“…Since high CO 2 concentrations in soil air are paralleled by the lack of oxygen, the effects of CO 2 could be combined with the effects of soil hypoxia. In response to belowground CO 2 action, shoot processes can be affected, and, moreover, the direct effects of CO 2 on aboveground parts (photosynthesis, transpiration, respiration) can be expected at least in calm periods, when high atmospheric [CO 2 ] is built up, (see Pfanz et al, 2004;Tuba et al, 2003;Badiani et al, 1999).…”

Few studies have investigated the interaction of ultraviolet (UV)-B radiation and CO 2 concentration on plants. We studied the combined effects of UV-B radiation and CO 2 concentration on canola (Brassica napus cv. 46A65) under four growth conditions -ambient CO 2 with UV-B (control), elevated CO 2 with UV-B, ambient CO 2 without UV-B, and elevated CO 2 without UV-B -to determine whether the adverse effects of UV-B are mitigated by elevated CO 2 . Elevated CO 2 significantly increased plant height and seed yield, whereas UV-B decreased them. Elevated CO 2 ameliorated the adverse effects of UV-B in plant height. UV-B did not affect the physical characteristics of leaf but CO 2 did. Certain flower and fruit characteristics were affected negatively by UV-B and positively by CO 2 . UV-B did not affect net photosynthesis, transpiration and stomatal conductance but decreased water use efficiency (WUE). Elevated CO 2 significantly increased net photosynthesis and WUE. Neither UV-B nor CO 2 affected chlorophyll (Chl) fluorescence. UV-B significantly decreased Chl b and increased the ratio of Chl a/b. Elevated CO 2 decreased only the ratio of Chl a/b. UV-B significantly increased UV-absorbing compounds while CO 2 had no effect on them. Both UV-B and CO 2 significantly increased epicuticular wax content. Many significant relationships were found between morphological, physiological, and chemical parameters. This study showed that elevated CO 2 can partially ameliorate some of the adverse effects of UV-B radiation in B. napus.Abbreviations -A N , net CO 2 assimilation; Chl, chlorophyll; E, transpiration; F v /F m , the ratio of variable fluorescence to maximal fluorescence; Gs, stomatal conductance; PS II, Photosystem II; SLW, specific leaf weight; WUE, water use efficiency; Y, yield of quantum efficiency.

“…An analysis of other evidence also shows that relative stimulation of plants grown with low N averaged across several studies appear just as large as those for plants grown with high N [27]. Also the enhanced N use efficiency for biomass (NUEp, ratio of biomass to cumulative N absorption) under elevated CO 2 was reported in rice [28,29] and other species [30], assuming that the same amount of N taken up between elevated and ambient grown plants, greater dry matter will be produced under elevated CO 2 condition. It also revealed the dependence of the CO 2 response on N supply, as identified by a significant CO 2 × N interaction (Table.…”

Future environmental conditions will include elevated concentrations of nitrogen in the soils and elevated concentrations of carbon dioxide in the atmosphere. Increasing CO 2 concentrations are expected to enhance growth of agricultural C 3 crops. However, little is known about what are the consequences of a direct CO 2 fertilization's effect for weeds and much more attention should be given to the combined effect of elevated CO 2 and N supply on plants. In order to study their interactions on both types of plant performance, growth chamber experiments were performed with C 3 crop pea (Pisum sativum L.) and weed white melilot (Melilotus alba Medik.) from the same family grown in a controlled conditions at different CO 2 levels (400 versus 700 and 1400 ppm) combined with three levels (3, 6 and 12 g/m 2 of nitrogen) of fertilization. The photosynthetic rate, transpiration rate, stomatal conductance, water-use-efficienc and dry overground biomass were investigated at the end of an experiment after 10-day duration of treatment. Higher stimulatory effects of elevated 700 and 1400 ppm CO 2 concentrations were on photosynthetic parameters and growth of pea than of melilot. Contrarily, higher stimulatory effects of nitrogen supplies were on investigated parameters of melilot than of pea, but statistically significant only for transpiration rate, stomatal conductance and water-use-efficiency, at ambient and elevated CO 2 levels. The consistent response to both these factors identified in the plants was increased nitrogen use efficiency, who also revealed the dependence of the CO 2 response on N supply, as identified by a significant CO 2 × N interaction. According to these results, we concluded, that under future elevated CO 2 and nitrogen condition, both type of plants will be more efficient in resource use efficiency, but the ability of pea to assimilate additional carbon and the competitive advantage might increase more, compared to melilot.
