摘要
研究和分析了棕色蘑菇（Agaricus brunnescens）ACCC50031的出菇温度、抗病性、子实体农药残留及营养成分。结果表明，供试棕色蘑菇正常出菇温度为2～26℃，对照双孢蘑菇（Agaricus bisporus）2796为12～26℃；接种疣孢霉病菌21d后，双孢蘑菇2796的发病率达36％，而棕色蘑菇无病菇出现。10种农药施用后的检测结果表明，棕色蘑菇的子实体中无农药残留或农药残留量低于国家规定指标。营养成分分析表明，新鲜棕色蘑菇的粗蛋白、总氨基酸和必需氨基酸含量分别为6．14％、3．28％和1．26％，均高于双孢蘑菇2796。
Fruiting temperature, disease resistance capacity, and nutrient composition of Agaricus brunnescens （ACCC50031） and Agaricus bisporus strain 2796 were compared. Fruiting of A. brunnescens occurred between 2-26℃ depending upon the time of year whereas fruiting of A. bisporus occurred within the range 12-26℃. Twenty-one days after artificial inoculation with the fungal pathogen, Mycogone perniciosa, 36% of the A. bisporus mushrooms were affected whereas A. brunnescens showed no evidence of the disease. Crude protein, and total and essential amino acid contents of A. brunnescens were 6. 14%, 3.28% and 1.26%, respectively, which were higher than those detected in A. bisporus. After a single application of pesticides to A. brunnescens, pesticide residues were either undetectable or below the limits set by the Chinese Government.
