Light, especially light quality, has a significant impact on morphogenesis and yield formation during potato micropropagation. It is also one of the key environmental factors that are indispensable and artificially controllable during potato micropropagation. At present, the production of virus-free seed tups based on tissue culture is the main way to obtain potato original seed. Therefore, it is of great value to explore the influence of spectrum on the regulation of potato micropropagation. This paper aims to summarize the research on the regulation of potato micropropagation in recent years, combined with the author's research experience, analyze and discuss its research progress and problems in the research, in order to summarize predecessors' research experience, and find more relevant research direction of needs research and production, potato micro numerous fill light spectra for the future to choose to offer reference to research and application.
