Responses of a tropical tree species to ozone: visible leaf injury, growth, and lipid peroxidation

Abstract: The Brazilian native tree species Astronium graveolens was indicated as sensitive to ozone in a fumigation experiment. Thus, the objective of this study was to evaluate how sensitive A. graveolens is to ozone under realistic conditions in the field. Eighteen saplings were exposed to ozone in a contaminated area and in a greenhouse with filtered air during two exposure periods of approximately 63 days each (March-May 2012 and September-October 2012). Leaf injury was analyzed by means of its incidence and severi… Show more

“…Comparisons between pre- and post-exposure to O 3 based on a GC/MS analysis, shows the dynamics of LCFA composition in elevated O 3 . Previously, the relationship was studied by evaluating malondialdehyde (MDA), an indicator of lipid peroxidation (Calatayud et al 2003 ; Cassimiro and Moraes 2016 ). However, the actual changes to compounds by O 3 have not, as yet, been well researched.…”

“…Both plant growth and production as well as plant species biodiversity are significantly disturbed under elevated O 3 conditions, which portends a significant threat to global food security (e.g. Schimidhuber & Tubiello 2007;Feng, Kobayashi, & Ainsworth 2008;Furlan et al 2008;Wittig, Ainsworth, Naidu, Karnosky, & Long 2009;Ainsworth, Yendrek, Sitch, Collins, & Emberson 2012;Wilkinson, Mills, Illidge, & Davies 2012;Agathokleous, Saitanis, & Koike 2015;Cassimiro & Moraes 2016;Freire et al 2017). It is estimated that the average current background concentration of O 3 in the northern hemisphere is around 20-50 nmol mol À1 and O 3 concentrations are predicted to increase due to expected rise in O 3 precursor emissions in the future, implying even greater effects of tropospheric O 3 on global climate change and on atmospheric oxidative status by the end of this century (Vingarzan 2004;Fowler et al 2008).…”
