摘 要 ：应用扫描电镜对四个栽培棉种纤维的基部、中部、顶部位进行了观察研究，不同株种成熟纤维的形态差别以中部最为明显，表现出种间的遗传特征。在纤维表面观察到有似梭脊和沟槽的皱纹，它的分布和数量在二倍体棉种（亚洲棉和草棉）与四倍体棉种（海岛棉和陆地棉）间存在明显差异。棉纤维表面的皱纹能增加单纤维间的接触面和摩擦

Abstract:The base,middle and apex parts of fibres in four cotton cultigens were observed and studied by electronic microscopic scanning(EMS).There were distinct morphological differences in the middle parts of mature fibres among different cotton cultigens, which indicated their genetic characteristics.
