“…Increase of photosynthesis under elevated CO 2 has previously been reported for other C 3 crop species (Cure and Acock, 1986;Sicher and Bunce, 1999;Vandermeiren et al, 2002) but only few studies were focussed on differences between leaves of the same plant (Osborne et al, 1998;Turnbull et al, 1998;Backhausen and Scheibe, 1999). We observed the highest increase of photosynthesis rate in middle-aged and old leaves of plants under longterm exposure to elevated CO 2 .…”

“…Elevated CO 2 induces stomatal closure through increased C i levels (Morison and Gifford 1983), thereby limiting the O 3 invasion inside the leaf mesophyll and reducing O 3 injury (Unthworth and Hogsett 1996, Olszyk and Wise 1997, Vandermeiren et al 2002, CardosoVilhena et al 2004. In our experiment, both elevated O 3 and elevated CO 2 reduced the g s , which decreased even further when these two gases were combined (Fig.…”

“…So far, the effects of O 3 and CO 2 on the photosynthesis, growth, and yield of important economic plants such as wheat (Rao et al 1995, Rudorff et al 1996, Mulholland et al 1997, Donnelly et al 2000, CardosoVilhena et al 2004, Feng et al 2007, potato (Lawson et al 2001, Vandermeiren et al 2002, soybean (Bernacchi et al 2006), and peanut (Booker et al 2007) have been studied. However, the underlying mechanisms of the interaction between O 3 and CO 2 still remain uncertain (Unthworth and Hogsett 1996, Lee 2000, Morita and Tanaka 2002, Vandermeiren et al 2002, Cardoso-Vilhena et al 2004, Weigel 2004.…”

Therefore, we wanted to know how detrimental O 3 and promotive CO 2 interact and thereby affect the photosynthesis and production processes of rice, because observations of the combined effect of O 3 and elevated CO 2 on this Asian staple food crop are few and limited only to its growth response (Olszyk andWise 1997, Ookoshi andImai 1998).…”

Tropospheric ozone (O 3 ) decreases photosynthesis, growth, and yield of crop plants, while elevated carbon dioxide (CO 2 ) has the opposite effect. The net photosynthetic rate (P N ), dark respiration rate (R D ), and ascorbic acid content of rice leaves were examined under combinations of O 3 (0, 0.1, or 0.3 cm 3 m -3 , expressed as O 0 , O 0.1 , O 0.3 , respectively) and CO 2 (400 or 800 cm 3 m -3 , expressed as C 400 or C 800 , respectively). The P N declined immediately after O 3 fumigation, and was larger under O 0.3 than under O 0.1 . When C 800 was combined with the O 3 , P N was unaffected by O 0.1 and there was an approximately 20 % decrease when the rice leaves were exposed to O 0.3 for 3 h. The depression of stomatal conductance (g s ) observed under O 0.1 was accelerated by C 800 , and that under O 0.3 did not change because the decline under O 0.3 was too large. . Excluding the stomatal effect, the mesophyll P N was suppressed only by O 0.3 , but was substantially ameliorated when C 800 was combined. Ozone fumigation boosted the R D value, whereas C 800 suppressed it. An appreciable reduction of ascorbic acid occurred when the leaves were fumigated with O 0.3 , but the reduction was partially ameliorated by C 800 . The degree of visible leaf symptoms coincided with the effect of the interaction between O 3 and CO 2 on P N . The amelioration of O 3 injury by elevated CO 2 was largely attributed to the restriction of O 3 intake by the leaves with stomatal closure, and partly to the maintenance of the scavenge system for reactive oxygen species that entered the leaf mesophyll, as well as the promotion of the P N .

“…Though increases in photosynthesis and growth are typical under elevated vs. current CO 2 for most C 3 species, decreases in tissue nutrient concentrations often occur too, and not just for nitrogen (e.g., Cure and Acock 1986;Sicher and Bunce 1999;Vandermeiren et al 2002;Norby et al 1986;Roberntz and Stockfors 1998;Fangmeier et al 1996;Luomala et al 2005). The increase in biomass under elevated CO 2 is largely attributed to increases in net photosynthesis and nutrient limitation has generally been found to suppress this response (Conroy 1992;McKee and Woodward, 1994;Lloyd and Farquhar, 1996;Stitt and Krapp, 1999).…”

Elevated CO2 affects plant responses to variation in boron availability

Aim Effects of elevated CO 2 on N relations are well studied, but effects on other nutrients, especially micronutrients, are not. We investigated effects of elevated CO 2 on response to variation in boron (B) availability in three unrelated species: seed geranium (Pelargonium x hortorum), barley (Hordeum vulgare), and water fern (Azolla caroliniana). Methods Plants were grown at two levels of CO 2 (370, 700 ppm) and low, medium, and high B. Treatment effects were measured on biomass, net photosynthesis (P n ) and related variables, tissue nutrient concentrations, and B transporter protein BOR1. Results In geranium, there were interactive effects (P< 0.05) of B and CO 2 on leaf, stem, and total plant mass, root:shoot ratio, leaf [B], B uptake rate, root [Zn], and P n . Elevated CO 2 stimulated growth at 45 μM B, but decreased it at 450 μM B and did not affect it at 4.5 μM B. P n was stimulated by elevated CO 2 only at 45 μM B and chlorophyll was enhanced only at 450 μM B. Soluble sugars increased with high CO 2 only at 4.5 and 45 μM B. High CO 2 decreased leaf [B] and B uptake rate, especially at 450 μM B. Though CO 2 and B individually affected the concentration of several other nutrients, B x CO 2 interactions were evident only for Zn in roots, wherein [Zn] decreased under elevated CO 2 . Interactive effects of B and CO 2 on growth were confirmed in (1) barley grown at 0, 30, or 1,000 μM B, wherein growth at high CO 2 was stimulated more at 30 μM B, and (2) Azolla grown at 0, 10, and 1,000 μM B, wherein growth at high CO 2 was stimulated at 0 and 10 μM B. Conclusion Thus, low and high B both may limit growth stimulation under elevated vs. current [CO 2 ], and B deficiency and toxicity, already common, may increase in the future.
