Abstract

The cultivation method of shiitake is divided into two methods: log cultivation and sawdust cultivation. Recently, the importance of sawdust cultivation has been highlighted due to problems such as environmental problems, rising labor costs, and a reduced labor force. Among the 24 Sawdust-cultivated Lentinula edodes cultivars in Korea stored by the National Institute of Forest Science, this study was conducted to select excellent cultivars under the sawdust block cultivation method. After inoculation, the sawdust mediums were cultured for 100 days (60 days in dark and then 40 days in light), and only Sanjo 712ho sprouted the primordia on the 10th day of light culture (total 70 days of cultivation). As a result of cultivation, the average total yield of the 24 cultivars were 1,816 g and Sanjo 712ho was 2,267 g. The fruiting body yield was the highest in Sanjo 713ho with 3,443 g followed by Sanjo 710ho (3,355 g). Sanlim 10ho, Sansanhyang, and Sanjo 716ho showed low production with 174, 238, and 214 g, respectively. As a result of investigating the morphological characteristics of the fruit bodies, the fresh weight of Sansanhyang and Bambithyang was about twice as heavy as the overall average, and Sulbaekhyang was about twice as light. Bambithyang was the largest and longest in diameter and length of the stipe, and the thickness of the stem was the thickest in Sanjo 716ho. As for the hardness of pileus, Bambithyang showed the highest value at 1,276 g/5 mm, and Sanjo 711ho showed the lowest value at 542 g/5 mm. In summary, Bambithyang showed the best fruiting body characteristics and Sanjo 713ho showed the highest yield in the sawdust block cultivation method. This study, the cultivar with shortened cultivation periods and cultivars with excellent morphological characteristics and high yields.

표고의 재배방법은 원목재배와 톱밥재배 2가지 방법으로 나뉘는데 최근 환경적문제와 인건비 상승, 노동력 감소 등의 문제로 인하여 톱밥재배에 중요성이 부각되고 있다. 국립산림과학원이 보유하고 있는 한국의 표고톱밥재배 품종 24개 중 사각블럭배지 조건에서 우수한 품종을 선발하고자 실험을 수행하였다. 접종후암배양 60일, 명배양 40일 동안 배양했는데 산조712호는 명 배양 10일 시점(70일 배양)에 발이를 시작하였다. 5차까지 발생한 24개 품종의 자실체 평균 생산량은 약 1,816 g이었고 산조712호는 2,267 g으로 나타났다. 생산량이 가장 높은 품종은 산조713호로 3,443 g이었고 낮은 품종으로는 산림10호, 산산향 그리고 산조716호가 각 174, 238, 214 g으로 큰 차이를 보였다. 자실체의 형태적 특성조사 결과 개체당 생중량은 산산향과 밤빛향이 전체 평균보다 약 2배 무거웠고 설백향은 약 2배 가벼웠다. 갓 직경과 대 길이는 밤빛향이 가장 컸고 대두께는 산조716호가 가장 두꺼웠다. 갓 부위의 경도는 밤빛향이 1,276 g/5 mm으로 가장 높은 수치를 보였고 산조711호가 542 g/5 mm으로 가장 낮게 나타났다. 종합하면 사각블럭배지 조건에서 자실체 특성이 가장 우수한 품종은 밤빛향이었고, 생산량이 가장 좋은 품종은 산조713호였다. 이번 연구로 배양기간이 단축된 품종 그리고 형태적 특성이 우수하거나 생산량이 높은 품종을 확인하였다.
