Global warming is progressing due to the increase of greenhouse gases since the industrial revolution. carbon dioxide is a representative greenhouse gas. carbon dioxide is needed by plants for photosynthesis. there are also studies that photosynthesis is active when the concentration of carbon dioxide in the atmosphere is higher than that of the atmosphere. this can be used to increase carbon dioxide absorption in agriculture. there are studies on the absorption of carbon dioxide by houseplants with large leaf areas. studies related to the amount of carbon dioxide uptake of barley, which have a small leaf area, are lacking. therefore this experiment was conducted to investigate the relationship between carbon dioxide absorption and leaf area of barley. the experiment was conducted by dividing the sprouted barley into 3 groups with different growth conditions. sprouts barley were locked in an airtight box at the same time for three days. air was collected immediately after confinement, and air was collected 5 hours later. the collected air was analyzed for carbon dioxide concentration through a gas analyzer. In group C, the amount of carbon dioxide absorbed per unit time and area was high, indicating that the absorption was not only related to the area of the leaf but also other factors.
