“…In the review by Ainsworth (2008), for rice, the number of grains was reduced by 20% at a mean O 3 concentration of 62 ppb. Shi et al (2009) reported that the number of florets per panicle was significantly reduced, but individual grain mass was only slightly reduced for sensitive rice cultivars under elevated O 3 exposure in fully open-air field conditions. Grain weight per plant is one of the yield components most critical to crop yield.…”

“…Because our results were expressed as the relative yield and their component values under O 3 treatment compared with those under CF treatment using the same-designed OTCs, the OTC effects were avoided to some degree. O 3 -FACE (Ozone-free air control enrichment) experiments have been carried out in USA, Europe and China (Shi et al, 2009), but unfortunately, it is difficult to derive doseeresponse functions from these data because only one treatment and one control are deployed in most FACE experiments.…”

“…Feng et al (2003) studied the effects of elevated O 3 concentration on potplanted wheat and rice in North China. Shi et al (2009) and Zhu et al (2011) investigated the effects of O 3 on rice and winter wheat yields, respectively, for four cultivars under open-air field conditions. However, it is not clear whether the doseeresponse relationships based on single season investigations or only two treatments are reliable predictors of long-term crop losses under elevated O 3 concentrations.…”

a b s t r a c tThe effects of a continuing rise of ambient ozone on crop yield will seriously threaten food security in China. In the Yangtze River Delta, a rapidly developing and seriously air polluted region in China, innovative open-top chambers have been established to fumigate winter wheat and rice in situ with elevated O 3 . Five years of study have shown that the yields of wheat and rice decreased with increasing O 3 concentration. There were significant relationships between the relative yield and AOT40 (accumulated hourly O 3 concentration over 40 ppb) for both winter wheat and rice. Winter wheat was more sensitive to O 3 than rice. O 3 -induced yield declines were attributed primarily to 1000-grain weight and harvest index for winter wheat, and attributed primarily to grain number per panicle and harvest index for rice. Control of ambient O 3 pollution and breeding of O 3 tolerant crops are urgent to guarantee food security in China.

“…Over the last decade similar studies are now increasingly being conducted in Asia . The Free Air Concentration Enrichment approach has recently been used as an experimental method to assess impacts on crops (soybean in the US; [Morgan et al, 2006]; rice in China: [Shi et al, 2009]) forest trees (Aspen, Maple and birch) in Wisconsin, US: [Karnosky et al, 2003]; mature beech stands in Bavaria, Germany: ) and grasslands (alpine semi-natural grassland in the Swiss Alps ). These methods have advantages of being closer to field conditions but are limited in their ability to define impacts at or below ambient pollutant concentrations and in defining dose-response relationships which are necessary for regional scale risk assessments.…”

“…The economic loss of crop yield due to ozone for four major commodities has been estimated at 14-26 billion USD per year (van Dingenen et al, 2009). Yield reduction has been noted in many crop plant species, such as wheat (Rai et al, 2007;Feng et al, 2008), potato (Vandermeiren et al, 2005), rice (Shi et al, 2009) and cotton (Hassan and Tewfik, 2006).…”

The study assessed the effect of cumulative tropospheric ozone on the morphology of an ozone-sensitive (Bel W3) and an ozone-resistant (Bel B) tobacco cultivar, and two petunia cultivars (Mirage, White Cascade). The plants were exposed at two sites differing in tropospheric ozone level for two months during the 2008 growing season. Similar sets of plants were cultivated in control conditions. Morphological parameters of the plants were measured every week during the experiment. The correlation between the recorded results and the cumulative concentrations of tropospheric ozone measured at the two exposure sites was estimated. The ozone-sensitive tobacco cultivar showed increased visible damage after four weeks of the experiment, although ozone was relatively low during the preceding weeks, possibly confirming the cumulative effect of ozone on the plant response. The ozone-resistant tobacco cultivar showed higher mean plant growth and leaf growth than the ozone-sensitive one throughout the experimental period, but at the exposure sites the ozone-sensitive cultivar showed plant growth similar to or higher than the controls, especially at the forest site where ozone concentrations were higher. This suggests a plant defense against reduction of leaf assimilation area (i.e., against leaf necrosis). Petunia cv. Mirage showed lower growth at the control site and had fewer flowers than White Cascade at all sites. White Cascade had more flowers than Mirage in the last week of the experiment at the forest site where tropospheric ozone was higher. Its mean growth was higher at the forest site than at the other exposure site.K Ke ey y w wo or rd ds s: : Tobacco, petunia, morphology, tropospheric ozone.
