| 摘 要： | 对18个不同产地的兴安落叶松种皮微形态进引扫描电镜观察。结果表明,种子背面均为条网状纹饰,腹面为拟脑状纹饰,种孔周围呈条带状皱波纹饰,种孔周围形态存在三种类型。种皮纹饰在种内基本上是稳定的,其中腹面纹饰较背面纹饰的变异幅度大。种皮纹饰特征可以作为兴安落叶松种子鉴定的依据之一。 |

| Abstract: | The micromorphologic features of the seed coats of Larix gmelini from eighteen places were observed under Scanning electron microscope. The dorsal ornamentation of the seed coats are all striped and retioculate. The ventral ornamentation are similar to the cerebelloid. There are three types morpha around seed pores and the ornamentation are striped and wrinkly. The ornamentations are relatively stable in species, but the variation of the ventral ornamentation are wider than the dorsal ornamentation. The ornamentation of the seed coats can be regarded as one of the bases for seeds identification of Larix gmelini . |
