivity as well as aspects of selection of lamps for cultivation of plants in greenhouse conditions for different latitudes are reviewed and scientifically validated. A controversy in selection of PAR chromaticity of light sources for plant cultivation is demonstrated. The concept of selecting 2 a light source for plant cultivation based on availability of specific response of plant groups to PAR chromaticity is proposed as the most objective for practical application. © 2019, LLC Editorial of Journal "Light Technik".
