| 英文摘要 | The beneficial effects of elevated CO2 on plants are expected to be compromised by the negative effects posed by other global changes. However, little is known about ozone (O-3)-induced modulation of elevated CO2 response in plants with differential sensitivity to O-3. An old (Triticum aestivum cv. Beijing 6, O-3 tolerant) and a modern (T. aestivum cv. Zhongmai 9, O-3 sensitive) winter wheat cultivar were exposed to elevated CO2 (714 ppm) and/or O-3 (72 ppb, for 7h d(1)) in open-topped chambers for 21 d. Plant responses to treatments were assessed by visible leaf symptoms, simultaneous measurements of gas exchange and chlorophyll a fluorescence, in vivo biochemical properties, and growth. It was found that elevated CO2 resulted in higher growth stimulation in the modern cultivar attributed to a higher energy capture and electron transport rate compared with the old cultivar. Exposure to O-3 caused a greater growth reduction in the modern cultivar due to higher O-3 uptake and a greater loss of photosystem II efficiency (mature leaf) and mesophyll cell activity (young leaf) than in the old cultivar. Elevated CO2 completely protected both cultivars against the deleterious effects of O-3 under elevated CO2 and O-3. The modern cultivar showed a greater relative loss of elevated CO2-induced growth stimulation due to higher O-3 uptake and greater O-3-induced photoinhibition than the old cultivar at elevated CO2 and O-3. Our findings suggest that the elevated CO2-induced growth stimulation in the modern cultivar attributed to higher energy capture and electron transport rate can be compromised by its higher O-3 uptake and greater O-3-induced photoinhibition under elevated CO2 and O-3 exposure. |
