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 100, 200, 300, 400, 500(㎍/50g) of Na2SeO3 is following. Incubation periods of P. cornucopiae are 20~23 days per each low concentration treatment with Na2SeO3. Compared to the control which took 22 days of incubation period, it is reduced 1 or 2 days. Mycelial density of P. cornucopiae treated with Na2SeO3 between 100 and 500㎍/50g is very compact. DPI of P. cornucopiae treated with Na2SeO3 between 100 and 400㎍/50g was reduced 1 or 2days, but 500㎍/50g was increased 1 day. Number of valid stipes of P. cornucopiae treated with Na2SeO3 between 100 and 400㎍/50g is between 19 and 20. It was increased 1 or 2, as compared to 18 of control, but 500㎍/50g was reduced to 1. Individual weight of P. cornucopiae treated with Na2SeO3 between 100 and 400㎍/50g was between 129 and 138g/850cc. It was increased 4.9~12.2% as compared to 123g/850cc of the control but 500㎍/50g was 122g/50g. Accumulation amount of organic selenium for P. cornucopiae treated with Na2SeO3 between 100 and 500 ㎍/50g was 2.73 ~ 8.19㎍/g/dry. It was increased 55~164 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 100,~ 400㎍/g of Na2SeO3 was increased, but 500 ㎍/50g was reduced. So more than 500㎍/50g concentration treatments are required research.
