Canada is a world leader in design and production of controlled-environment facilities for plant growth for**production of greenhouse crops, indoor horticulture, and research in the plant sciences. With the advent of**inexpensive light emitting diodes (LED), more efficient lighting options are becoming available, providing the**potential to revolutionize lighting strategies for plant growth under artificial illumination. Numerous challenges**must be overcome before LED's are optimally used for indoor plant growth. These include providing sufficient**light for rapid photosynthesis while minimizing heat load and electrical costs, and optimizing spectral quality**for proper plant development. A significant development in LED technology is the chip-on-board (COB), solid**state design which boosts photon output, reduces heat load, and enables spectral mixing to optimize plant**development. A leading producer of the COB LED design is URSA Lighting of Vaughan, Ontario. Their**OPTILUX luminaire lamp features an array of 16 LED chips that can be modified to vary spectral mix while**maintaining photon output. The performance of plants under their LED products remains uncertain, and**research is required to evaluate the efficacy of various spectrum options and the optimal intensity for indoor**applications. In this proposal, we request $25,000 to initiate a research collaboration with URSA Lighting to**evaluate the physiological and growth performance of leading crops produced in greenhouse and**enclosed-warehouse settings, and to evaluate performance with leading research plants such as Arabidopsis**thaliana. The results will guide URSA Lighting, and the horticultural industry, in optimizing the use of the new**COB LED systems, enabling them to improve efficiency and yield of plants while cutting producer costs.

加拿大在植物生长受控环境设施的设计和生产方面处于世界领先地位，这些设施用于温室作物、室内园艺和植物科学研究的生产。随着**廉价发光二极管 (LED) 的出现，更高效的照明选项正在变得可用，为人工照明下植物生长的照明策略带来革命性的**潜力。在将 LED 最佳地用于室内植物生长之前，必须克服许多挑战**。其中包括为快速光合作用提供充足的**光线，同时最大限度地减少热负荷和电力成本，以及优化光谱质量**以促进植物的正常发育。 LED 技术的一项重大发展是板载芯片 (COB) 固态设计，可提高光子输出、减少热负荷并实现光谱混合以优化植物生长。 COB LED 设计的领先生产商是安大略省旺市的 URSA Lighting。他们的**OPTILUX 灯具具有 16 个 LED 芯片阵列，可以对其进行修改以改变光谱混合，同时**保持光子输出。 LED 产品下植物的性能仍不确定，**需要进行研究来评估各种光谱选项的功效以及室内**应用的最佳强度。在本提案中，我们请求 25,000 美元启动与 URSA Lighting 的研究合作，以**评估温室和**封闭仓库环境中生产的主要作物的生理和生长性能，并评估拟南芥等领先研究植物的性能* *拟南芥。研究结果将指导 URSA Lighting 和园艺行业优化新型**COB LED 系统的使用，使他们能够提高植物的效率和产量，同时降低生产成本。
