G basal medium, CB common buckwheat, FCB fermented common buckwheat, TB tartary buckwheat, FTB fermented tartary buckwheat. For each parameter, values in the same column with asterisk star (* or **) are significantly different (p < 0.05 or p < 0.01) from basal medium (G). Each mean value was written with standard error of the mean (SEM). ^† $\text{Total size index}=(Mushroomweight\times Pileusdiameter\times Stipelength\times Stipethickness)/100$
