Interactive Effects of O3 and CO2: Implications for Terrestrial Ecosystems

摘要: The atmosphere supplies plants with CO2 for carbon fixation, producing carbon-containing compounds structure and function of cells; O2 to oxidize these compounds, cellular energy. Recently, human activities have produced increases in both O3, a highly reactive form O2. Ozone CO2, generally “detrimental” “beneficial” effects on plants, respectively. However, the combined impacts gases vegetation are uncertain despite their co-occurrence. To date, O3 CO. usually been defined narrowly terms plant shoot responses (leaf biochemistry, physiology, crop yield or tree biomass). do not exist vacuum, but as part an ecosystem whose condition can be by studying basic processes. Thus, objectives this review are: (1) literature concerning interactive vegetation; and, (2) carry out evaluation context terrestrial processes, i.e., nitrogen cycling.
