“…Inconsistent trends are also reported for maximum PSII photochemical efficiency for woody species under high [CO 2 ] (e.g. Jones et al 1995;Faria et al 1996;Scarascia-Mugnozza et al 1996;Hogan et al 1997;Spunda et al 1998). Additionally, antioxidants -another photoprotective mechanism -are reportedly both higher and lower with [CO 2 ] enrichment (Badiani et al 1993;Schwanz et al 1996;Polle et al 1997;Schwanz & Polle 1998).…”

Lifelong exposure to elevated concentrations of atmospheric CO2 may enhance carbon assimilation of trees with unlimited rooting volume and consequently may reduce requirements for photoprotective pigments. In early summer the effects of elevated [CO2] on carboxylation and light utilization of mature Quercus pubescens trees growing under chronic [CO2] enrichment at two CO2 springs and control sites in Italy were examined. Net photosynthesis was enhanced by 36 to 77%. There was no evidence of photosynthetic downregulation early in the growing season when sink demand presumably was greatest. Specifically, maximum assimilation at saturating [CO2], electron transport capacity, and Rubisco content, activity and carboxylation capacity were not significantly different in trees growing at the CO2 springs and their respective control sites. Foliar biochemical content, leaf reflectance index of chlorophyll pigments (NDVI), and photochemical efficiency of PSII (ΔF/Fm′) also were not significantly affected by [CO2] enrichment except that starch content and ΔF/Fm′ tended to be higher at one spring (42 and 15%, respectively). Contrary to expectation, prolonged elevation of [CO2] did not reduce xanthophyll cycle pigment pools or alter mid‐day values of leaf reflectance index of xanthophyll cycle pigments (PRI), despite the enhancement of carbon assimilation. However, both these pigments and PRI were well correlated with electron transport capacity.

“…This phenomenon is termed photosynthetic 'acclimation'. Acclimation is accompanied by alterations in gas exchange characteristics that are indicative of a decreased capacity for carboxylation (Stitt 1991;Sage 1994) and by a decrease of Rubisco activity in tobacco Sicher, Kremer & Rodermel 1994), tomato (Van Oosten, Wilkins & Besford 1994), Arabidopsis (Cheng, Moore & Seeman 1998), Scirpus olneyi (Jacob et al 1995), wheat (Nie et al 1995;Rogers et al 1996b;Sicher & Bunce 1997), barley (Sicher & Bunce 1997), rice (Vu et al 1997), Panicum laxum (Ghannoum et al 1997), loblolly pine (Tissue, Thomas & Strain 1993, 1997, cherry (Atkinson et al (1997), oak (George, Gerant & Dizengremel 1996) and cork oak (Faria et al 1996).

The nitrogen concentration usually decreases in elevated [CO 2 ] (Wong 1979;Hocking & Meyer 1985;Hocking & Meyer 1991a, 1991bColeman et al. 1993;Pettersson, MacDonald & Stadenburg 1993;Rogers et al. 1993;McKee & Woodward 1994;Jacob, Greitner & Drake 1995;Nie et al. 1995;Poorter et al. 1997), indicating that nitrogen uptake lags behind carbohydrate synthesis and growth in elevated [CO 2 ]. The effect of elevated [CO 2 ] on the nitrate uptake rates per unit root weight is rather variable and apparently depends on the nitrogen concentration supplied (Larigauderie, Reynolds & Strain 1994) and the species. Whereas elevated [CO 2 ] increased the rate of nitrate uptake per unit root weight in loblolly pines (Bassirirad et al. 1996) and Prosopis glandulosa (Bassirirad et al. 1997), it did not alter nitrate uptake in Nardus agrostis (Bassirirad et al. 1997), and it decreased nitrate uptake in a mixed field community (Jackson & Reynolds 1996). Although nitrate uptake might be improved in elevated [CO 2 ] because plants possess more roots and exploit a larger soil volume (see, e.g. Stulen & den Hertog 1993;Pettersson et al. 1993;Jackson & Reynolds 1996), the decreased water flow in elevated [CO 2 ] will tend to decrease the root surface concentrations of nitrate (Van Vuuren et al. 1997).The organic nitrogen concentration decreases in elevated [CO 2 ] (Wong 1979;Curtis, Drake & Whigham 1989;Garbutt, Williams & Bazzaz 1990;Coleman et al. 1991;Hocking & Meyer 1991a, 1991bColeman & Bazzaz 1992;Gries, Kimball & Idso 1993;Pettersson et al. 1993;Körner & Miglietta 1994;Pettersson & MacDonald 1994; FerrarioMery et al. 1997;Poorter et al. 1997), indicating that nitrate assimilation fails to keep pace with growth. There is conflicting evidence with respect to the effect of elevated [CO 2 ] on nitrate reductase (NR) activity. Although elevated [CO 2 ] led to a small increase of NR activity in mustard (Maeskaya et al. 1990) and Vigna radiata (Sharma & Sen Gupta 1990), it produced a two-fold decrease of NR activity in wheat (Hocking & Meyer 1991a), maize (Purvis, Peters & Hageman 1974), and a 15-25% decrease in Nicotiana plumbaginifolia (Ferrario-Mery et al. 1997). It also led to a decrease of nitrite reductase activity in lettuce (Besford & Hand 1989). In Plantago major, elevated [CO 2 ] led to a transient increase in NR activity, that was reversed after a few days (Fonseca, Bowsher & Stulen 1997). These reports of a decrease of NR activity in elevated [CO 2 ] are rather surprising, because exogenous sugars lead to increased expression of Nia (Cheng et al. 1992;Vincentz et al. 1993;Krapp et al. 1993;Krapp & Stitt 1995;Morcuende et al. 1998) and post-translational activation of NR (Kaiser & Huber 1994; Huber, Bachman & Huber 1996) in detached leaves. Recently Geiger et al. (1998) showed that although elevated [CO 2 ] does not markedly increase the maximum NR activity in tobacco the diurnal regulation of NR is modified, allowing higher activity in the later part of the light period and during the night.Even less is kno...

“…japonica×Larix kaempferi) and Quercus suber seedlings. This response was not initiated by stomatal closure but mainly by the reduction in the assimilation capacity which increase the total soluble sugars and starch in leaves (Faria et al 1996;Watanabe et al 2011). Excess of carbohydrate remained in the leaf as sugars or starch made leaves heavier per unit area, thus, contributed to an ineffective transformation of photosynthetic carbon gain into new growth (Kirschbaum 2011).…”
