1. 华盛顿脐橙叶片气孔呈椭圆形。尤里卡柠檬中等叶片的平均气孔长度和宽度为7.04 × 3.08 ~μ；沼泽葡萄柚，8.06 ~2.08 ~μ~；瓦伦西亚橙，8.91 x 3.80~ ~μ；华盛顿脐橙，4.78 × 2.3 μ。~不同类型叶片的气孔长度和气孔宽度均存在极显著差异。2. 对柠檬叶气孔的研究表明，柠檬叶气孔具有复杂的表面结构，这使得计算表面力对喷雾液体的作用比仅根据气孔孔径计算更为困难。基于分子力的证据表明，柑橘的气孔不被水渗透，但可能被油渗透。
1. The stomatal pore in Washington navel orange leaves is elliptical in shape. The average stomatal pore lengths and widths for medium-sized leaves of Eureka lemon were 7.04 x 3.08 ~μ; of Marsh grapefruit, 8.06 x ~2.08 ~μ~; of Valencia orange, 8.91 x 3.80~ ~μ; and of Washington navel orange, 4.78 x 2.3~ ~μ.~ Stomatal pore length and width were both highly significantly different for each kind of leaf. 2. Study of a stoma of a lemon leaf shows that it has a complicated surface structure which makes calculation of the action of surface forces on spray liquids more difficult than if based on stomatal pore size alone. Evidence based on molecular forces indicates that citrus stomata are not penetrated by water but may be penetrated by oil.
