Abstract

These experiments were conducted to search for the optimum media size and composition for culture of Lentinula edodes (JNM3022). Considering the incubation period and the successful culturing rate, the optimum media size was length 25 $cm{\times}diameter$ 14 cm (weight 2.5 kg). The saturation moisture amount of Oak sawdust was 251 ml/100 g. It is a half of pine sawdust 495 ml/100 g. Considering the hypha growing speed and hypha density, the optimum media composition was Oak sawdust 80%+ wheat bran 20% and Oak sawdust 80%+ rice bran 20% In 10 treatments of media composition. The optimum moisture amount of media for growing Lentinula edodes (JNM3022) was 55%. Injection pipe with 20 holes in media was reduced the incubation periods to 11 days when 20cm length media and 32 days when 30cm length media compare to control. The best method for browning media surface was change temperature condition above $10^{\circ}C$ and punching the vinyl bag. This treat could shortened the browning periods to 54 days.
