Effects of light on the agronomic traits and texture quality of Grifola frondosa
To explore the optimal light intensity required for the growth and development of Grifola frondosa,the strain HSH4 was used as the test material.During the mycelial growth stage,LED white light with 50,100,200,500,and 1000 lx was used,0 1x(dark)as control.During the mushroom stage,LED white light with 0,50,100,200,500,and 1000 1x and sunlight with 200 1x were used to explore the effects on the growth of mycelial,agronomic traits,texture quality and fruit-ing color of Grifola frondosa.The results showed that the mycelial growth rate and growth potential of Grifola frondosa were significantly better when irradiated with LED white light at 50-100 1x during the mycelial growth stage than when irradiated with dark light.The stage of fruiting body growth,LED white light at 500-1000 1x had higher yield than treat-ment with 0-200 1x,and the fruiting body shape was better.The treatment with scattered sunlight at 200 1x had the highest yield,with single bag yield of 615.33 g,and hardness is 105.8,tyrosinase activity is 668 U·g-1.The mushroom quality was firmer and darker in color.The results showed that 50～100 1x of LED white light was required during the growth of the fungus,and the scattered sunlight at the stage of mushroom emergence made the fungus had higher hardness,with grayish brown color and better shape.
