“…Foliar injury was increased, but pod numbers and biomass were reduced when peak levels were included. Similar results were demonstrated in closed outdoor chambers in Germany for spring wheat (Meyer et al, 1997(Meyer et al, , 2000, potato (S. tuberosum) (Köllner and Krause, 2000), and rape (B. napus) (Köllner and Krause, 2003 Using our complete diurnal exposure regime, we have been able to demonstrate that it produced more relevant results than using a single constant O 3 exposure regime. Greater yield losses were identified with CF100D than with CF100.…”

“…Closed outdoor exposure chambers were used in a series of experiments in Germany. Greatest effects on growth and yield were found at higher rather than intermediate peak levels for alfalfa (Hogsett et al, 1985), spring wheat (Triticum aestivum L.) (Meyer et al, 1997(Meyer et al, , 2000, bean (P. vulgaris L.) (Musselman et al, 1994), potato (Solanum tuberosum L.) (Köllner and Krause, 2000), birch (B. pendula cv.

Most available exposureeresponse relationships for assessing crop loss due to elevated ozone (O 3 ) have been established using data from chamber and open-top chamber experiments, using a simulated constant O 3 concentration exposure (square wave), which is not consistent with the diurnal variation of O 3 concentration that occurs in nature. We investigated the response of oilseed rape (Brassica napus L.) to O 3 as affected by two exposure regimes: one with a diurnal variation (CF100D) and another with a constant concentration (CF100). Although the two exposure regimes have the same mean O 3 concentration and accumulated O 3 concentration above 40 ppb (AOT40), our results show that O 3 at CF100D reduced biomass and number of pods/plant more than O 3 at CF100. Both O 3 exposures resulted in larger seed weights/ 100 pods compared to CF. Numbers of seeds/100 pods were reduced by CF100, while numbers of seeds/100 pods in the CF100D chambers were comparable to those in CF. Our results suggest that chamber experiments that use a constant O 3 exposure may underestimate O 3 effects on biomass and yields.

“…In the present study, less biomass was allocated to roots under O 3 stress, as shown by the increased shoot-to-root ratio (Figure 2). This finding is consistent with the results of Hoshika et al (2013) and Nouchi et al (1991) in crops and Köllner and Krause (2000) in trees. The influence of elevated O 3 on biomass allocation can be explained by the Optimal Partitioning Theory, which suggests that plants should allocate more biomass to the organ that requires the most limited resource (McCarthy and Enquist, 2007).…”

There has been little investigation into the effects of ozone (O 3) on flowering plants around settlements, even though such plants are known to be threatened by elevated O 3. In this study, we used open-top chambers to assess the ornamental value of marigolds (Tagetes erecta Linn.) and four petunia (Petunia hybrid Vilm.) varieties in terms of their growth and physiological responses to elevated O 3. The aboveground biomass decreased by 7.4% in marigolds and by 19.4-23.6% in four varieties of petunia in response to

“…Probably, O 3 used for 1 h per day for five days is not sufficient for a larger loss of pigments. It has been shown that chronic ozone exposures can cause a significant decline in pigment content, but acute treatment may not be sufficient to induce any modification in the constitutive levels of chlorophylls [35][36][37]. Also, there was found no effect of the concentration and time of O 3 use on the level of total phenols analyzed by the Folin assay.…”

Tropospheric ozone forms in photochemical reactions or by refuse burning and combustion of exhaust gases from engines, and during some industrial processes. The mean ambient ozone concentration doubled during the last century, and in many urban areas has reached the phytotoxic level. In the present study, there was determined the effect of ozone fumigation on levels of individual flavonoids, chlorophylls, carotenoids and total phenols in the cotyledons of four common buckwheat cultivars (Hruszowska, Panda, Kora and Red Corolla). Six-day-old buckwheat seedlings were grown in controlled conditions and treated with an elevated dose of ozone (391 µg · m -3 ) during 5 days for 1 h each day. After the experiment, the cotyledons of the seedlings were analysed for individual flavonoids, chlorophylls, carotenoids and total phenols. Shoot elongation was also measured. Individual types of flavonoids in buckwheat cotyledons were found to respond to an elevated ozone dose in various ways. The response was also dependent on the cultivar evaluated. In the cotyledons of ozonized buckwheat seedlings, contents of C-glucosides of luteolin and apigenin decreased or did not change depending on the cultivar examined. In the case of flavonols, the contents of quercetin-3-O-rhamnosyl-galactoside and rutin (quercetin-3-O-rhamnosyl-glucoside) were markedly reduced in most cultivars. O3 had no effect on the level of anthocyanins and chlorophylls but it decreased carotenoids, and tended to inhibit buckwheat growth. In conclusion, a thesis can be formulated that, due to high reduction in important flavonoids, an elevated level of ambient ozone decreases the nutritional value of common buckwheat seedlings.
