초록

표고 ‘화담’의 톱밥배지 안정생산을 위해 침공처리가 균사배양 및 자실체 생산성에 미치는 영향을 조사하였다. 종균 접종후 배지 온도는 배양 23일에 27.0-28.8℃, CO2농도는 배양 16일에 14.0-15.6%까지 높아진 후 감소하였고, O2농도는 CO2농도와 반대의 경향이었다. 배양기간중 침공횟수가 많을수록 배지의 명도(L값)는 감소하고, 색차(ΔE)와 중량감모율은 증가하였다. 침공처리에 따른 1주기 재배기간은 큰 차이를 보이지 않았지만, 침공처리 횟수가 늘어날수록 자실체 발이수가증가하여 3회침공처리구의 3주기총수량이 605.7 g으로가장우수하였다.

영어초록

The effect of punching treatment on bags containing sawdust medium for the stable production of fruiting bodies of Lentinula edodes 'Hwadam' was investigated. After spawn inoculation, the sawdust medium temperature and CO2 concentration reached 27.0–28.8℃ on the 23rd day of incubation, and 14.0–15.6% on the 16th day of incubation, respectively, decreasing thereafter. The O2 concentration showed an opposite pattern to the CO2 concentration. As the number of punching treatments on the medium increased during the incubation period, the lightness value decreased, and conversely, the color difference and weight loss rate increased. There was no difference in the cultivation period according to the punching treatment. As the punching treatment increased on the sawdust medium, the fruiting body yield increased; a three-time punching treatment produced the best yield with 605.7 g. Thus, proper punching treatment on a sawdust medium during the incubation period can increase the number of fruiting bodies and yield.
