Abstract

Five to thirty percent of persimmon peels were added to mushroom medium to investigate mycelial growth. Mycelial growth on the medium with persimmon peels was 82~96 mm (28 days) and was slower than that of the control without persimmon peels as, 100 mm (28 days). Mycelial growth time on medium with 5 to 10% persimmon peels was similar to the control without persimmon peels as 28 days but that on medium with 30% persimmon peels was delayed for 4 days. The time of pinhead formations in medium with 10 to 20% persimmon peels was 8 days, the growth time to harvest was 10 days. These results were similar to those of the control without persimmon peels. The sizes of pileus of treatments with 10 to 30% persimmon peels were tend to be smaller compared with the control. The length of stipe of 10% persimmon peels treatment was 89 mm which was shorter than that of the control with 90 mm. The thickness of stipes of 10 to 20% persimmon peels treatments were 36 to 42 mm which were tend to be thicker than that of the control with 42 mm.

본 연구는 지역 특산물인 감과피를 이용한 버섯배지 개발을 위한 기초자료로서 감과피의 이용 가능성을 검토하고자 수행되었으며 감과피는 경상남도 진주시에 소재한 진주단감원예조합으로부터 건조된 것을 수집하여 사용하였고 공시균주는 큰느타리 2312를 사용하였다. 대조구는 시판혼합배지를 사용하였고 건조된 감과피 5%, 10%, 15%, 20%, 25%, 30%이 첨가된 시판혼합배지를 시험구로 사용하였다. 대조구인 시판혼합배지에 비해 시험구인 5%, 10%, 15%, 20%, 25%, 30%의 감과피가 첨가된 시판혼합배지의 총질소 함량은 감과피 첨가량이 증가할수록 증가하는 경향을 나타내었으며 총탄소와 유기물 함량은 큰 차이가 없었고 C/N율은 감과피 첨가량이 증가할수록 감소하는 경향을 나타내었다. 감과피 첨가량에 따른 시험관 내에서의 균사생장을 조사한 결과 대조구인 시판혼합배지보다 감과피가 첨가된 모든 배지에서 균사생장이 느리게 나타났다. 시험구의 혼합배지 중 5% 감과피가 첨가된 배지에서 균사 생장이 가장 빨라지만 감과피 첨가량이 증가할수록 균사 생장속도는 느려지는 경향을 보였다. 감과피 첨가량에 따른 배양일수는 대조구인 시판혼합배지에 비해 감과피를 30%까지 첨가하여도 배양일수와 초발이 소요일수에는 뚜렷한 차이는 없었지만 감과피 첨가량이 증가할수록 배양일이 길어지는 경향을 보였으며 시판혼합배지에 비해 감과피 첨가비율이 증가할수록 갓의 직경과 두께는 감소하고 대의 길이는 짧아지고 굵기는 굵어지는 경향을 나타내었다. 따라서 감과피를 배지자원으로 이용하기 위해서는 감과피 첨가량에 따른 혼합배지의 조성비가 필요할 것으로 생각된다.
