Research Abstract |
Air pollutants such as ozone, sulfuric acid, nitrous acid and polycyclic aromatic hydrocarbons were exposed to Japanese red pine, petunia, tomato, strawberry, eggplant and kidney bean for 1-3 months. Single or multiple pollutants were exposed on the plants in open top chambers or greenhouse. Photosynthetic activities, visual injuries and growth rates of the plant samples were measured before and after the treatments with these pollutants. Pre-treatment with sprays of scavengers of reactive oxygen species such as mannitol has significantly mitigated negative effects of abovementioned air pollutants on plants. The use of mannitol may be a promising technique to protect higher plants from air pollutants.
