초록

잎새버섯 적정 배지량 구명시험에서 배지량별 균사배양 소요일수는 1kg 30일, 2kg 39일, 2.5kg 42일 및 3kg 45일로서 배지량이 많을수록 배양일수가 늘어났고, 수확 소요일수 또한 93일에서 104일로 늘어났다. 수량에서는 1kg 봉지에서는 103.3g, 2kg 봉지 227.2g, 2.5kg 봉지 245.5g, 그리고 3kg 봉지 312.0g으로 배지량이 증가할수록 수량이 증가하였다. 잎새버섯 발효톱밥 첨가효과 구명시험에서 균사배양 소요일수는 발효톱밥을 첨가한 처리에서 4~7일 정도 빨랐고, 수량은 발효 참나무톱밥을 첨가한 처리에서 함박 1kg 봉지당 145.2g, 잎새1호 121.2g으로 가장 높게 나타났다. 발효활엽수 톱밥 첨가율에 따른 시험관칼럼배지를 이용한 균사생장속도조사에서는 발효활엽수 톱밥을 60%까지 증가시켰을 경우 생장속도가 점점 빨라졌으며, 80% 첨가에서는 다소 낮아지는 경향이었다.

This study was conducted to determine proper amount of media and the effect of fermented sawdust on yield of Grifola frondosa in bag culture. The yield of Grifola frondosa was 227 g for 2 kg of media compared with 103 g for 1kg, 256 g for 2.5 kg, and 312 g for 3 kg. The greatest yield of Grifola frondosa per mass of media was 114 g/kg media for 2 kg of media. Days to harvest for 2 kg of media was 95 days compared with 93 days for 1kg, 99 days for 2.5kg, and 104 days for 3kg. Addition of fermented oak sawdust increased yield from 90 to 145 g/kg bag for Hambak cultivar and from 104 to 121 g/kg bag for Yipsae1ho cultivar. Culture duration was shorten 4-7 days by treating fermented oak sawdust.
