Abstract—The present study was conducted to evaluate the feasibility of using sunflower residues, such as stalk (SS) and meal (SM), in substitution for the conventional materials, such as corn cob and rice bran, in the substrate for Enokitake mushroom Flammulina velutipes. A total of 9 substrates were prepared according to a 3 by 3 factorial design, where 3 rates (0, 50 and 100%) of replacement of rice bran with SM and 3 rates (0, 50 and 100%) of replacement of corn cob with SS were combined. The combination of 0% SM and 0% SS was used as a control group. The results revealed that the cultivation period, fruiting body yield and biological efficiency were affected by SS and SM significantly. The cultivation period in the SM50-SS0 group was much the same as that in the control group, but those in other groups were extended. Fruiting body yield and Biological Efficiency (BE) were greatest in SM50-SS0 group and smallest in SM100-SS100 significantly (P<0.05), and no statistical differences was found among other groups. The eating quality of fruiting bodies was affected neither by SM nor by SS significantly, but a significant interaction was found in umami intensity, umami preference, sweetness intensity and overall impression. In conclusion, the results revealed SM could replace rice bran up to 50% without negative effects on F. velutipes productivity, and suggested that a limited part of corn cob can be replaced with SS.
