摘　　要：用扫描电子显微镜观察Se处理的巴西蘑菇的形态特征。结果表明,添加30mgkg-1外源Se的巴西蘑菇孢子的长、宽和数量分别比对照增加20.92%、5.41%和114.13%,差异极显著(P<0.01);10和20mgkg-1Se处理的囊状体最大直径、最小直径和数量分别比对照增加34.78%、7.73%、13.40%、15.26%和27.78%、33.33%(P<0.01),菌丝宽平均比对照增加45.90%和50.82%(P<0.01)。扫描电镜观察到Se处理的孢子、囊状体、菌丝表面纹饰结构发生不同程度改变。The effects of exogenous Se on the topography and quantitative characters of Agaricus brasiliensis S. Wasser fruit bodies were studied under scanning electronic microscope （SEM）. When exogenous Se was 30 nag kg^-1 the length, width and number of spores of Agaricus brasiliensis S. Wasser increased by 20.92%, 5.41% and 114.13%, respectively, and had significant difference （P 〈 0.01 ） to the control. When treated with 10-and 20 mg kg^-1 Se, the maximum and minimum diameters and number of the cystidium increased by 34.78% and 7.73%, 13.40% and 15.26%, 27.78% and 33.33% （P 〈 0.01）, respectively, and the minimum width of the mycelium increased by 45.90% and 50.82% （P〈0.01）, respectively. The morphological structures of the spore, cystidium and mycelium varied under SEM.
