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(㎍/50g) of Na2SeO3 is following. Incubation periods of P. cornucopiae are 25~30 days per each treatment with Na2SeO3. Compared to the control which took 22 days of incubation period, it is increased 3 or 8 days for the treatment of 600~1000㎍/50g. Mycelial density of P. cornucopiae treated with Na2SeO3 between 600 and 1000㎍/50g is very similar with control. DPI of P. cornucopiae treated with Na2SeO3 between 600 and 1000㎍/50g was increased 3 or 8 days. Number of valid stipes of P. cornucopiae treated with Na2SeO3 between 600 and 1000㎍/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 Na2SeO3 between 600 and 1000㎍/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 Na2SeO3 between 600 and 1000㎍/50g was 9.1 ~ 10.8㎍/g/dry. It was increased 182~216 times as the concentration increased when compared to 0.05㎍/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~ 1000㎍/g of Na2SeO3 was decreased. So that the optimal treatment was less 400㎍/g than 600~ 1000㎍/g.
