“…It is also possible that increased monoterpene emission at elevated temperature could result in increased consumption of the monoterpene pools in the needles but this does not explain the unaltered monoterpene concentration in the C needles or the strongly increased content in 2000 that was observed in our study. The effects of elevated temperature on the rate of photosynthesis and respiration are contrary to the effects of elevated CO 2 : photosynthesis is inhibited and additionally the metabolic rates increase with increasing temperature resulting in increased consumption of assimilates via respiration (Zha et al 2001;Rowland-Bamford et al 1996;Farrar and Williams 1991). This may result in a smaller allocation of carbon into secondary compounds.…”

The aim of this study was to evaluate the longterm effects of elevated CO 2 concentration (doubling of ambient CO 2 concentration) and temperature (2-6°C elevation) on the concentration and content of secondary compounds in the needles of Scots pine (Pinus sylvestris L.) saplings grown in closed-top environmental chambers. The chamber treatments included (1) ambient temperature and CO 2 , (2) ambient temperature and elevated CO 2 , (3) elevated temperature and ambient CO 2 , and (4) elevated temperature and elevated CO 2 . The needle sampling and analyses of monoterpenes, HPLC-phenolics and condensed tannins in current-and 1-year-old needles were made in two consecutive years. The results showed that the effects of elevation of CO 2 and temperature were greatest on the monoterpene concentration in the needles while the concentration of HPLC-phenolics remained almost unaffected by the changed growing conditions. Most of the observed decrease in monoterpene concentration was caused by the CO 2 enrichment while the effect of elevated temperature alone was not as significant. The accumulation of condensed tannins tended to increase due to the elevation of CO 2 alone compensating the reduced carbon allocation to monoterpenes. Overall, the responses of the concentrations of secondary compounds to the elevation of CO 2 and temperature are variable and depend strongly on the properties and characteristics of each compound as well as on the interrelation between the production of these compounds and the primary production of trees.

“…The increase of soluble sugars was also observed following chronic exposure stated by Miller et al, 10 . In all patterns over the years, high concentration of air pollutants (CO 2 , NO 2 ) treatments increased the soluble, the insoluble and the total carbohydrate levels in the soybean leaves was reported by Rowland-Bamford et al, 11 . In most cases, decreases in the concentration of sugars were found which agreed with the previous work by researchers 12 .…”

The present investigation is the impact of air pollution on biochemical parameters of fifteen common tree species growing in different locations of Virudhunagar, Tamilnadu, India. The biochemical parameters taken into considerations were soluble protein content and total carbohydrate content of leaves. Variation in carbohydrate response to pollution stress may reflect difference in pollutants concentrations. Also, pollution tolerance has been associated with several biochemical characteristics such as higher concentrations of reducing sugars. It is evident from this research that the flow of the carbohydrates from the source to the sinks was affected by increased levels of studied gases. In addition, found a decrease in protein concentration under air pollution. Plant species differ in their response to air pollution. The results indicate that protein and carbohydrate content of leaves show considerable variation with the increase of intensity of air pollutants concentration.

“…The photosynthetic responses of higher plants to CO 2 enrichment, including acclimation, have mainly been studied during vegetative growth (Webber et al, 1994;Koch, 1996;Wolfe et al, 1998), and CO 2 enrichment has been reported to increase the total concentration of non-structural carbohydrates in leaf blades, leaf sheaths, and culms (Rowland-Bamford et al, 1996). The enhancement of growth and yield by CO 2 enrichment has been reported for many plant species, including rice (Baker et al, 1990a;Baker and Allen, 1993;Rowland-Bamford et al, 1996).…”

However, the effect of CO 2 enrichment on the translocation of photosynthates has only been examined during shortterm CO 2 enrichment (Grodzinski et al, 1998).…”
