Influence of Particle Size and Different Substrates Containing Tea Waste on Yield and Some Morphological Characters of Ganoderma lucidum Mushroom

Abstract

The objective of this study was to determine the effects of substrates prepared by the mixtures of sawdust and wood-chip of oak with tea manufacture waste (TW) at the rate of 10, 15, 20 and 25% on the yield and some morphological characters of Ganoderma lucidum mushroom. Ganoderma lucidum was obtained from Company of Agromycel in Denizli. In the study, pH, moisture, N and C contents, and C:N ratios of substrates, and also days to first fruiting, yield and some morphological characters were determined. Substrate mixtures of sawdust (OS) and wood-chip (OWC) of oak at the rate of 80% with 18% wheat brain (WB), 1% sucrose and 1% CaCO3 were used as their controls. The highest mushroom yield was obtained from 90 OWC:10 TW (73.07 g/kg substrate) and 75OS:25TW (21.21 g/kg substrate). It was determined that mushroom yields of the substrates, except for the mixtures of 80:20TW, 85:15TW and 90:10TW prepared by oak sawdust with tea waste, were higher than that in control substrate of 80:18WB.
