【摘要】 为探究秀珍菇菌丝富硒培养最适硒添加量，以秀珍菇（Pleurotus pulmonarius）优良菌株‘申秀1号’为研究材料，将母种在含有不同量亚硒酸钠（Na₂SeO₃）的培养基上培养，测定菌丝体生长速度差异。结果表明：秀珍菇母种菌落直径随亚硒酸钠量的增加表现为先增大后减小，菌丝生长速度表现出先促进后抑制的趋势。秀珍菇‘申秀1号’母种富硒培养以亚硒酸钠添加量为40 mg/L,菌丝生长最快，亚硒酸钠添加量≥80 mg/L时，菌丝生长受到显著抑制（P<0.05）。更多还原

【Abstract】 To determine the optimal selenium（Se） supplementation level for mycelial selenium enrichment in Pleurotus pulmonarius, the elite strain "Shenxiu No.1" was cultivated on media containing varying concentrations of sodium selenite（Na₂SeO₃）, and mycelial growth rates were measured. Results demonstrated a biphasic response: colony diameter and mycelial growth rate initially increased then decreased with rising Na₂SeO₃ levels. The optimal Na₂SeO₃ concentration for maximal mycelial growth was 40 mg/L. Significant growth inhibition（P<0.05） occurred at concentrations ≥80 mg/L.更多还原
