摘　　要：光质对植物的形态建成、光合作用、物质代谢、基因表达以及内源激素水平的产生均有调控作用,马铃薯试管薯形成、块茎膨大期物质积累连同光合作用产物的输送都依赖于光质的调节作用。基于组织培养技术生产的马铃薯试管薯是构建种薯工厂化生产的主要途径,探索光质影响试管薯生育进程的机制,将有助于从物理光谱角度提升试管薯产量与质量。综述讨论了单色光和组合光对试管薯形成的影响,同时探讨光受体对试管薯形成的分子作用机制,为马铃薯试管薯诱导专用光源的开发提供理论依据。Light quality has a regulatory effect on plant morphogenesis,photosynthesis,metabolism,gene expression and endogenous hormone levels.Light quality plays an important regulatory role in potato microtuber induction,dry mater accumulation during bulking stage,and photosynthate transport.Potato microtuber production based on tissue culture technology is the main way to construct seed potato factory production.Exploring the mechanism of light quality affecting the growth process of microtuber will help in improving the yield and quality of microtuber from the perspective of physical spectrum.This review discussed the effects of monochromatic light and combined light on the formation of microtubers and explored the molecular mechanism of light receptors in the formation of microtubers.It provides a theoretical basis for the development of special light source for microtuber induction.
