Abstract

This study sought to determine the optimal mixing ratio of Korean cultivated Artemisia annua for production of functional oyster mushrooms. After 23 days of cultivation, mycelial growth was 12.7 cm in medium supplemented with 5% A. annua and 12.5 cm in control. Mycelial growth progressively slowed with the addition of A. annua, with barely any growth (2.1 cm) in the presence of 70% A. annua. Mycelial density was high density without significant difference between treatments. The pileus diameter was greater in the presence of A. annua than in the control, but the pileus thickness was only slightly higher compared to the control. The stipes thickness was greatest for 15% A. annua, and the length of stipes was longest at 10% A. annua, but was lower than the value of the control. The L value of the fruiting zone was highest 10% firewood, and the L value of freshwater was highest at 5% A. annua. The fruiting body yield was highest to (122 g/850 ml) in medium supplemented with 5% A. annua but markedly decreased at higher levels of A. annua.

본 연구는 국내에 자생하는 약용식물인 개똥쑥을 배지재료로 활용하여 느타리 재배를 위한 적정 혼합비율을 설정하였다. 개똥쑥의 첨가량에 따른 균사생육과 균사밀도를 조사한 결과 균사생육은 배양 23일 후 개똥쑥 5% 첨가된 배지에서 12.7 cm였고, 대조구인 포플러톱밥+미강(8:2)배지에서는 12.5 cm로 개똥쑥 첨가배지와 균사생육이 거의 비슷하였다. 그러나 개똥쑥 첨가량이 증가할수록 대조구 보다 균사생육이 느렸으며, 개똥쑥 70%에서는 2.1 cm로 거의 생육하지 못하였다. 개똥쑥 첨가량에 따른 균사밀도는 처리간에 뚜렷한 차이가 없이 높은 밀도를 보였다. 개똥쑥의 첨가량에 따른 느타리 자실체 특성을 조사한 결과 갓의 직경은 대조구보다 개똥쑥 첨가에서 높았지만, 갓의 두께는 대조구에서 조금 높았다. 대의 두께는 개똥쑥 15% 첨가에서 가장 높았고, 대의 길이는 개똥쑥 10%에서 가장 높았지만 대조구보다는 낮은 경향을 보였다. 수확기 자실체의 갓과 대의 색도를 측정한 결과 대의 L값은 개똥쑥 10%에서 가장 높았고, 갓의 L값은 개똥쑥 5%에서 가장 높은 경향을 보였고, a, b값은 처리간에 뚜렷한 차이가 없었다. 자실체 수량은 대조구가 119 g/850 ml였고, 개똥쑥 5%에서 122 g/850 ml으로 가장 높았고, 개똥쑥 첨가량이 증가할수록 수량은 감소되었다.
