Abstract

This study was investigated the growth characteristics of 'Nongjingo' cultivar(Lentinula edodes) according to relative humidity(RH). The color difference of the pileus showed the highest L(Lightness, L) value in RH65 and the a(Redness, a) value in RH95. b(Yellowness, b) values were similar in all treatments. The hardness of pileus is highest at RH95. As the relative humidity increased, the length of pileus and stipe tended to increase. The diameter and thickness of pileus were high at RH95%. The diameter of stipe could not see the big difference in the three treatment groups. This study growth characteristics and yield were increased at higher relative humidity, but quality was decreased. Therefore, must adjust the relative humidity to produce high quality mushrooms.

표고 시설재배에 있어 적정 상대습도를 구명하여 고품질 버섯생산 데이터를 제시하기 위해 상대습도를 달리 처리한 결과는 다음과 같다. 상대습도에 따른 생육특성을 조사한 결과, 갓의 명도값은 RH65%에서 높았고, 적색도는 RH95%에서 높았으며, 황색도는 상대습도 간 유의적 차이가 나타나지 않았다. 갓의 경도는 RH95%에서 높은 경향이었다. 갓직경은 RH95%에서 높게 측정되었고, 갓두께는 RH95%에서 높았다. 대길이의 경우 유의적 차이가 나타나지 않았지만 상대습도가 증가할수록 대길이가 증가하는 경향을 보였으며, 대직경은 RH95%에서 높게 측정되었다. 수량은 RH95%에서 유의적으로 높게 측정되었다. 화고발생률은 상대습도가 낮아질수록 높게 조사되었다. 위의 결과를 통해 RH95%에서 표고 자실체의 크기, 수량이 높게 조사되었지만 버섯의 갓색이 어둡고 화고 발생 비율이 낮은 결과를 나타내어 시설재배에서 고품질의 화고 버섯을 생산할 수 있는 상대습도는 65%와 85%인 것으로 판단되었다.
