Light emitting diode (LED) lighting technology for crop production is advancing at a rapid pace, both in terms of the technology itself (e.g., spectral composition and efficiency), and the research that the technological advances have enabled. The application of LED technology for crop production was first explored as a tool for improving the safety and reliability of plant-based bioregenerative life-support systems for long duration human space exploration. Developing and optimizing the lighting environment (spectral quality and quantity) for bioregenerative life-support applications and other controlled environment plant production applications, such as microgreens and sprout production, continues to be an active area of research and LED technology development. This study examines the influence of monochromatic and dichromatic red and blue light on the early development of six food crop species; Cucumis sativa, Solanum lycopersicum, Glycine max, Raphanus sativus, Pisum sativum, and Capsicum annum. Results support previous findings that light responses are often species specific. The results also support the assertion that monochromatic light can interfere with the normal interaction of various photoreceptors (co-action disruption) resulting in intermediate and sometimes unpredictable responses to a given light environment. The nature of the responses reported inform both bioregenerative life-support designs as well as light quality selection for the production of controlled environment crops.

用于作物生产的发光二极管 (LED) 照明技术正在快速发展，无论是在技术本身（例如光谱成分和效率）方面，还是在技术进步所带来的研究方面。 LED 技术在农作物生产中的应用最初是作为一种工具来探索的，用于提高长期人类太空探索中基于植物的生物再生生命支持系统的安全性和可靠性。为生物再生生命支持应用和其他受控环境植物生产应用（例如微型蔬菜和芽苗生产）开发和优化照明环境（光谱质量和数量）仍然是研究和 LED 技术开发的活跃领域。本研究探讨了单色和二色红光和蓝光对六种粮食作物早期发育的影响；黄瓜、番茄、大豆、萝卜、豌豆和辣椒。结果支持了之前的发现，即光反应通常是物种特异性的。研究结果还支持这样的观点，即单色光会干扰各种光感受器的正常相互作用（相互作用破坏），从而导致对给定光环境产生中间的、有时是不可预测的反应。所报告的响应的性质为生物再生生命支持设计以及受控环境作物生产的光质量选择提供了信息。
