Numerous studies on the effects of CO2 enrichment in commercial greenhouses have shown that increased crop yields can be obtained through increased photosynthetic carbon assimilation. The uptake of CO2 for assimilation is controlled through small pores on the leaf surface known as stomata. Stomata are composed of a pair of specialized cells (guard cells) with an aperture between them and are located on the majority of the aerial parts of the plant but most prevalent on the (lower) leaf epidermis. Alteration in stomatal density (SD), in a number of species - including crops such as rice and barley, has been shown to increase photosynthesis by improving gas diffusion as well as improving water use efficiency. Increasing SD, therefore, has the potential to significantly enhance strawberry and blueberry yields and improve the consistency of berry quality.

许多关于商业温室中CO2富集效应的研究表明，通过增加光合作用碳同化可以提高作物产量。用于同化的CO2的吸收通过被称为气孔的叶片表面上的小孔来控制。气孔由一对特化细胞（保卫细胞）组成，它们之间有一个小孔，位于植物的大部分气生部分，但最常见于（下）叶表皮。在一些物种中，包括水稻和大麦等作物，气孔密度的变化已被证明可以通过改善气体扩散和提高水的利用效率来增加光合作用。因此，增加SD有可能显着提高草莓和蓝莓产量，提高浆果质量的一致性。
