“…(2010)). Even though VPD was estimated using air temperature and relative humility in the present study, the correlation coefficient between f VPD and f temp was very small (0.094), which is in agreement with the results reported by Pleijel et al (2002). The Jarvis-type Eq.…”

“…Similar results were also found for winter wheat (Triticum aestivum L.) grown in subtropical China and UK (GonzalezeFernandez et al, 2010). Nevertheless, most European studies found that flux-based doseeresponse relationship provided a higher R 2 value than concentration-based exposure indices in assessing O 3 -induced biomass loss of wheat (T. aestivum L., Danielsson et al, 2003;Pleijel et al, 2004), potato (Solanum tuberosum L., Pleijel et al, 2002Pleijel et al, , 2004, timothy (Phleum pretense, Danielsson et al, 2013), juvenile silver birch (Betula pendula Roth, Uddling et al, 2004), and subterranean clover (Trifolium subterraneum L., cv.

“…It was assumed that there is no strong correlation between f VPD and f temp , even though VPD was estimated based on temperature (Pleijel et al, 2002). These mathematical functions were parameterized using a boundary line technique, which was first introduced by Webb (1972), and has been widely used in plant and soil science models (Bhat and Sujatha, 2013;Blanco-Macías et al, 2010;Lewandowski and Schmidt, 2006;Topp et al, 2013;Vizcayno-Soto and Côte, 2004).…”

a b s t r a c tConcentration-and flux-based O 3 doseeresponse relationships were developed for poplars in China. Stomatal conductance (g s ) of five poplar clones was measured to parameterize a Jarvis-type multiplicative g s model. The maximum g s and other model parameters varied between clones. The strongest relationship between stomatal O 3 flux and total biomass was obtained when phytotoxic ozone dose (POD) was integrated using an uptake rate threshold of 7 nmol m À2 s À1 . The R 2 value was similar between flux-based and concentration-based doseeresponse relationships. Ozone concentrations above 28 e36 nmol mol À1 contributed to reducing the biomass production of poplar. Critical levels of AOT 40 (accumulated O 3 exposure over 40 nmol mol À1 ) and POD 7 in relation to 5% reduction in total biomass for poplar were 12 mmol mol À1 h and 3.8 mmol m À2 , respectively.

“…In Europe, the stomatal diffusive conductance (Gs) model, which is used to estimate the stomatal uptake of O3, includes the accumulated exposure of O3 concentration as a factor influencing the senescence-induced reduction in the Gs through the O3-induced premature leaf senescence (Pleijel et al, 2002;Danielsson et al, 2003). On the other hand, Grulke et al (2007) reported that the calculated foliar O3 flux from the Gs measured in O3-free conditions, overestimates the actual foliar O3 flux as a result of reduction in the Gs by concurrent O3 exposure.…”

To obtain basic information concerning the evaluation of the effects of O3 on the yield of Japanese rice (Oryza sativa L.), we investigated the effects of O3 on the growth, yield and leaf gas exchange rates of rice. Two Japanese cultivars of rice (Koshihikari and Kinuhikari) were grown in plastic boxes filled with flooded Andisol in 9 chambers, and were daily exposed to charcoal-filtered air or O3 at 60 or 100 nl l 1 (ppb) (10:00-17:00) from 30 May to 20 September, 2007. The whole-plant dry mass and grain yield per plant of the two cultivars at the final harvest were significantly reduced by the exposure to O3. The reduction rates of the grain yield by the exposure to O3 at 60 and 100 ppb were 3 and 23 in Koshihikari, respectively, and 18 and 34 in Kinuhikari, respectively. The sensitivity of growth and yield to O3 was not significantly different between Koshihikari and Kinuhikari.The exposure to O3 significantly reduced the panicle number per plant, and the dry mass per panicle and filled grain number per panicle due to the increase in sterility, but did not reduce 1000 grain weight. The O3-induced reduction in the yield of the two cultivars was mainly attributed to that in the whole-plant growth during the early vegetative period and the biomass allocation to panicle during the reproductive period. During the early vegetative period, the exposure to O3 significantly reduced net photosynthetic rate and stomatal diffusive conductance, regardless of the leaf position. Therefore, the O3-induced reduction in the whole-plant growth of the two cultivars during the early vegetative period was mainly due to that in net photosynthetic rate, partially caused by the stomatal closure. Furthermore, the sensitivity to O3 of the yield components, growth parameters and leaf gas exchange rate were not significantly different between Koshihikari and Kinuhikari.

Ozone concentrations are expected to rise in developing countries, potentially reducing crop yield and causing great economic losses. Therefore, an ozone biomonitoring system based on the ratio of the biomass of ozone‐resistant (NC‐R) and ozone‐sensitive (NC‐S) biotypes of white clover (Trifolium repens cv. Regal) is tested over 2 years (2012 and 2013) at four sites with neighboring crop production in the Metropolitan Region of Campinas (MRC), Brazil. The biomass production of both clones is similar at the four sites studied in the MRC, but significant differences are observed between the monthly harvests during the experimental period. Linear regression analyses show contrasting results from the experimental years. During 2012, the biomass of both clones correlated positively with precipitation and relative humidity, and negatively with vapor pressure deficit, particulate matter, nitrogen dioxide, and ozone. During 2013, the biomass production of both clones did not significantly correlate with oscillating environmental conditions. No significant linear regression between the NC‐S/NC‐R biomass ratio and ozone is found in either year. A stepwise backward multilinear method identified nitrogen dioxide and accumulated dose over a threshold of 40 ppb (AOT40) as the main parameters negatively affecting the biomasses of both clones; particulate matter affected only the sensitive clone. This field experiment shows that the current concentrations of ozone may affect sensitive Brazilian crops.
