600, 700, 800, 900, $1000{mu}g/50g$ 무기셀레늄($Na_2SeO_3$)의 배지처리에 의한 노랑느타리버섯 균사배양기간, 균사밀도, 초발이소요일수, 유효경수, 개체중, 유기셀레늄 전이량을 조사한 결과는 다음과 같다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 균사배양기간은 대조구 22일에 비하여 $600{sim}1000{mu}g/50g$처리는 3~8일까지 농도가 진할수록 배양기간이 길어졌다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 균사밀도는 $600{sim}1000{mu}g/50g$처리 까지는 대조구와 동일하게 보통이었다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 초발이소요일수는 $600{sim}1000{mu}g/50g$처리는 대조구 5일에 비해 3~8일 까지 농도가 진할수록 초발이소요일수가 길어졌다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 유효경수는 $600{sim}1000{mu}g/50g$처리는 10~16개로 대조구 18개에 비해 2~8개 까지 농도가 진할수록 유효경수가 적어졌다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 수량(개체중)은 $600{sim}1000{mu}g/50g$ 처리는 94~166g/850cc로 대조구 123g/850cc에 비해 5.7~23.5%까지 농도가 높을수록 수량이 감소되었다. $Na_2SeO_3$의 처리에 의한 노랑느타리버섯 축적된 유기셀레늄 량은 $600{sim}1000{mu}g/50g$처리까지 $9.1{sim}10.8{mu}g/g/dry$로 농도가 높을수록 대조구 $0.05{mu}g/g/dry$에 비해 182~216배까지 축적되었다. 결론적으로 노랑느타리버섯 균사배양기간, 균사밀도, 초발이소요일수, 유효경수, 개체중, 유기셀레늄 전이량은 $600{sim}1000{mu}g/50g$에서 억제되는 경향이 나타남에 따라 가장 적당한 농도는 $600{sim}1000{mu}g/50g$보다 낮은 $400{mu}g/50g$이라고 본다.
The research for incubation period, mycelial density, day required for primordial formation after inoculation(below DPI), number of valid stipes, individual weight and accumulation amounts of organic selenium for P. cornucopiae by treating 600, 700, 800, 900, 1000(${mu}g/50g$) of $Na_2SeO_3$ is following. Incubation periods of P. cornucopiae are 25~30 days per each treatment with $Na_2SeO_3$. Compared to the control which took 22 days of incubation period, it is increased 3 or 8 days for the treatment of $600{sim}1000{mu}g/50g$. Mycelial density of P. cornucopiae treated with $Na_2SeO_3$ between 600 and $1000{mu}g/50g$ is very similar with control. DPI of P. cornucopiae treated with $Na_2SeO_3$ between 600 and $1000{mu}g/50g$ was increased 3 or 8 days. Number of valid stipes of P. cornucopiae treated with $Na_2SeO_3$ between 600 and $1000{mu}g/50g$ was between 10 and 16. It was decreased 2 or 8 as compared to 18 of control. Individual weight of P. cornucopiae treated with $Na_2SeO_3$ between 600 and $1000{mu}g/50g$ was between 94 and 116g/850cc. It was decreased 5.7~23.5% as compared to 123g/850cc of the control. Accumulation amount of organic selenium for P. cornucopiae treated with $Na_2SeO_3$ between 600 and $1000{mu}g/50g$ was $9.1{sim}10.8{mu}g/g/dry$. It was increased 182~216 times as the concentration increased when compared to $0.05{mu}g/g/dry$ of the control. In conclusion, incubation period, mycelial density, DPI, number of valid stipes, individual weight and accumulation amounts of organic selenium for P. cornucopiae by treating $600{sim}1000{mu}g/g$ of $Na_2SeO_3$ was decreased. So that the optimal treatment was less $400{mu}g/g$ than $600{sim}1000{mu}g/g$.
