Abstract
Studies were made to investigate the difference of the shiitake productivity according to the use of sawdust and liquid spawn on middle-temperature type strain. Treatments inoculated with sawdust spawn have shown that yields were dispersed according to flushing periods and fruit-bodies occurred sporadically on medium. However, treatments inoculated with liquid spawn have shown that yield was relatively concentrated at 1st flushing period and fruit-bodies were densely occurred on medium. At total yield and the number of fresh fruit-bodies until seventh flushing, treatments inoculated with liquid spawn were more than those inoculated with sawdust spawn. Also, biological efficiency (B.E.) of inoculation with 20 ml liquid spawn which produced 30% of the medium weight was highest as 69%, but biological efficiency of inoculation with 10 g sawdust spawn was lowest as 42%. And, although rate of fruit-bodies over 10 g in total yield was high on treatments inoculated with sawdust spawn, amounts of fruit-bodies over 10 g were not different among treatments.
중온성 품종을 사용했을 때 톱밥종균과 액체종균의 접종량에 따라 생산성에 어떤 영향을 미치는지를 조사했다. 톱밥종균을 접종한 처리구들은 수확이 차수별로 분산되고 자실체도 산발적으로 발생되었다. 반면에, 액체종균을 접종한 처리구들은 톱밥종균에 비해 상대적으로 수확이 1차 발생에 집중되었고 자실체들도 조밀하게 발생되었다. 7차 발생까지의 총수확량과 버섯 개수도 액체종균 처리구가 톱밥종균 처리구보다 더 많았다. 또한 배지무게의 30%가 생산된 액체종균 20 ml 접종 처리구의 생물적효율은 69%로 처리구들 중 가장 높은 반면에, 톱밥종균 10 g 접종 처리구의 생물적효율은 42%로 처리구들 중 가장 낮았다. 그리고 비록 총수확량 중 10 g 이상 되는 버섯들이 차지하는 비율이 톱밥종균을 접종한 처리구들에서 더 높게 나타났지만, 10 g 이상 되는 버섯의 양은 톱밥종균을 접종한 처리구들이나 액체종균을 접종한 처리구들 간에 큰 차이가 없었다.
