成年蓝孔雀肌肉组织学性状分析

摘要

The muscle of back,neck,wing,leg and chest of adult blue peafowls were selected randomly as samples (half male and half female).The observation and determination were conducted by HE staining and transmission electron microscopy.Results indicated that the average of muscle fiber diameters,the per-centage of muscle fiber,cross-sectional area and density of blue peafowl were 39.165μm,1 269.45μm2 , 519.71 n/mm2 ,51.99%.The muscle fiber diameters and cross-sectional area of the male was greater than the female significantly (P0.05).The average length of sarcomere,I band,A band,Z line,H band of blue peafowl were 1.430,0.559, 1.144,0.108,0.162μm.The length of I band,A band,Z line and H band of the male was greater than the female significantly (P0.05)；蓝孔雀肌节长度、I带长度、A带长度、Z线宽度、H 带宽度平均分别为1.430、0.559、1.144、0.108、0.162μm,不同性别间I带长度、A带长度、Z线宽度、H 带宽度雄蓝孔雀极显著大于雌蓝孔雀(P<0.01)；孔雀肌肉不同部位间,背部肌肉肌纤维直径、横截面积最小,密度最大.雄蓝孔雀腿部肌节长度、I带长度、A带长度、Z线宽度、H 带宽度最大.
