Abstract

The effects of punching treatment on mycelial culture and fruiting body productivity were investigated in a new Lentinula edodes cultivar, "Jadam", in sawdust medium for the stable production of oak mushroom. As the punching volume and number increased, the weight loss rate and color difference increased and the L value decreased. After spawn inoculation, the sawdust medium temperature and CO2 concentration reached their highest values at 33 and 19 days of incubation, respectively. The O2 concentration showed the lowest value on the 14th day of incubation, which was the opposite pattern to the CO2 concentration. As the punching volume and the number increased, the medium temperature and O2 concentration increased, and the CO2 concentration decreased. Higher punching volumes and numbers resulted in higher temperatures and lower CO2 concentrations. The best fruiting body yield was 5 × 70 mm - 30 (punching diameter × depth - number), and the total yield after three cycles was 644.7 g.

표고 신품종 '자담'의 자실체 안정생산을 위해 침공처리가 균사배양 및 자실체 생산성에 미치는 영향을 조사하였다. 침공 직경과 깊이가 크고, 침공수가 많을수록 중량감 모율과 색차는 증가하고 명도는 감소하였다. 종균 접종 후 배지온도는 배양 33일에, CO2농도는 배양 19일에 최고치에 도달하였고, O2농도는 CO2 와 반대의 경향으로 배양 14일에 최저치를 나타냈다. 침공 직경과 깊이가 크고 침공수가 많을수록 배지 품온과 O2농도는 상승하였고, CO2농도는 낮아졌다. 수량성은 5×70 mm-30 처리구에서 644.7 g으로 다른처리구에 비해 가장 높은 수량을 보여 자담의 적정한 침공방법으로 선발하였다.
