| 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(P0.05),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(P0.05);美洲貂的直针毛细度、扁平型鳞片比例显著低于松貂(P0.05),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(P0.05);紫貂和美洲貂只在直针毛的细度上表现出明显的差异(P0.05)。

| Abstract: | 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) . |
