Abstract
The LED lighting systems are regarded as perspective light sources for known and projectable space greenhouses (SG), as well as terrestrial greenhouses and plant factories on the Earth. At the same time, inconsistency of information about physiological effects produced by LED lighting and irregular character of plant responses to LED lighting have so far restricted the application of LED light systems. This review provides an analysis of the current concepts concerning the role of light for photoautotrophic plants and paths of interaction between different plant light perception systems. We summarize the accumulated knowledge about the main reactions of plant species to narrow-band lighting. We also provide an analysis of the basic parameters of plant lighting regimes – photosynthetic photon flux density, photoperiod, light spectrum and pulsed light vs continuous light – and their influence on crop light use efficiency. We discuss possible quantitative criteria for the evaluation of plant lighting regime quality inside the SG, and highlight the importance of statistical methods of experimental data analysis and the need to minimize the number of optimized parameters. Multi-factorial plant experiments and posterior regression analysis can be a convenient approach to optimize LED irradiation inside space greenhouses.
期刊介绍：
The Official Human Space Exploration Review Journal of the International Academy of Astronautics (IAA) and the International Astronautical Federation (IAF) REACH – Reviews in Human Space Exploration is an international review journal that covers the entire field of human space exploration, including: -Human Space Exploration Mission Scenarios -Robotic Space Exploration Missions (Preparing or Supporting Human Missions) -Commercial Human Spaceflight -Space Habitation and Environmental Health -Space Physiology, Psychology, Medicine and Environmental Health -Space Radiation and Radiation Biology -Exo- and Astrobiology -Search for Extraterrestrial Intelligence (SETI) -Spin-off Applications from Human Spaceflight -Benefits from Space-Based Research for Health on Earth -Earth Observation for Agriculture, Climate Monitoring, Disaster Mitigation -Terrestrial Applications of Space Life Sciences Developments -Extreme Environments REACH aims to meet the needs of readers from academia, industry, and government by publishing comprehensive overviews of the science of human and robotic space exploration, life sciences research in space, and beneficial terrestrial applications that are derived from spaceflight. Special emphasis will be put on summarizing the most important recent developments and challenges in each of the covered fields, and on making published articles legible for a non-specialist audience. Authors can also submit non-solicited review articles. Please note that original research articles are not published in REACH. The Journal plans to publish four issues per year containing six to eight review articles each.
