Ameliorating Effects of Leaf Water Extract of Three Aromatic Plant Species on Ozone-Polluted Snap Bean (Phaseolus vulgaris L. ‘Jiangjunyoudou’)

Ameliorating Effects of Leaf Water Extract of Three Aromatic Plant Species on Ozone-Polluted Snap... Ozone (O3) is one of the major pollutants in near-surface air. In order to protect sensitive plants from O3 pollution, many kinds of protectants including synthetic ones, were assessed in previous studies. Although they have certain protective effects, some of them are not environment-friendly. In the present study, leaf water extracts of aromatic plants [Plectranthus hadiensis var. tomentosus (PHT), Pelargonium hortorum (PHB), Tagetes patula (TP)] were compared for mitigating the damages caused by O3 (150 ppb for 3 days, 8 h day−1) on snap bean (Phaseolus vulgaris ‘Jiangjunyoudou’). Our results showed that O3 fumigation impaired plasma membrane, decreased chlorophyll content, increased contents of malondialdehyde and superoxide anion, inhibited photosynthesis, and caused visible injury. Leaf water extracts of PHT, PHB or TP ameliorated the negative effects of O3. Among them, extract of PHT showed the greatest potential to alleviate the O3-caused injury, followed by PHB and TP. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Bulletin of Environmental Contamination and Toxicology Springer Journals

Abstract

Ozone (O3) is one of the major pollutants in near-surface air. In order to protect sensitive plants from O3 pollution, many kinds of protectants including synthetic ones, were assessed in previous studies. Although they have certain protective effects, some of them are not environment-friendly. In the present study, leaf water extracts of aromatic plants [Plectranthus hadiensis var. tomentosus (PHT), Pelargonium hortorum (PHB), Tagetes patula (TP)] were compared for mitigating the damages caused by O3 (150 ppb for 3 days, 8 h day−1) on snap bean (Phaseolus vulgaris ‘Jiangjunyoudou’). Our results showed that O3 fumigation impaired plasma membrane, decreased chlorophyll content, increased contents of malondialdehyde and superoxide anion, inhibited photosynthesis, and caused visible injury. Leaf water extracts of PHT, PHB or TP ameliorated the negative effects of O3. Among them, extract of PHT showed the greatest potential to alleviate the O3-caused injury, followed by PHB and TP.
