Abstract
|
|
|
The cultivation conditions of shiitake mushrooms (Lentinula edodes ) influence the production and quality of fruiting bodies. We conducted this study to improve the productivity and quality of shiitake mushrooms by modifying the cultivation conditions.
Two types of spawns (sawdust and liquid spawn) were used, and corn flour was used as a nutritional source for the sawdust medium. A blue light-emitting diode (LED; 300 lux) was also used instead of a white LED during the incubation period. Sanbaekhyang was used as the experimental variety. When using corn flour, the mycelial growth rate increased 1.1 to 2.7 times the growth rate of the control up to 21 days of incubation, and the weight loss rate of the media was also higher. Mushroom productivity increased 1.2 times when the liquid spawn was used compared to when the sawdust spawn was used, and the blue LED also increased fruiting body production by 1.1 times compared to the white LED. Mushroom productivity increased when the liquid spawn was used, and the blue LED also increased fruiting body production. Fruiting body weight and the size of the cap were greater when sawdust spawn was used. The fruiting body weight and the stipe diameter were greater when the blue LED was used. Taste analysis showed that the saltiness increased when corn flour was used, and the sourness increased when the blue LED was used.
