摘　　要：黏菌黏变形体结构对变形运动方式具有影响,在显微镜下观察了长期培养中的5种黏菌的黏变形体的形态及运动特征。结果表明:不同种类的黏菌黏变形体形态差别较大,主要是透明外质的有无、形态规则或不规则。运动特征上有滑动型、流动型和爬行运动方式,运动方式和透明外质结构有关,透明外质较厚很难形成典型的伪足,表现为滑动运动方式,移动速度较慢。The myxamoeba structure of myxomycetes affects movement patterns. The morphology and behavior of myxamoebae of 5 myxomycete species, which were subcultured for a long term, have been observed under the microscope. It is indicated that the morphology of myxamoeba vary with species, mainly differing in the presence or absence of transparent ectoplasm and regularity or irregularity of the shape. Transparent ectoplasm may be responsible for the pattern of movement It is difficult to form typical pseudopodium for myxamoeba with thick ectoplasm, and the myxamoeba exhibits gliding motility with slow speed. The other movement patterns include flowing motility and creeping motility .
