3种犬科动物直针毛显微形态学特征观察

应用扫描电镜及偏振光显微镜对沙狐、狼和貉的背部和腹部直针毛的髓质指数及鳞片花纹类型进行研究。结果表明。沙狐2个部位的髓质指数区间为71．4％～82．9％，狼的为43．6％一62．9％，貉的为51．2％～66．7％；毛鳞片形态在属间和种间存在差异，同一种类身体不同部位毛的鳞片形态也有差异，同一根毛的不同部位也存在差异，沙狐背毛主要鳞片类型为方瓣型，腹毛主要鳞片类型为长瓣型；狼背毛的主要鳞片类型为方瓣型，腹毛的主要鳞片类型为杂波形；貉背毛的主要鳞片类型为杂波型、杂瓣型，腹毛的主要鳞片类型为杂波形。用毛的显微形态学特征对3种动物进行识别具有可行性，但有一定的难度。

Observation of Microscopic Morphologic Characters of Straight Guard Hair of 3 Species of Canid

The medullary index and scale pattern of straight guard hair's from the back and the abdomen of the corsac fox(Vulpes corsac),wolf(Canis lupus) and Nyctereutes procyonoides(Nyctereutes procyonoides) were studied by scanning electronic microscope and polarizing microscope.The medullary index interval of hairs from the back and the abdomen of corsac fox was between 71.4% and 82.9%,the same index in wolf was between 43.6 and 62.9%,in Nyctereutes procyonoides was between 51.2% and 66.7%;At the same time,the res...
