Morphometric procedures were used with scanning electron microscopy backscattered images to study silica bodies in epidermal long cells of four different leaf veins of 17 of the 20 species of Oryza. The veins studied were midrib, large vein, small vein, and marginal vein. Image analysis was used to study morphological variations among the silica bodies. Statistical analyses were based on 11 variables. Even within a single leaf, silica bodies were not uniform. However, the degree of morphological variation normally showed a distribution of morpholgical types around one modal shape. The most significant differences observed were between silica bodies of the midrib and those of other veins. Bodies varied with respect to both size and shape. Computer-assisted image analysis is an effective tool for categorizing basic data and for statistical analysis of variation among silica bodies. Morphological variation among silica bodies of a single leaf may be related to water-conducting systems and their influence on silica availability and phytolith formation.
采用扫描电子显微镜背散射图像的形态计量程序，研究了 20 种稻属中的 17 种的四个不同叶片叶脉的表皮长细胞中的硅体。所研究的叶脉为中脉、大脉、小脉和边缘脉。图像分析用于研究硅体之间的形态变异。统计分析基于 11 个变量。即使在单个叶片内，硅体也不是均匀的。然而，形态变异的程度通常在围绕一个形态类型的分布中显示出形态类型的分布。观察到的最显著差异是中脉硅体与其他叶脉硅体之间的差异。硅体在大小和形状上都有所不同。计算机辅助图像分析是对基础数据进行分类和对硅体之间变异进行统计分析的有效工具。单个叶片的硅体形态变异可能与导水系统及其对硅的可用性和植硅体形成的影响有关。
