Abstract
-
Nitric acid rain is a product of nitrogen oxide, a greenhouse gas, when it reacts with water in the atmosphere. Studies of acid rain on Helianthus annuus, the common sunflower, have found negative effects on plant growth, but those were a result of sulfuric acid rain. Sunflower sprouts were grown in a greenhouse beside a control group and watered with dilute nitric acid with pH3-4 and measurements were compared to the control group over the course of nine weeks. The significant differences were in stem height, midday leaf photosynthesis, midday leaf transpiration, and total shoot biomass. Had the study continues further there is evidence that a few more measurements would have become significant. Acid rain from the release of nitrogen oxide into the atmosphere could have adverse effects on sunflowers and industries that rely on them in the future.
