Abstract

This studies investigated the effect of concentrations of sodium chloride (NaCl) on occurrence and growth of fruitbody in oyster mushrooms, Pleurotus spp. Our experiments divided into two parts. When the water contents in substrate were added with sodium chloride solution in cotton waste box cultivation as a first experiment, the growth of mushroom was damaged as the concentration was increased, even though there was a little difference according to the strains. The yield in 1.0% NaCl solution was decreased to 72% compared to non-treated plot while that in 3.0% solution was only 2% of the non-treated plot. Morphological characteristics of mushrooms cultivated in substrate with the different concentration of the solution showed different results. For example, the size and thickness of pilei were not influenced by NaCl concentration, but the length of stipes and individual weight were much influenced. In plastic box cultivation filled with cotton waste, watering treatment with the different concentrations of sodium chloride solution, the second experiment, did not show any difference according to the concentration until 1.0% solution but there was a little difference according to the strains. The productivity of fruitbody started to decrease at 2.0% of the solution and the yield and quality of mushroom in 3.0% solution treatment were generally low. After the second flush, days for mushroom sprouting were generally prolonged in proportion to the solution concentration. Taken altogether, the second experiment did not show a clear effect as the case of the first experiment.

본 연구는 폐면 상자재배에서 NaCl 농도가 느타리 버섯 균사생장 및 자실체 발생과 생육에 미치는 영향에 관한 것으로 폐면 상자재배에서 NaCl 농도별로 조절된 물로 배지 수분을 조절하는 경우에는 농도가 높아짐에 따라 버섯생육에 장해를 일으키는 경향을 보였으며, 품종에 따라 약간의 차이는 있으나 시험한 느타리버섯의 전체를 백분율로 계산할 때 자실체 수확은 무처리구에 비하여 1.0% 처리구의 수확량은 72% 정도로 급격히 감소하였고, 3.0% 처리에서는 2%로 거의 수확할 수 없었다. NaCl 농도별 자실체의 형태적 특징은 갓크기, 갓두께는 처리농도에 따른 차이는 업었으며, 대길이와 개체중에서는 농도에 따른 확실한 차이를 보였다. NaCl 농도별 관수처리의 수량성에서는 1.0% 처리까지는 품종 간에 약간의 차이는 있으나 전체적으로 농도에 따른 차이를 볼 수 없었으며, 2.0% 처리에서 다소 수량이 감소되는 경향을 보이고 3.0% 처리에서는 전체적으로 수량과 버섯품질이 떨어지는 현상이 있었다. 버섯 초발이소요일수는 2주기에서는 NaCl 농도가 높아짐에 따라 발이 기간도 길어지는 경향을 보이나 버섯품종에 따라 다소 차이는 있으며, NaCl의 배지중 처리와 같이 확실한 차이는 나타내지는 않았다. NaCl 농도별 관수처리에 의한 자실체의 형태적 특징은 배지 중 처리와 유사한 경향이나 명확한 차이를 보이지 않았다.
