"Manipulation of stomatal density to improve CO2 uptake in strawberry and blueberry"

大量研究表明，通过增加光合作用的碳同化，可以提高作物产量。吸收二氧化碳进行同化是通过叶表面称为气孔的小孔来控制的。气孔由一对特殊的细胞(保卫细胞)组成，它们之间有一个孔，位于植物的大部分地上部分，但最普遍的是在(较低的)叶表皮上。一些物种的气孔密度(SD)的改变，包括水稻和大麦等作物，已被证明通过改善气体扩散和提高水分利用效率来增加光合作用。因此，增加SD有可能显著提高草莓和蓝莓的产量，并改善浆果品质的一致性。

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.
