Lighting instalations for plants lightculture with additional impulsive radiation https://doi.org/10.33108/visnyk_tntu2018.04.091

Abstract

Results of research of plants radiation conditions in enclosed soil are presented in the paper, block diagram of instalation for measuring of energetic parameters of impulsive light sources (luminary) is shown, energysaving illuminators are chosen. Experimental researches were held with the usage of minigreenhouses type of «Flora». Selective pepper seeds «Claudio» were used as plants. Plants were growing either with constant irradiation or with additional impulsive one. Measurements of plants growth parameters are conducted. According to the results of using of energy of optical measurements it is shown that plants use the larger part of energy for photosynthesis process, the smaller part − for warmth (heat) perception and unregulated process. It is shown that additional impulsive radiation leads to the increase of plants morphometric indices and concentration of chlorophylla a and b and carotenoids.
