Abstract

This study was conducted to establish an appropriate period of use of sawdust spawn at low temperatures and a nutrient supplement medium for cultivation of Lentinula edodes 'Hwadam'. Of the nutrient supplements, the total yield of rice bran (5%) + corn flour (5%) treatments were 673.3 g, which was higher than rice bran (551.6 g) and wheat bran (546.7 g) treatments, respectively. As shown by the growth of Lentinula edodes 'hwadam' during to the sawdust spawn storage period (at 4℃), the period of spawn running, browning, fruiting body formation, and development was 27 d, 81 d, 5 d, and 11-13 d, respectively, regardless of the length of the storage period at 4 ℃. After 3 months of storage of sawdust spawn, the number of fruiting bodies and yield decreased as the storage period increased. Therefore, the period of use of sawdust spawn (at 4 ℃) for the stable production of fruiting bodies of Lentinula edodes 'Hwadam' was a maximum of 3 months.

표고 '화담' 자실체 생산에 적합한 배지 영양원과 톱밥종균의 적정 사용기간 설정을 위하여 수행한 연구결과는 다음과 같다. 자실체 생산에 적합한 배지 영양원은 미강(5%)+옥분(5%) 혼용구로 이때의 수량은 676.3 g으로 미강 단용구(551.6 g) 및 밀기울 단용구 (546.7 g)보다 우수하였다. 톱밥종균 저장기간별 생육결과, 저장기간과 상관없이 배양기간은 27일, 갈변기간 81일, 발이기간 5일, 생육기간 11~13일로 1주기 수확까지 총 124~126일이 소요되었다. 저장 1~3개월 톱밥종균은 3주기 평균발이수 5.2~6.1개, 총수량은 537.8~621.2 g이었는데, 이후부터 발이수와 수량이 감소하여 저장 12개월차에는 평균발이수 2.9개, 총수량 294.4g으로 낮아졌다. 따라서, 표고 '화담'의 자실체 안정생산을 위한 톱밥종균의 적정 사용기간은 1~3개월로 나타났다.
