Monitoring Carbon Dioxide in the Greenhouse

In addition to temperatures conducive to growth, light (photosynthetically active radiation; PAR, which was covered in part 3 of this series), water, and nutrients, plants also require carbon dioxide (CO2) for photosynthesis (carbon assimilation), which ultimately affects plant growth, vigor, and vegetable and cut flower yield. Carbon dioxide is an odorless and colorless trace gas. Today, ambient CO2 levels outdoors comprise 0.04% of atmospheric volume, or around 400 μmol∙mol−1 (or parts per million, ppm). Plants take up CO2 by diffusion, through small pores called stomates that are primarily located on the underside of leaves. The opening and closing of stomates can be influenced by leaf and air temperatures, light levels, humidity, water stress, CO2 concentration, and oxygen (O2) in the air and leaf. Thus, if any of these environmental or cultural factors used for photosynthesis are limiting in the greenhouse, plant growth and yield are less. Until recently, the vast […]
