We investigated the responses of photon-saturated photosynthesis rate (P sat ) and its simultaneous acclimation of anatomy and nitrogen use patterns of current needles of Korean pine (Pinus koraiensis) seedlings grown under factorial combinations of two nitrogen levels and irradiances. Although N supply resulted in a significant increase of N content in needles under both irradiances, the increase of P sat tended to be suppressed only in shade (S). The significant increase of P sat in full sunlight (O) was associated with the increase of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBPCO) and chlorophyll (Chl) contents. In contrast, small increase of Chl content and no increase of RuBPCO content were found in S (90 % cut of full irradiance), which would result in a small increase of P sat . This result suggests that extra N is stocked in needles under shade for the growth in next season. With N supply, a significant decrease of specific leaf area (SLA) was detected only in O. This decrease of SLA was due to the increase of density of needle. Furthermore, the increase of needle density was not due to the increased number and size of mesophyll cells, but the increased density of each mesophyll cell. Therefore, although SLA changed in O, the change did not involve anatomical adaptation to use increased N effectively, at least observable by light microscopy. Hence, even though the SLA would change, N deposition will improve the photosynthetic capacity of Korean pine seedlings, not through the development of needle anatomy but through improvement of the allocation of N in both irradiances.Additional key words: acclimation; anatomical plasticity; evergreen-species; net photosynthetic rate; nitrogen allocation and deposition; ribulose-1,5-bisphosphate carboxylase/oxygenase; specific leaf area.

“…In each plantation unit, six Korean pine (Pinus koraiensis) seedlings (two-years-old) were planted. The species is characterized by good tolerance in S, slow growth rate, and good tolerance of soil acidification (Choi et al 2006). We set two different irradiances, O (full sunlight) and S in each unit.…”

“…Presence of lower chlorinated congeners in this study indicated a decline of PCB concentrations in atmospheric air samples, which would ultimately lead to less deposition of these compounds in this region. The current PCB concentrations were either comparable or lower than the available studies from Croatia (Romanic and Krauthacker 2006), Sweden (Kylin and Sjodin 2003), Finland (Sinkkonen et al 1997), UK (Sinkkonen et al 1997), Ireland (Tremolada et al 1996), Poland (Wyrzykowska et al 2006), China (Chen et al 2006), Australia (Tausz et al 2005), Korea (Choi et al 2006), Spain (Grimalt and van Drooge 2006), Japan (Wyrzykowska et al 2006;Hanari et al 2004a, b), Germany (Kylin et al 1994), Sweden (Kylin et al 1996) and USA ). The direction bound deposition of PCBs from the Aroclor 1268 discharge location showed mixed trend (Fig.…”

Deposition of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were measured in Loblolly pine needles (Pinus taeda) collected in and around a Linden Chemicals and Plastics (LCP) Superfund Site at Brunswick, Georgia, USA. For the comparison, foliage of eastern red cedar (Juniperus virginiana) was also collected to monitor contaminant levels. This study revealed that concentrations of OCPs, PCBs and PBDEs ranged from 0.75-10, 3.4-15 to 0.05-3, ng/g wet wt, respectively in both plant species. Total OCPs concentrations in pine needles decreased from 10 to 2.3 ng/g; and total PCBs decreased from 28 to 9.3 ng/g between 1997 and 2006. To our knowledge, this is the first report on PBDEs concentrations in pine needles and red cedar foliage samples from the Superfund Site at Brunswick, Georgia, USA.

To evaluate the effect of ectomycorrhizal colonization on growth and physiological activity of Larix kaempferi seedlings grown under soil acidification, we grew L. kaempferi seedlings with three types of ectomycorrhizae for 180 days in acidified brown forest soil derived from granite. The soil had been treated with an acid solution (0 (control), 10, 30, 60, and 90 mmol H + kg -1 ). The watersoluble concentrations of Ca, Mg, K, Al, and Mn increased with increasing amounts of H + added to the soil. Ectomycorrhizal development significantly increased in soil treated with 10 and 30 mmol H + kg -1 but was significantly reduced in soil treated with 60 and 90 mmol H + kg -1 . The concentrations of Al and Mn in needles or roots increased with increasing H + added to the soil. The total N in seedlings significantly increased with increasing H + in soil and colonization with ectomycorrhiza. The maximum net photosynthetic rate at light and CO 2 saturation (P max ) was greater in soil treated with 10 mmol H + kg -1 than in controls, and was less is soils treated with greater than with 30 mmol H + kg -1 , especially with 60 and 90 mmol H + kg -1 . However, colonization with ectomycorrhiza significantly reduced the concentration of Al and Mn in needles or roots and increased the values of P max and total dry mass (TDM). The relative TDM of L. kaempferi seedlings was approximately 40% at a (BC, base cation)/Al ratio of 1.0. However, ectomycorrhizal seedlings had a 100-120% greater TDM at a BC/Al ratio of 1.0 than non-ectomycorrhizal seedlings, even though the acid treatment reduced their overall growth.
