| 英文摘要 | C-3 crops are generally considered more sensitive than C-4 crops to the elevated CO2 and O-3, but it is unclear whether the concentrations of phenolic compounds in them are affected. In this paper, an enrichment experiment with open-top chamber was conducted to examine the effects of elevated CO2, O-3, and their combination on the contents of total phenolic compounds and flavone in the leaves of spring wheat (C-3 crop) and maize (C-4 crop). The results showed for spring wheat, the total phenolic contents in its leaves at jointing stage was significantly higher under elevated CO2 and/or O-3, with the sequence of CO2 plus O-3 > O-3 > CO2 > ambient, while at grain-filling stage, the total phenolic content was lower under CO2 plus O-3 than under CO2, O-3, and ambient. The total phenolic content in maize leaves at jointing stage had the similar variation trend with that for wheat, but at grain-filling stage, the total phenolic content was slightly affected by elevated CO2 and/or O-3. The flavone content in spring wheat leaves was significantly lower under CO2 and/or O-3 stress at jointing stage, but had lesser difference at grain-filling stage under the stress. The same variation trend was observed in the flavone content in maize leaves at jointing and grainfilling stages, i.e., CO2 plus O-3 > CO2 > ambient > O-3. C-3 plant was more sensitive than C-4 plant to the CO2 and/or O-3 stress. |
