为了解LED光质对石蒜主要生理指标的影响,以3组不同大小的石蒜鳞茎为材料,研究了在3种LED光源光照条件下可溶性蛋白含量、可溶性糖含量和淀粉含量的变化。结果表明,蓝光、红+蓝混合光有利于提高鳞茎的可溶性蛋白含量,红光有利于提高可溶性糖含量;与红+蓝混合光相比,红光 In order to understand the effect of LED light quality on the main physiological indexes of Lycoris radiata, the changes of soluble protein content, soluble sugar content and starch content in three kinds of Lycoris bulbs were studied under the illumination of three kinds of LED light sources. The results showed that the mixed light of blue light, red and blue could improve the content of soluble protein in the bulb, and the red light was beneficial to increase the content of soluble sugar. Compared with the mixed light of red and blue, the red light
