Designating the upper or adaxial surface of the lateral organs of plants, such as leaves.

指植物上部或近轴的侧器的表面。

The stomatal index in the adaxial epidermis changed variably during development of cotyledons.

上表皮气孔指数的变化规律不明显；

Plants with the most severe phenotype formed only green organs, with many shoot apices on their adaxial sides.

严重表型的植株只产生绿色的器官，在其近轴面有许多芽。

In Calocedrus and Platycladus, only a single series of inverted vascular bundles were generated in the adaxial side of the bract scale;

在苞鳞中只形成一组倒转的维管束，如侧柏属和翠柏属；

The surface free energy and its component of the adaxial and abaxial surfaces of peach leaves in different growing periods were determined by OWRK method.

应用owrk法对不同生长期桃叶的近轴面、远轴面的表面自由能及其分量进行了测定。
