| 摘 要： | 用扫描电子显微镜对朱鹮(Nipponia nippon)不同部位羽毛进行了超微结构观察。结果表明:起飞翔作用的飞羽和尾羽主要由有钩羽小枝和无钩羽小枝构成;有钩羽小枝和无钩羽小枝相互啮合形成坚实的羽面来减少飞行阻力。组成羽冠的颈羽有着特殊的特点,先端羽小枝两侧全部为无钩羽小枝,而后沿着羽轴向根部逐渐变化,出现有钩羽小枝。尾羽的有钩羽小枝中的小钩数绝大多数为4个,纤毛为6对;飞羽的有钩羽小枝中的小钩数绝大多数为5个,少部分为6个,纤毛为6对;颈羽的有钩羽小枝小钩数绝大多数为4个,纤毛为5对。朱鹮的各羽小枝的腹齿数变化较大。羽轴及羽枝轴无明显特征,髓质层由多孔的髓腔构成。

| Abstract: | The microstructure of feathers of Crested Ibis(Nipponia nippon)from different parts of the body was observed with SEM.Results show that remiges and rectrices which function in flying are composed of hooked barbules and non-hooked barbules,and the hooked barbules cross the nonhooked barbules with their barbs to reduce air resistance in flying.For the neck feathers with special characteristics which compose the crest,there are nonhooked barbules on both sides of the tip barbules,and then there are some change... |
