安徽东流水牛头骨数量特征的研究

对14头安徽东流水牛头骨的数量特征进行了研究,结果表明:东流水牛头骨的21项体尺指标具有聚类特性,其中归成五类的体尺指标分别为头背长、下颔骨间隙宽、鼻后孔宽、角长和头后宽;东流水牛头骨的颅高和额大宽、鼻骨长和额小宽、头深和额长、面宽和下颌间隙宽以及鼻颌宽和鼻后孔宽的体尺相等(p>0.05)。

STUDY OF CHARACTERISTICS ON SKULL OF THE ANHUI DONGLIU ADULT BUFFALO

Quantity characteristics for skull of 14 Dongliu adult buffalos in Anhui province have been studied. Results show that 21skull traits can be divided into 5 groups by cluster analysis. The representative characteristics for the 5 groups are skull dorsal length(48.64+2.54cm), mandible spatic width(MSW, 13.68+1.48cm), choana width(2.16+0.21cm), cornus length(40.46+6.85cm) and distance between mastoids of temporale bones (22.25+1.68cm): However, the variations for the following characteristics are insignificant(p>0.05): changes between hight and distance of two eye-orbits at medial point of dorsal margin on left and right, between distance of medial point of temporale and cornus processes on left and right and nose-bone length (16.54cm), between, skull depth and dorsal length(19.75cm), between zygomatic processes width and MSW (13.86cm), and between choana width and nose-jaw width (6: 80cm).
