Abstract

톱밥종균, 성형종균 및 액체종균 등을 사용함에 따른 생산성 차이를 조사하기 위해 연구하였다. 배양 중의 배지오염 여부를 확인한 결과, 액체종균 접종구에서는 오염이 없었고 톱밥종균과 성형종균 접종구의 오염율은 각각 6.7%였다. 3주기에 걸친 버섯 발생작업을 통해서 톱밥종균, 성형종균, 액체종균 접종구에서 각각 725.1g, 726.2g, 573.9g의 버섯을 수확했다. 배지당 버섯발생 개체수는 톱밥종균과 성형종균 접종구의 배지들에서 57.4개, 64.3개가 발생한 반면에 액체종균 접종구에서는 45.1개가 발생했다. 배지당 버섯수확량에 있어서 톱밥종균 접종구에서는 1,000g 이상 수확된 배지가 없지만 성형종균과 액체 종균에서는 배지의 13%와 7%로. 나타났다. 그리고 톱밥종균 접종구 배지의 79%, 성형종균 접종구 배지의 53%, 액체종균 접종구 배지의 33%에서 <TEX>$600{\sim}999g$</TEX>의 버섯이 수확되었다. 발생 주기에 따른 수확량을 비교해 보면, 액체종균 접종구는 다른 두 접종구에 비해 1주기에서는 수확량이 적은 반면에 2주기 및 3주기에는 수확량이 오히려 더 높은 것으로 나타났다. This study was made to investigate the difference of the shiitake productivity according to the use of sawdust, plug-shaped and liquid spawn. Contamination of medium was confirmed by eye. There was no contamination in the liquid spawn treatment. And, contamination rates in the sawdust spawn and plug-shaped spawn were 6.7%, respectively. Productivity of fruit-bodies was 725.1 g from sawdust spawn, 726.2 g from plug-shaped spawn and 573.9 g from liquid spawn until 3rd flushing of fruit-bodies. The number of fruit-bodies was 57.4 per medium of sawdust spawn, 64.3 plug-shaped spawn and 45.1 liquid spawn. At yield per medium, the percentage of media producing over 1,000 g was 13% in plug-shaped spawn and 7% in liquid spawn. However, there was no medium producing over 1,000 g of fruit-bodies in sawdust spawn. Fruit-bodies of <TEX>$600{\sim}900g$</TEX> were yielded from 79% of sawdust spawn treatment, 53% plug-shaped spawn and 33% liquid spawn treatment. When compared the productivity of fruit-bodies, liquid spawn treatment appeared lower than sawdust spawn and plug-shaped spawn treatment at 1st flushing, but appeared higher than the others at 2nd and 3rd flushing.
