摘　　要：利用钢直尺、H6303i生物显微镜及配套的图片处理、测量软件系统(重光数码显微系统),测量紫貂(Martes zibellina)、松貂(Martes martes)和美洲貂(Martes americana)的背中部冬季直针毛长度、细度、近毛根细度、髓质细度、毛根无髓段长度及各类型鳞片比例等形态学指标;使用SPSS19.0对比分析测定数据。结果表明:紫貂、松貂和美洲貂的直针毛均呈典型纺锤型,髓质花纹类型均为网格型-B,鳞片类型、排列顺序、主要鳞片类型相近。松貂直针毛的长度、细度、髓质细度、毛根无髓段长度、扁平型鳞片比例显著高于紫貂(P<0.05),而瓣状型鳞片比例明显低于紫貂,在其他性状方面二者差异不显著(P>0.05);美洲貂的直针毛细度、扁平型鳞片比例显著低于松貂(P<0.05),毛长度、髓质细度、近毛根细度、髓质指数等性状方面二者差异不显著(P>0.05);紫貂和美洲貂只在直针毛的细度上表现出明显的差异(P<0.05)。By using ruler,microscope photography and its supporting software for photo processing and measuring,we collected and analyzed morphological characters of the guard hair including cuticular scale pattern and proportion,the length of the hair and non-medulla bottom as well as the diameter of the hair,near hair root and medulla.All the measurements were carried out.SPSS19.0 statistic software was applied to analyze these collected data.We found the guard hair of sable,pine marten and American marten were showed typical spindle-shaped,medulla pattern type were meshed-B,and the order and types of scales and the main types of scales were similar.The analysis indicated a significant difference in the length of the hair and non-medulla bottom,the diameter of the hair,near hair root and medulla,the proportion of flat type scales and valve type scales between the pine marten and sable（P〈0.05）.It＇s similar in other guard hair traits（P〉0.05）.American marten in hair diameter and the proportion of flat type scales were significantly lower than pine marten（P〈0.05）.Other guard hair traits,such as the length of the hair and non-medulla bottom,the diameter of medulla,indexes of medulla were not significant difference（P〉0.05）.Sable and American marten only in hair diameter showed a significant difference（P〈0.05）.
