用扫描电镜对栽培稻的两个籼型品种（Ｏｒｙｚａｓａｔｉｖａｓｕｂｓｐ．ｉｎｄｉｃａ）、普通野生稻（Ｏ．ｒｕｆｉｐｏｇｏｎ）、药用野生稻（Ｏ．ｏｆｆｉｃｉｎａｌｉｓ）、疣粒野生稻（Ｏ．ｍｅｙｅｒｉａｎａ）及野生稻与栽培稻的种间杂种Ｆ１的外稃表面显微特征进行了比较研究，观察到外稃表面的显微特征有明显的种间差异，并初步概述了三种野生稻的乳突特征。栽培稻与野生稻的种间杂种外稃显微特征受亲本影响，其中乳突座间距、列宽主要受野生稻亲本影响；底座以上的峰突特征如峰距、峰数则表现为栽培稻亲本的特征；乳突分布密度表现为超亲现象。
Scanning electron microscopy (SEM) was used to study the effects of two indica rice cultivars (Oryzasativasubsp. Indica, O.rufipogon, O.officinalis, O.meyeriana, The microscopic characteristics of the outer surface of interspecific hybrid F1 of cultivated rice were compared. The microscopic characteristics of the surface of the outer cricket were observed to be significantly different from each other. The characteristics of the three types of wild rice were summarized. The microscopic characteristics of interspecific hybrid nephew of cultivated rice and wild rice were influenced by their parents. The distance between mastoid and the width of mast were mainly affected by the parents of wild rice. The characteristics of peak processes such as peak distance and peak number above the pedestal appeared as cultivated rice The characteristics of the parents; mastoid density distribution showed super-progenitor phenomenon.
