Abstract

We assessed the growth characteristics of Auricularia polytricha 'Geoni' cultivated in a simple greenhouse constructed of polyethylene (PE) without air conditioning (high temperature) and in an air conditioned mushroomhouse. The successful cultivation of A. polytricha 'Geoni' at high temperatures can reduce energy and facility investment costs. The comparison of growth characteristics of the fungi grown under the different temperature conditions revealed that fruit bodies were larger in the higher temperature condition, but were brighter in the lower temperature condition. Additionally, fruit body physiology was found to be not affected by temperature. In the PE greenhouse, the fresh weight of fruit body was higher in mid-June and early July. Therefore, it was possible to effectively control the growth period of the mushrooms during a high-temperature period. The findings indicate the potential to cultivate A. polytricha 'Geoni' in a simple PE greenhouse that is not cooled in summer, thus reducing energy costs.

흑목이 재배가 어려운 고온기에 에너지와 시설투자비용을 절감할 수 있는 재배방법을 틈새소득작물로 알아보기 위해 간이재배사와 공조재배사에서 털목이 '건이'의 재배특성을 비교하였다. 시험은 6월 15일부터 7월 13까지 3일 간격으로 밀폐형 공조시설재배사와 비닐하우스 간이재배사에 톱밥봉지배지(0.9 kg)를 입상하여 7월 26까지 수확하였다. 생육조건은 공조재배사는 온도 $23^{\circ}C$, 습도 90~95% 조건을 유지하면서 1회/일 관수하였고 간이재배사는 2~3회/일 관수로 온도조절시설은 가동하지 않았다. 그 결과 간이재배사에서 재배한 자실체크기는 공조재배사보다 다소 컸으며, 물리성은 큰 차이를 보이지 않았다. 또한 자실체 명도는 간이재배사가 공조재배사보다 낮아 진한색을 나타냈다. 입상시기별로 수량성은 차별화된 경향을 찾을 수 없었으며 하우스 재배사의 경우 308 g/0.9 kg, 공조재배사에서는 252 g/0.9 kg으로 하우스 재배사에서 22% 더 높았다. 따라서 털목이 '건이' 품종은 여름철 냉방기를 가동하지 않는 간이재배사에서 재배가 가능하여 틈새소득작물로 에너지 비용 절감 효과가 기대되었다.
