“…Maximal A values, near 17 mol m 2 s 1 , obtained for P. canariensis needles, were within the range given for tree species and were very high compared with the majority of coniferous species (Larcher 1995). Admittedly, they were near to the values obtained for some pine species adapted to habitats of similar latitude, like P. densiflora from Japan (Kume et al 2000), P. ponderosa from California and Oregon (Zhang et al 1997;Hubbard et al 1999) and P. elliottii from Florida (Byres et al 1992). This suggests that photosynthetic rates reached by species adapted to sub-tropical regions, generally are higher than that of taxa adapted to temperate regions.…”

Gas exchange characteristics and chlorophyll fluorescence of the Canarian endemic pine (Pinus canariensis) were measured during the day for a year in a field stand on Tenerife, Canary Islands, Spain. Diurnal tendencies of gas exchange were variable depending on ambient conditions. In general they paralleled photosynthetic photon flux density with only one peak at midday, except on summer days with high air vapour pressure deficit (VPD), when needles exhibited a severe midday depression of CO 2 assimilation rate (A), in parallel with a reduction of stomatal conductance (g s ). The internal CO 2 concentration tendencies during the day suggest that stomatal closure was the main cause of the midday depression of photosynthesis. Chlorophyll fluorescence data corroborate this assertion, with the parameter F v /F m reaching high values throughout day and year. P. canariensis living in the sub-tropic exhibited high values of A (maximal A value of 17 mol m 2 s 1 ) and high optimal needle temperature for photosynthesis (25C) which were at the upper limit of the values given for conifers and similar only to data obtained for some pine species adapted to habitats at similar latitudes. g s was reduced to half when VPD attained 40 mbar, allowing this pine to have high A/g s values during high evaporative demand conditions.

“…Kohno and Matsumura showed that P. densiflora is one of the most sensitive coniferous trees to O 3 stress (CRIEPI 2001), unlike Japanese black pine, P. thunbergii Parl., which is tolerant to O 3 stress (Matsumura 2001). However, the causes of physiological disorders of needles were suggested to be NO x -related substances and not O 3 (Kume et al 2000(Kume et al , 2001b.…”

“…The net photosynthesis (Pn), stomatal conductance (gl), and intercellular CO 2 concentration near saturating irradiance in declining forest stands were shown to be lower than those in nondeclining stands (about 30%, 50%, and 20% lower, respectively). Atmospheric NO 2 concentrations are negatively correlated with needle longevity and positively with needle ethylene emission (Kume et al 2000). It is generally thought that the indirect toxic effect of NO 2 via O 3 formation is much more damaging than the direct effect of atmospheric NO 2 (Heber et al 1995).…”

Seasonal changes in needle water content and needle ABA concentration of Japanese red pine, Pinus densiflora, in declining forests on Mt. Gokurakuji, Hiroshima prefecture, Japan

To evaluate the effects of air pollution on the decline of Pinus densiflora forests, various research has been conducted around Mt. Gokurakuji (34 degrees 23'N, 132 degrees 19'E, 693 m a.s.l.) north of the Seto Inland Sea, west Japan. To investigate the mechanisms responsible for decreases in photosynthesis (Pn) and stomatal conductance (gl), delta13C of needles and seasonal changes in the water content (WC) and abscisic acid concentration (ABA) of needles were measured in various stands. The delta13C values were less negative in declining stands and younger needles. ABA and WC were not correlated with each other. WC decreased consistently with needle age while the ABA showed a minimum in August and a smaller content in older needles. Monthly precipitation and the daily maximum vapor pressure were not correlated with ABA and WC. In declining stands, WC and ABA tended to be higher and lower, respectively, than in nondeclining stands. These results suggest that the trees in declining stands received less water stress than those in nondeclining stands and the differences in gl and delta13C are not caused by the difference in water stress. The possibilities of the effects of air pollution and the infection of pine-wood nematode on the physiological decline on the pine needles are discussed.

Acid precipitation may inhibit tree growth via either disruption of leaf chlorophyll induced by high H + concentration or changes in soil chemistry (specifically Al toxicity) coupled with pH changes (Shan et al, 1997;Shan, 1998).…”

BACKGROUND: Soil acidification, which is known to be one of the reasons of forest decline, is associated with decreases in exchangeable Ca and increases in Al concentration, leading to low Ca/Al ratio in soil solution. As tree rings are datable archives of environmental changes, Ca/Al ratios of annual growth ring may show decreasing pattern in accordance with the progress of soil acidification. This study was conducted to investigate Ca/Al pattern of Pinus densiflora tree ring in an attempt to test its usefulness
