Abstract

Six strains among the shiitake varieties developed by the National Institute of Forest Science were used to select suitable varieties for sawdust block cultivation method. After 100 days cultivation (60 days in dark and 40 days in light), the weight loss rate of the sawdust block media was 14.4% (12.8% to 15.7%) in average. After 5 to 7 days of fruiting process, 2~36 primordia per medium were formed. The number of primordium formation was in the following order: Manchuhyang> Sansanhyang> Sanbaekhyang> Bambithyang> Sangjanghyang> Taehyanggo. The stipe length was 41~59 mm as followed by Taehyanggo (59 mm), Sanbackhyang (56 mm), Bambithyang (54 mm), Manchuhyang (53 mm), Sanjanghyang (45 mm) and Sansanhyang (41 mm). Among the strains, Sansanhyang had short and thick stipe. The average weight of fruiting bodies was 33~77 g as following order of Taehyanggo (77 g), Bambithyang (51 g), Sansanhyang (50 g), Manchuhyang (41 g), Sanjanghyang (34 g) and Sanbackhyang (33 g). Mushroom production per 2 kg medium was the highest in Sanbackhyang (473 g) followed by Bambithyang (287 g), Manchuhyang (175 g), Sansanhyang (109 g), Sanjanghyang (78 g) and Taehyanggo (60 g). The hardness of the cap was 1,218 to 1,839 g/10 mm. Taehyanggo was the hardest (1,839 g/10 mm) and Bambithyang was the softest (1,218 g/10 mm). In conclusion, in the cultivation condition of sawdust block medium, mushroom production was good in Sanbackhyang and Bambithyang. Sansanhyang showed good in terms of fruiting body shape.

국립산림과학원이 개발한 표고 품종 6개를 대상으로 사각블럭배지에 적합한 품종을 선발하고자 하였다. 100일째 중량감소율은 평균 14.4% (12.8%~15.7%) 였다. 발생작업 후 5~7일에 발이조사 결과 배지당 2~36개였고, 만추향>산산향>산백향>밤빛향>산장향>태향고 순이었다. 대길이는 41~59 mm였고 태향고>산백향>밤빛향>만추향>산장향>산산향 순으로 길었다. 대길이가 짧고 대두께가 굵은 품종은 산산향이 우수하였다. 개체당 중량은 33~77 g였고 태향고>밤빛향>산산향>만추향>산장향>산백향 순이었다. 2 kg 배지의 생산량은 산백향이 가장 많은 582 g이었고 밤빛향>만추향>태향고>산산향>산장향 순이었다. 버섯 갓의 경도는 1,218~1,839 g/10 mm였고 태향고가 1,839 g/10 mm로 가장 단단하였고 밤빛향이 가장 낮았다. 결론적으로 사각블럭배지 재배조건에서 버섯 생산량은 산백향과 밤빛향이 좋았고, 버섯 형태면에서 산산향이 우수하였다.
