초록

표고 톱밥배지 배양일수별 배지특성을 조사한 결과 '산조701호'의 색도는 명도인 L값이 배양 30일에 83.8(${\pm}2.5$)에서 배양 120일에 45.7(${\pm}2.3$)로 감소하였고, a와 b의 값은 배양일수가 증가할수록 증가하였지만 경도는 배양 30일에 9.4(${\pm}0.9$)g/mm에서 배양 120일에 2.6(${\pm}0.2$)g/mm으로 감소하였다. '농진고'는 명도인 L값이 배양 30일에 86.2(${\pm}2.1$)에서 배양 120일에 53.4(${\pm}1.3$)로 감소하였고, a와 b의 값은 배양일수가 증가할수록 증가하였지만 경도는 배양 30일에 4.8(${\pm}0.7$)g/mm 배양 120일에 3.8(${\pm}1.0$)g/mm로 감소하였다. 배양일수별 자실체 특성을 조사한 결과 '산조701호'의 배양일수별 첫 수확일은 30일 배양배지는 46일, 60일배양 배지는 89일, 90일배양 배지는 8일로 가장 짧았고, 120일 배양배지가 9일이었다. 자실체 평균무게는 90일 배양배지가 48.3 g으로 가장 높았고 갓 직경, 갓 두께도 가장 높았지만 색도측정결과에서는 120일 배양배지에서 발생된 자실체가 가장 우수한 상품성을 보이는 것을 확인하였다. '농진고'는 30일 배양배지가 22일, 60일 배양배지가 18일, 90일 배양배지가 8일로 가장 짧았고, 120일 배양배지는 9일이었다. 따라서 표고의 배지, 자실체 특성 등을 고려할 때 배지의 배양일수가 120일이 안정적인 수량 및 높은 상품성 확보가 가능할 것으로 판단되었다.

This study investigated the characteristics of different cultivars of Lentinula edodes in sawdust culture at different cultivation days. Between cultivation days 30-120, the color of 'Sanjo701ho' displayed a reduction in L value (brightness) from $83.8{\pm}2.5$ to $45.7{\pm}2.3$, values a and b increased, but hardness decreased from $9.4{\pm}0.9g/mm$ to $2.6{\pm}0.2g/mm$. Between cultivation days 30-120, 'Nongjingo' displayed a reduction in L value from $86.2{\pm}2.1$ to $53.4{\pm}1.3$. Values a and b increased with longer cultivation; however, hardness decreased from $4.8{\pm}0.7g/mm$ on day 30 to $3.8{\pm}1.0g/mm$ on day 120. 'Sanjo701ho' was first harvested at 46 days after a 30-, 89 days after a 60-, 8 days after a 90- (the shortest), and 9 days after a 120-day cultivation. The average fruit body weight was the highest on day 90 of cultivation, at 48.3 g, when the diameter and thickness of the mushroom cap also appeared highest. However, the colorimetric results showed that fruiting bodies produced in the culture medium for 120 cultivation days showed the most excellent commercial properties. 'Nongjingo' was first harvested at 22 days after a 30-, 18 days after a 60-, 8 days after a 90- (the shortest), and 9 days after a 120-day cultivation. Therefore, this study determined that a stable quantity of mushrooms with high commerciality can be produced with 120 cultivation days, considering the shiitake culture and the characteristics of the fruit body.
