“…Plants can metabolize SO 2 taken up in gaseous form through their stomata. Many studies have investigated plant damage caused by SO 2 , including physiological responses and growth (e.g., photosynthesis, stomatal functions, water-use traits) (Chung et al 2011;Furukawa 1991;Haworth et al 2012;Ikeda et al 1992;Natori and Totsuka 1988;Swanepoel et al 2007). At high SO 2 concentrations, plants decrease the photosynthetic uptake of CO 2 and increase respiration.…”

We used a physiological approach to investigate the effect of sulfur dioxide (SO2) on Alnus sieboldiana Matsum. (A. sieboldiana) and symbiotic Frankia spp. in Miyakejima Island, which was devastated by volcanic action in July of 2000. In April of 2008, three study sites were chosen in the forest of Miyakejima Island, and were categorized as high, medium, or low in relation to their sulfur dioxide concentration (volcanic gas). Nine A. sieboldiana trees were selected from naturally regenerated forest at each site. The higher the SO2 concentration at the study site, the lower was the photosynthetic rate and the maximum photochemical efficiency of PSII (Fv/Fm) of A. sieboldiana and its apparent quantum yield. The acetylene reduction rate of the Frankia spp. symbiotic with A. sieboldiana was significantly less at the high SO2 concentration (p<0.05). The nitrogen concentration in their leaves remained high, however. There was no significant difference in the chlorophyll concentration (Chl a + b) in leaves from the three sites. The photosynthetic nitrogen use efficiency decreased significantly in sites with a high SO2 concentration, however. As a result, A. sieboldiana regenerated at the sites with high or medium SO2 concentration underwent approximately 50–70 % less growth than at the site with a low SO2 concentration.

“…Why the evergreen conifers initially recovered faster than the deciduous angiosperms is unknown. Plant species can develop tolerance to pollutants that are known to affect photosynthesis [44,45]. The greater tolerance in evergreen conifers could be a result of the different fire strategies, in which gamble oak, rocky mountain maple, and aspen employ a survival strategy of overstory morality followed by asexual regeneration at some later time [34][35][36].…”

Smoke from forest fires can persist in the environment for weeks and while there is a substantial amount of literature examining the effects of smoke exposure on seed germination, the effects of smoke on leaf function are nearly uninvestigated. The objective of this study was to compare growth and primary and secondary metabolic responses of deciduous angiosperm and evergreen conifer tree species to short smoke exposure. Twenty minutes of smoke exposure resulted in a greater than 50% reduction in photosynthetic capacity in five of the six species we examined. Impairment of photosynthesis in response to smoke was a function of reductions in stomatal conductance and biochemical limitations. In general, deciduous angiosperm species showed a greater sensitivity than evergreen conifers. While there were significant decreases in photosynthesis and stomatal conductance, smoke had no significant effect on growth or secondary defense compound production in any of the tree species examined.

“…Even if the stomata are closed, SO 2 can enter the leaf by overcoming the cuticular resistance (Larcher 2003). The solubility factor of SO 2 is about 40 times higher than that of CO 2 , enabling SO 2 to dissolve in the apoplast and form sulphite (SO 3 2( ) and hydrogen sulphite (HSO 3 ( ), which then enter the cell (Larcher 2003: Swanepoel et al 2007). These ions can be metabolized there to sulphates, which are nontoxic or less toxic and may be stored or used up in plant nutrition.…”

“…Gaseous pollutants inhibit photosynthesis possibly by (i) damaging electron transport between photosystems, (ii) reducing phosphoenol pyruvate (PEP) activity, (iii) inhibiting RUBP and/or (iv) competing with NADPH for nitrite reduction and carbon assimilation in the chloroplasts (Rennenberg and Herschbach 1996;Ishibishi et al 1997). However, in the case of Augea capensis, even high concentrations of SO 2 could cause inhibitory effects on photosynthesis, that were too fully reversible only when fumigation was done in the dark, possibly pointing to diurnal differences in cellular capacity for SO 2 detoxification (Swanepoel et al 2007). …”

Behavioral responses of leaves and vascular cambium ofProsopis cineraria(L.) Druce to different regimes of coal-smoke pollution

The foliar and cambial responses of Prosopis cineraria to five different coal-smoke regimes in Delhi, India, were studied using the monthly collections of leaves and cambial blocks as well as the data on SO 2 , NO 2 and particulate concentrations from each of the five study sites. Coal-smoke inhibited pigment concentration, NR activity and sugar content and promoted stomatal index and the nitrate and sulfur contents. Stomatal conductance was low, leading to a drop in the net photosynthetic rate. Cambial activity started quite late and the annual increment of wood was reduced despite a prolonged active phase, possibly due to a distinctly retarded rate of cambial cell division. Vessel proportion in the wood increased but the size of vessel elements and fibers decreased. Such studies may help in identifying trees suitable for cultivation in the pollutionaffected areas.
