“…However, we also confirmed that Ca 2? and pectic polysaccharides are removed from plant cell walls in current-year needles of fir through acid fog exposure in a previous study (Shigihara et al 2008). Ca 2?…”

“…are leached from plant foliar tissue through acid wet deposition such as rain, fog, and dew (Olson et al 1981;Igawa et al 2002a;Chiwa et al 2003). In general, the leached amount of base cations increased with decreasing pH of wet deposition (Igawa et al 2002a;Shigihara et al 2008).…”

“…Recently, we reported that a dimeric rhamnogalacturonan II-borate complex (dRG-II-B) that exists in the cell wall as pectic polysaccharide was converted to monomeric RG-II (mRG-II) by leaching of Ca 2? and boron by acid fog exposure (Shigihara et al 2008).…”

The decline of virgin fir (Abies firma) forest at Mt. Oyama has been reported. Related field observations suggest that high acidity fog is linked with its decline. However, cedar (Cryptomeria japonica) in the same area shows no symptoms of decline. For assessing effects of acid fog on membrane-bound calcium (mCa) of the leaf mesophyll cells, 9-year-old seedlings of fir (Abies firma) and 8-year-old seedlings of cedar (Cryptomeria japonica) were exposed twice a week to simulated acid fog (SAF at pH 3 with pH 5 as control) for 2 h per day in a chamber during May-December 2007 (except August). Current and 1-year-old needles were collected from seedlings and analyzed at 1-month intervals. For current-year needles of fir, mCa levels in cells exposed to SAF at pH 3 were significantly lower than in cells exposed to pH 5, especially during September 2007-March 2008. In contrast, it is noteworthy that mCa levels of cedar were maintained as virtually constant irrespective of SAF acidity, indicating that fir is more sensitive to acid fog than is cedar. Based on these results, mCa loss by acid fog might also be caused in the declining virgin fir forest at Mt. Oyama.

“…The decreased amount of epicuticular wax enhances the possibility of H ? diffusing to the leaf interior and leaching nutrients from the leaf (Tyree et al 1991;Shigihara et al 2008b). Chronic O 3 exposure to beech saplings had no effect on the total amount of epicuticular wax.…”

The effects of simulated acid fog (SAF) and ozone (O 3 ) stress on the growth and physiology of beech (Fagus crenata) saplings were investigated. Three-year-old beech saplings were exposed to SAFs of pH 3 and pH 5 (control) during May 2007 to July 2008. In each SAF treatment group, half of the saplings were exposed to 60 ppb of O 3 during September 2007 to July 2008. In comparison to the control saplings, those from the pH 3 treatment had lower total plant biomasses, epicuticular wax amounts, Ca 2? concentrations in their leaves, and lower starch concentrations in their leaves and roots. The effect of O 3 was significant only for the starch concentration in the roots, but the O 3 exposure also negatively affected the growth and physiology of beech saplings. Results show that acid fog exerts various severe effects, and that both chronic acid fog and O 3 exposure suppressed the physiological functions of beech saplings.
