摘要
用扫描电子显微镜观察了中国特有鸟类哈曼马鸡 (Crossoptilonharmani)卵壳的超微结构 ,采用电感偶合等离子体光谱仪测定了卵壳中的化学元素的含量。首次报道哈曼马鸡卵壳结构与元素成分。哈曼马鸡卵壳表面晶体层、栅栏锥体层和卵壳膜层的厚度分别为 9 3、 30 7 1和 6 4 6 μm ,分别占卵壳总厚度的 2 4%、 80 6 %和 17%。在栅栏层有很多蜂窝小孔 ,测量了其直径。卵壳表面的蛋孔形状有圆形、椭圆形和不规则的方形。蛋孔的横断面呈漏斗状。在蛋孔的上半部有一些颗粒状填充物。对哈曼马鸡卵壳中 2 1种化学元素的含量也进行了测定。
By scanning electron microscopy and inductively couple plasma spectrometry (ICP),the ultrastructure and elemental composition of the eggshell of Tibetan Eared pheasant ( Crossoptilon harmani ) have been investigated.The average thickness of the surface layer of crystals,the palisade and cone layer and the eggshell membrane are 9 3?μm,307 1?μm and 64 6?μm respectively,Their proportions to the total thickness of the eggshell 2 4%,80 6% and 17% respectively.There are many vesicular holes in palisade layer,and physiological significance such structure may be of significant to air exchange.The shape of eggshell pore on the surface layer of crystals is circle or ellipsis or irregular square.The fracture surface of eggshell pore is funneled shape.Some granules fill in the upper part of the eggshell pore.The contents of 21 elements in the eggshell is presented in this paper.
