Fruiting body weight changes with changes in additives content. Closed and open symbols denote wet and dried fruiting body weights cultivated on standard sawdust media supplemented with additives, respectively. The circles, squares, triangles, and diamonds represent the fruiting body weights cultivated on the media supplemented with K, zeolite-1, zeolite-2, and sPB, respectively. The fine and thick solid lines represent wet and dried fruiting body weights cultivated on standard sawdust media supplemented with K and the regression lines were as follows: y ^a = −1.49x ^b + 87.69 (r ^c = −0.89, P ^d < 0.01) and y = −0.07x + 7.55 (r = −0.68, P < 0.01), respectively. The fine long dashed line represents the wet fruiting body weights for zeolite-1, y = 0.03x + 81.54 (r = 0.56, P < 0.01). The fine short dashed line represents the same parameters for zeolite-2, y = 0.03x + 80.72 (r = 0.46, P = 0.047). The large dotted line represents the dry fruiting body weights for sPB, y = −0.02x + 7.65 (r = −0.63, P < 0.01). Standard sawdust media, zeolite-1, zeolite-2, and sPB are described in the text. a Wet or dried fruiting body weights; b additive contents; c, d as in Fig. 1
