The cultivation period of shiitake () is approximately 120-150 d, which is longer than that of other edible mushrooms. The development of fruiting bodies in shiitake is affected by light exposure. In this study, we investigated the effects of blue light on the production and ergothioneine contents of shiitake mushrooms. Fruiting body production (yield) on the medium irradiated with blue light increased in both cultivars (L808, 555 ± 60 g/3 kg medium; Sanbackhyang, 1090 ± 106 g/3 kg medium). Additionally, blue light increased the ergothioneine contents and antioxidative activities, and the ergothioneine content of L808 (about 2.8 mg/g) was higher than that of Sanbackhyang (about 1.2 mg/g). These results suggest that blue light is effective in shortening the cultivation period and increasing ergothioneine contents during shiitake cultivation.
香菇（）的栽培周期约为120 - 150天，比其他食用蘑菇的栽培周期长。香菇子实体的发育受光照影响。在本研究中，我们调查了蓝光对香菇产量和麦角硫因含量的影响。两个品种（L808，555±60克/3千克培养基；三北향，1090±106克/3千克培养基）在蓝光照射的培养基上的子实体产量（产量）均有所增加。此外，蓝光增加了麦角硫因含量和抗氧化活性，L808的麦角硫因含量（约2.8毫克/克）高于三北향（约1.2毫克/克）。这些结果表明，蓝光在香菇栽培过程中可有效缩短栽培周期并增加麦角硫因含量。
