STUDY ON IMPROVING THE GROWTH QUALITY OF PLANTED SEEDLING OF PINUS koraiensis IN INITIAL STAGE

引用

Journal of Northeast Forestry University 1995年第3期6卷 79-83页

作者：李传荣李萍 Northeast Forestry University P.R. China

Each link in initial process of artificial regeneration of Pinus koraiensis in clear cutting site was researched. The seedling recovery processes after transplantation. the affecting seedlings survival factors in different time, and the characters of seedling growth were analyzed. Results of this study suggest that the root recovery of Korean pine secdlings after transplanting is the key link in the artificial regeneration management. The synthetically management was proposed on basis of seedling root recovery process.

Science China Earth Sciences 2007年第4期50卷 613-619页

The long-term effect of elevated CO2 concentrations on needle dark respiration of two coniferous spe- cies—Pinus koraiensis and Pinus sylvestriformis on the Changbai Mountain was investigated using open-top chambers. P. koraiensis and P. sylvestriformis were exposed to 700, 500 μmol·mol-1 CO2 and ambient CO2 (approx. 350 μmol·mol-1) for four growing seasons. Needle dark respiration was meas- ured during the second, third and fourth growing seasons’ exposure to elevated CO2. The results showed that needle dark respiration rate increased for P. koraiensis and P. sylvestriformis grown at elevated CO2 concentrations during the second growing season, could be attributed to the change of carbohydrate and/or nitrogen content of needles. Needle dark respiration of P. koraiensis was stimu- lated and that of P. sylvestriformis was inhibited by elevated CO2 concentrations during the third growing season. Different response of the two tree species to elevated CO2 mainly resulted from the difference in the growth rate. Elevated CO2 concentrations inhibited needle dark respiration of both P. koraiensis and P. sylvestriformis during the fourth growing season. There was consistent trend be- tween the short-term effect and the long-term effect of elevated CO2 on needle dark respiration in P. sylvestriformis during the third growing season by changing measurement CO2 concentrations. How- ever, the short-term effect was different from the long-term effect for P. koraiensis. Response of dark respiration of P. koraiensis and P. sylvestriformis to elevated CO2 concentrations was related to the treatment time of CO2 and the stage of growth and development of plant. The change of dark respiration for the two tree species was determined by the direct effect of CO2 and long-term acclimation. The prediction of the long-term response of needle dark respiration to elevated CO2 concentration based on the short-term response is in dispute.

Mode of pollen spread in clonal seed orchard of Pinus koraiensis

引用

Journal of Biophysical Chemistry 2010年第1期1卷 33-39页

作者： Fu-Juan Feng Xin Sui Min-Min Chen Dan Zhao Hi-Jie Han Mai-He Li Institute of Applied Ecology Chinese Academy of Sciences Shenyang China Institute of Applied Ecology Chinese Academy of Sciences Shenyang China Northeast Forest University Harbin China Swiss Federal Research Institute WSL Birmensdorf Switzerland

The patterns of effective pollen dispersal and the relationships between pollen dispersal and genetic composition in Pinus koraiensis are still unclear. Hence, we investigated the mode of pollen dispersal of P. koraiensis in a clonal seed orchard in Lushuihe Forestry Bureau, Jilin Province, using SSR molecular markers tech-nique and the method of maximum likelihood. A total of 13 pairs of nuclear microsatellites po-lymorphic primers were used in the paternity analysis. We analyzed 100 progenies and 150 paternities. A total of 56 alleles were detected in 13 loci with 3-6 alleles (4.3 alleles in average) in a single locus. The primers of SsrPt_ctg7170 and SsrPt_ctg5333 had the maximum (6) and the minimum (3) alleles, respectively. The averaged values of observed heterozygosity, expected heterozygosity and polymorphism information content of experimental groups were 0.648, 0.601 and 0.533, respectively. The mating dis-tance of P. koraiensis followed an approximately normal distribution. The most effective pollen for the female parent came from male parent trees 15-45 m away with an average mating dis-tance of 32.60 m and the longest of 67.88 m. The pollen source of offspring was not random but greatly affected by the wind direction during the pollination season of P. koraiensis. These re-sults have important implications for seed or-chard design to improve the genetic quality of seeds and seed production.

Anti-inflammatory effects of natural volatile organic compounds from Pinus koraiensis and Larix kaempferi in mouse model

Natural volatile organic compounds(VOCs) extracted from conifers such as P. koraiensis and L. kaempferi have long been studied for their anti-oxidant, anti-proliferative, and anti-inflammatory effects. To evaluate the anti-inflammatory effects of VOCs from P. koraiensis and L. kaempferi, lipopolysaccharide(LPS) was administered to generate a mouse model for inflammation by the nasal route to the lungs and intraperitoneally to the whole body. VOCs of P. koraiensis and L. kaempferi were exposed to the mice by standardized wood panels with closed system. Increased levels of serum IgE and PGE2 were observed after exposure to dexamethasone and VOCs. We further determined the expression levels of inflammatory cytokine mRNA in the LPS-induced inflammation model by the reverse transcription quantitative polymerase chain reaction. Furthermore, the levels of cyclooxygenase-2, tumor necrosis factor-α, interleukin-1β, and interleukin-13 were determined in peripheral blood mononuclear cells. Those inflammatory cytokines and the key enzyme for inflammation cyclooxygenase-2 expression in PBMCs were strongly reversed by dexamethasone and VOCs. Lung tissues after nasal LPS exposure showed increased cytokine mRNA expressions which were suppressed by treatment with dexamethasone and VOCs. Furthermore, the damage induced by LPS was attenuated by dexamethasone and VOCs. In conclusion, the results from the present study indicate that VOCs of P. koraiensis and L. kaempferi have a therapeutic potential in the treatment or prevention of local and systemic inflammation due to their immunosuppressive effects.

林业科技通讯 2019年第9期 8-10页

作者：卢正茂辽宁省森林经营研究所

以辽东山区人工阔叶红松混交林为研究对象,以红松(Pinus koraiensis)纯林为对照,调查分析了红松-白桦(Betula platyphylla Suk.)、红松-色赤杨(Alnus tinctoria)、红松-水曲柳(Fraxinus mandshurica)、红松-刺楸(Kalopanax septemlobus)、红松-紫椴(Tilia amurensis)人工阔叶混交林的乔木层、灌木层、草本层及总生物量。结果表明:人工阔叶红松混交林总生物量的大小与混交林中与红松伴生的阔叶树种生长速度有关,如果伴生树种生长速度快于同龄红松生长,林地总生物量明显大于红松纯林;反之小于红松纯林。并且红松纯林内灌木层、草本层生物量低于各类型的阔叶红松混交林。
