Effect of elevated CO2 concentration on photosynthetic characteristics of hyperaccumulator Sedum alfredii under cadmium stress
The combined effects of elevated CO2 and cadmi- um （Cd） on photosynthetic rate, chlorophyll fluorescence and Cd accumulation in hyperaccumulator Sedum alfredii Hance were investigated to predict plant growth under Cd stress with rising atmospheric CO2 concentration.

| description | The combined effects of elevated CO2 and cadmi- um （Cd） on photosynthetic rate, chlorophyll fluorescence and Cd accumulation in hyperaccumulator Sedum alfredii Hance were investigated to predict plant growth under Cd stress with rising atmospheric CO2 concentration. Both pot and hydroponic experiments were conducted and the plants were grown under ambient （350 μL L^-1） or elevated （800μL L^-1） CO2. Elevated CO2 significantly （P 〈 0.05） increased Pn （105%- 149%）, Pnmax （38.8%-63.0%） and AQY （20.0%-34.8%） of S. alfredii in all the Cd treatments, but reduced chlorophyll concentra- tion, dark respiration and photorespiration. After lo days growth in medium with 50 μM Cd under elevated CO2, PSII activities were significantly enhanced （P 〈 0.05） with Pm, Fv/ Fm, φ（Ⅱ） and qP increased by 66.1%, 7.5%, 19.5% and 16.47o, respectively, as compared with ambient-grown plants. Total Cd uptake in shoot of S. alfredii grown under elevated CO2 wasincreased by 44.1%-48-5%, which was positively correlated with the increase in Pn. These results indicate that elevated CO2 promoted the growth of S. alfredii due to increased photosynthetic carbon uptake rate and photosynthetic light- use efficiency, and showed great potential to improve the phytoextraction of Cd by 5. alfredii. |
