“…Samples were analyzed using a portable RQflex 10 reflectometer (MERCK KGaA, Darmstadt, Germany). This equipment is a reliable to measure peroxides concentration (Chutteang et al, 2012). These environmental control procedures are almost identical to those of Chen et al (2005;.…”

“…Chutteang et al (2012) reported that the monthly average level of hydrogen peroxide in Tokyo, Japan and Chiang Mai, Thailand from 2009-2011 was about 2 ppbv and the maximum concentrations reach up to 6 ppbv in summer. Therefore, the trend of the atmospheric concentration of gas-phase peroxides has been gradually increasing , Chutteang et al, 2012. Atmospheric peroxides cause denaturing enzymes, poorly controlled stomata aperture, and oxidizing cell membrane by their strong oxidizing agents and high water-soluble properties (Zhou and Lee, 1992;O'Sullivan et al, 1996;Jiang et al, 2004).…”

Air pollutant concentrations such as ozone (O 3 ) and peroxides have been increasing in the world, and may cause many negative impacts on crop production. The objectives of the present study are to investigate the effects of peroxides and O 3 on visible foliar injury and physiological responses, and to compare the sensitivities among two Thai rice cultivars, RD 31 and Chainat 1, and two Japanese rice cultivars, Nipponbare and Nourin 52, under exposure to single O 3 and combined O 3 and peroxides. Four treatment plots were prepared, namely control plot (O 3 2-3 ppbv and free peroxides), O 3 50 ppbv plot and free peroxides, O 3 50 ppbv and peroxides 3 ppbv plot and O 3 50 ppbv and peroxides 5 ppbv plot. The results showed that combined O 3 and several ppbv peroxides plots caused severe damage on visible leaf injury, increase in Malondialdehyde (MDA) concentration, and decrease in total chlorophyll content and a net photosynthetic rate much higher than single O 3 plot. According to the O 3 dose response analysis, we found that, in combined O 3 (50 ppbv) and peroxides (3 ppbv and 5 ppbv) exposure, in case of visible foliar injury, Chainat 1 was seriously damaged rice cultivar while Nipponbare was a less damaged rice cultivar.

“…The concentrations of gas-phase H 2 O 2 are found in ranges of 0.02 to 6 ppbv in Japan. (Sakugawa et al, 1990;Takami et al, 2003;Chutteang et al, 2012). The peroxide concentrations were in the order of several ppbv in Nagano Prefecture, Japan (Chen et al, 2008).…”

“…In fact, combined O 3 and peroxides are much more harmful to some vegetables and other plants than single O 3 (Chen et al, 2005;Chen et al, 2010). Recent investigations showed that peroxides concentrations have been increasing (Chen et al, 2008;Chutteang et al, 2012). Terry et al (1995) suggested that peroxides can damage DNA, lipids, proteins, and plasma membrane that may impact productivity by a reduced photosynthetic rate, inhibited translocation and declined biomass.…”

Crop response to future air pollution stress is important information for crop production in the future. Ozone (O 3) and peroxides are recognized as significantly damaging air pollutants to plants. Therefore, the present research aimed to investigate the single and combined effects of O 3 and peroxides on leaf injury and physiological responses, and to compare the soybean cultivar sensitivities under exposure to single O 3 and combined O 3 and peroxides. Two Japanese soybean cultivars, Tachinagaha (TC), and Chamame (CM) and two Thai soybeans, A75 and Sorjor 5 (SJ5) were selected as plant materials. Four treatment plots were set up, including a control plot (C plot: free O 3 and peroxides), O 3 50 ppbv (O plot), O 3 50 ppbv and peroxides 2-3 ppbv (OP1 plot) and O 3 50 ppbv and peroxides 4-5 ppbv (OP2 plot). We found that combined O 3 and several ppbv peroxides (OP2 plot) caused more severe damage than the OP1 plot and single O 3 (O plot) to leaf injury, chlorophyll content and photosynthetic rate, and reduced total dry weight and pod dry weight. In combined O 3 and peroxides exposure, SJ5 showed the most sensitive cultivar in leaf injury, photosynthetic rate, biomass and pod dry weight, while CM showed less sensitivity for photosynthetic rate and pod dry weight.
