“…Results have shown that a single acid rain treatment (pH 1.8) to P. vulgaris can reduce gas exchange, the maximum carboxylating efficiency and photochemical quenching (Velikova et al 1999). The results found in the present experiment agree with those reported in other studies, indicating that photosynthesis is generally unaffected by simulated acid rain (Shan et al 1996;Anderson et al 1997;Momen et al 1997). However, the threshold of acid rain injury varies to a considerable extent, depending on plant species (Velikova et al 1999).…”

G. W. 2004. Impact of simulated acid rain on photochemistry, morphology, and yield of the wild blueberry (Vaccinium angustifolium Ait.). Can. J. Plant Sci. 84: 877-880. The effects of simulated acid rain (SAR) on the photochemistry, net photosynthesis (Pn), morphological damage, and crop yield were studied on Vaccinium angustifolium Ait. Although there was an 8% decrease in fluorescence origin with the pH 1.5 SAR treatment when compared to the control, no effects on the quantum efficiency of photosystem II (PSII) photochemistry, Pn, leaf and berry wax deposition were detected. There was no SAR effect on crop yield or the physiological components studied. Les auteurs se sont intéressés aux effets d'une pluie acide artificielle sur la photochimie, la photosynthèse nette, les dommages morphologiques et le rendement de Vaccinium angustifolium Ait. Bien que la pluie acide artificielle (pH 1.5) réduise la fluorescence de 8 % comparativement aux plants témoin, le traitement n'a aucune incidence sur l'efficacité quantique des processus photochimiques du PSII, la photosynthèse nette ni le dépôt de cire sur les feuilles et les baies. La pluie acide artificielle n'agit pas sur le rendement ni sur les paramètres physiologiques examinés.

“…Water use efficiency (WUE) is an important agronomic character that also decreased slightly at the highest OTC stress (Table 3). Combined with related assays showing that damage to plant tissues may reduce WUE (Shan et al 1996;Reich et al 1985) and the marked reduction in enzyme activities in the leaves (Table 2), it can be inferred that OTC might injure the functional tissues in the leaves. Leaf ultrastructure was observed using transmission electron microscopy (TEM) to demonstrate this assumption.…”

Water spinach (Ipomoea aquatic Forsk.) was selected to investigate the effects of oxytetracycline (OTC) on the toxicity of soil contaminated by long-term sewage irrigation. After acute toxicity test in petri dish at nine different OTC-spiked levels for 48 h, the germination rate was found to be generally inhibited in all treatments treated with OTC but the root elongation and activities of several antioxidant enzymes, superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) were either forward or backward stimulated to varying extent. During a 60-day sub-chronic toxicity test by means of a pot experiment, activities of SOD, POD and CAT in both the leaf and root tissue at 25 mg OTC per kg soil (dry weight) and in root tissue at 1 mg OTC per kg soil (dry weight) were significantly different than those in other treatments, which also indicated the higher sensitivity of the root. The foliar photosynthetic rate, stomatal conductance and transpiration rate were all gradually inhibited in spite of elevated water use efficiency under the pressure of the different OTC concentrations, which were highly significant different at 10 mg OTC per kg soil (dry weight). Indices of soil microbial diversity at 4 mg OTC kg −1 soil were significantly different from those of the control, indicating the potential adverse effects of OTC to soil microorganisms. The results suggest that the introduction of OTC could damage both plants and soil microorganisms, and during sub-chronic incubation, the sensitivity of different indices generally followed the order of root tissue antioxidant enzyme activities, soil microbial diversity indices, leaf photosynthesis-related index and leaf tissue enzyme antioxidant activities. In addition, the application of livestock and poultry manure containing pollutants like OTC in farmland soil, especially if the soil has been contaminated before, should be taken more seriously in the context of the current pursuit of increased agricultural production.

“…Several O 3 effects on roots have been reported, including the impact in their architecture (Vollsnes et al, 2010) and density (Hoshika et al, 2013b), their tips formation (Vollsnes et al, 2010), their monosaccharide and starch concentrations (Braun et al, 2004;Thomas et al, 2005), and their elongation rates (Vollsnes et al, 2010). An important variables often observed to be influenced by O 3 is the shoot:root ratio (Franzaring et al, 2000;Landolt et al, 2000;Samuelson, 1994;Sanz et al, 2005;Shan et al, 1995Shan et al, , 1996. Most of the reports suggest that roots are suppressed at a higher degree than shoots, which may consequently lead to their inability to support the aboveground parts.…”

Ambient ozone (O 3 ) poses a growing threat to the global ecosystems due to its high phytotoxicity: it may possibly reduce the productivity of wild plants as well as the species' biodiversity. Asia hosts a remarkable number of wild plant species; thus, studies dealing with Asian species' responses to O 3 are of great importance. We have retrieved, from scientific databases, 195 papers dealing with the response of 473 wild plants species to O 3 . Some species we characterize as "ozonophobic" have been reported to be negatively affected by O 3 , even at O 3 levels lower than the AOT40 threshold. This review revealed the lack of research dealing with the effects of O 3 on endangered or threatened plant species, as well as on important medical plants. Such research is needed not only from an ecological point of view or in terms of biodiversity value, but also from an anthropocentric point of view. Several wild species carry unique substances that are used in medicines for healing human diseases or in agro-industry for the production of agrochemicals, thus securing human welfare.
