摘　　要：采用扫描电镜观察和方差分析研究了不同生境条件下海南粗榧(Cephalotaxus mannii Hook.f.)成熟叶表面结构,结果表明:海南粗榧叶表面气孔为12—15列,多数为14列;气孔结构为完全或不完全的双环型气孔或单环型气孔,其大小变化较大;副卫细胞2—6个(多数为2个),大小变化也较大。The mature leaves' surface of the five Cephalota.rus mannii population growing in different environment was studied with a scanning electron microscope and analysis of variance.The result shows that one leaf has two bands of stoma and one band includes 12-15 column of stoma that is complete or not complete double-circle stoma or single circle stoma whose size is changeable.One stoma has 2-6 subsidiary cells whose size varies greatly.
