用不同剂量６０Ｃｏ－γ射线辐照蜜环菌表明，低剂量（１０～８０Ｇｙ）处理能提高菌丝体内超氧化物歧化酶（ＳＯＤ）活性３．９０％～２９．４０％，降低丙二醛（ＭＤＡ）含量５．００％～２６．３０％，有刺激生长、延缓衰老的效应。高剂量（８０Ｇｙ以上）处理则降低ＳＯＤ酶活性２９．４０％～７０．６０％，提高ＭＤＡ含量１１．７０％～１３５．４０％，过氧化物酶（ＰＯＤ）活性提高２３．１０％～１５３４．６０％，显示抑制生长、促进衰老的效应。 Irradiation of Armillaria mellea with different doses of 60Co-γ ray showed that low dose (10 ~ 80Gy) treatment increased the activity of superoxide dismutase (SOD) in mycelia by 3.90% ~ 29.40% and decreased malondialdehyde (MDA) content of 5.00% ~ 26.30%, stimulate the growth, anti-aging effect. High-dose (over 80Gy) treatment reduced SOD activity by 29.40% -70.60%, increased MDA content by 11.70% -135.40% and peroxidase (POD) increased by 23.10% -1534 .60%, showing inhibition of growth and promote the effect of aging.
