“…De Temmerman et al (2007) found reduced root yield and altered quality of Beta vulgaris (sugar yield, alpha-amino-N, Na and K contents) from O 3 exposure. Intraspecific differences were observed in yield responses of rice (Ariyaphanphitak et al 2005), wheat (Wahid 2006b;Singh and Agrawal 2009) barley (Wahid 2006a), bean (Flowers et al 2007), potato (Piikki et al 2004) and cotton (Zouzoulas et al 2009 Middleton et al (1953) reported first that O 3 induced injury in pinto bean was reduced when aqueous solution of manganese (maneb) or zinc ethylenebis dithiocarbamate (zineb) was sprayed prior to O 3 fumigation. When sprayed onto poinsettia plants, the fungicides benomyl and diphenylamine (DPA) reduced O 3 injury .…”

Urbanization, industrialization and unsustainable utilization of natural resources have made tropospheric ozone (03) one of the world's most significant air pollutants. Past studies reveal that 0 3 is a phytotoxic air pollutant that causes or enhances food insecurity across the globe. Plant sensitivity, tolerance and resistance to 0 3 involve a wide array of responses that range from growth to the physiological, biochemical and molecular. Although plants have an array of defense systems to combat oxidative stress from 0 3 exposure, they still suffer sizable yield reductions. In recent years, the ground-level 0 3 concentrations to which crop plants have been exposed have caused yield loses that are economically damaging. Several types of chemicals have been applied or used to mitigate the effects produced by 0 3 on plants. These include agrochemicals (fungicides, insecticides, plant growth regulators), natural antioxidants, and others. Such treatments have been effective to one degree to another, in ameliorating Or generated stress in plants. Ethylene diurea (EDU) has been the most effective protectant used and has also served as a monitoring agent for assessing plant yield losses from 0 3 exposure. In this review, we summarize the data on how EDU has been used, the treatment methods tested, and application doses found to be both protective and toxic in plants. We have also summarized data that address the nature and modes of action (biophysical and biochemical) of EDU. In general, the literature discloses that EDU is effective in reducing ozone damage to plants, and indicates that EDU should be more widely used on 0 3 sensitive plants as a tool for biomonitoring of 0 3 concentrations. Biomonitoring studies that utilize EDU are very useful for rural and remote areas and in developing countries where 0 3 monitoring is constrained from unavailability of electricity. The mechanism(s) by which EDU prevents 0 3 toxicity in plants is still not completely known. EDU possesses great utility for screening plant sensitivity under field conditions in areas that experience high 0 3 concentrations, because EDU prevents 0 3 toxicity only in 0 3 sensitive plants. Ozone-resistant plants do not respond positively to EDU applications. However, EDU application dose and frequency must be standardized before it can be effectively and widely used for screening 0 3 sensitivity in plants. EDU acts primarily by enhancing biochemical plant defense and delaying Or induced senescence, thereby reducing chlorophyll loss, and maintaining physiological efficiency and primary metabolites; these actions enhance growth, biomass and yield of plants. We believe that future studies are needed to better address the EDU dose response relationship for many plant species, and to screen for new cultivars that can resist 0 3 stress. Although some research on the physiological and biochemical mechanisms of action of EDU have been performed, the new 'omics' tools have not been utilized to evaluate EDUs mechanism of action. Such data are needed, as is gene exp...

“…Negative but not always significant correlations between plant growth parameters and cumulative ozone concentrations were noted in both cultivars at both exposure sites. Some investigations have found that ozone affects plants by reducing leaf area and plant growth (Agrawal et al, 1993;Saitanis and Karandinos, 2002;Morgan et al, 2003;Zouzoulas et al, 2009). The reduction of leaf area might be connected with higher stomatal density which would lead to higher ozone uptake by leaves and intensified detoxification (Pääkonen et al, 1995;Hetherington and Woodward, 2003).…”

“…The several measured parameters generally have shown similar results: ozone affected plant growth, leading to yield reduction. The observed changes in plant morphology include reduced leaf size in tree species (Dizengremel, 2001;Oksanen, 2003;Riikonen et al, 2004;Riikonen et al, 2010), field mustard (Kleier et al, 1998) and Pima cotton (Grantz and Young, 1995); reduced leaf area and plant height in cotton (Zouzoulas et al, 2009) and tobacco (Saitanis and Karandinos, 2002); decreased leaf area ratio and specific leaf area in soybean (Morgan et al, 2003); and reduction of plant height in cucumber (Agrawal et al, 1993) and chickpea (Welfare et al, 2002). These results come mainly from experiments in controlled or semi-controlled conditions.…”

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.

“…On the scale of 100 years, the increasing trends of tropospheric ozone are qualitatively in agreement with emissions trends of precursors. This has led to the increase in the tropospheric ozone level becoming one of the most crucial environmental problems needing to be solved in the coming decades due to its adverse effects, particularly on vegetation (Finlayson-Pits and Pitts 1997;Ishii et al, 2004;Ishii et al, 2007;Shan and Yin, 2008;Soleimanzadeh et al, 2010;Zouzoulas and Koutroubas, 2009). Hourly mean ozone recorded by the European Monitoring and Evaluation Programme (EMEP) rural ozone monitoring network, rarely approach zero and typically are 2-5 ppb in relatively clean air masses which have had little influence from human activity (Hjellbrekke and Solberg, 2005;Azzi and Duc, 2008).…”

“…Although there is a good agreement regarding a rise in background levels over the past century, in recent decades divergent trends in tropospheric ozone have been observed over different regions of the globe, especially in the north hemisphere (Vingarzan 2004;Zouzoulas and Koutroubas, 2009). Several researchers have demonstrated through data, the existence of a correlation between seasonal trends in the level of ozone concentrations are the local surroundings of various monitoring stations (Adeeb and Shooter 2004;Duenas et al, 2004;Feng et al, 2005;Lee et al, 2009;Piikki and Klingberg, 2009;Azmi et al, 2010).…”

Problem statement:Variations of ozone (O 3 ) concentrations in the Eastern Coastal Region of the Malaysia peninsula were investigated using data obtained from the Malaysian Department of the Environment. The aim of this study was to determine the monthly and seasonal variations of ozone concentrations at all monitoring sites. This study deals with the air quality data recorded at four air quality monitoring stations in the East Coast of the Malaysian peninsula over a ten year period (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). Approach: We focused on the usage of S-Plus and SPSS to analyze this data. The S-Plus programming was used to impute missing data and SPSS was used to obtain the variations of ozone and also to clarify the relationship between stations. Results: Over the entire 10 year period (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006), the trend in annual baseline ozone generally increased each year for all the four monitoring sites. There was also a seasonal variability in the measured ozone levels with high concentrations during the southwest monsoon and the northeast monsoon season, producing a significant increase in the amplitude of the seasonal cycle. The results also shown that the highest ozone concentrations were recorded at the Bukit Kuang air monitoring station (S1), with a daily mean value of 19 ppb followed by the Indera Mahkota air monitoring station (S2). The concentration of ozone recorded at Kota Bharu (S3) and Kuala Terengganu (S4), two stations located in the city centre, was found to be lower than the values recorded at Bukit Kuang and Indera Mahkota. The correlation between O 3 and NO is high at Kuala Terengganu (S4) (ρ = -0.579), whilst the relationship between O 3 and NO 2 are high (ρ = -0.397) at Indera Mahkota (S2). Conclusion: The concentration of ozone in the East Coast of Malaysian peninsula depends on the concentration of NOx and seasonal meteorological factors.
