Effects of brassinosteroids on prosperity of Scots pine seedlings
plant hormones seedlings Pinus sylvestris growth biomass production
2015/5/5
We tested the influence of exogenous application of brassinosteroids (BRs) on survival, growth and
biomass production of Scots pine (Pinus sylvestris) seedlings. BRs are natural substances, supposed...
Tree-ring cellulose d18O variability in pine and oak and its potential to reconstruct precipitation and relative humidity in central Japan
tree-ring cellulose d18O pine oak precipitation relative humidity central Japan
2017/4/10
Oxygen isotope ratios (d18O) of tree-ring cellulose in pine (Pinus densiflora) and oak (Quercus serrate and Quercus
variabilis) growing in central Japan from 1970 to 2011 share a common inter-annual ...
Spatial variability of water repellency in pine forest soil
spatial variability water repellency WDPT test infiltration sorptivity
2015/2/3
The variability of water repellency of pine-forest arenic regosols and its influence on infiltration processes were measured in southwest Slovakia. The water drop penetration time (WDPT) tests of soil...
Applying GreenLab Model to Adult Chinese Pine Trees with Topology Simplification
GreenLab Model Adult Chinese Pine Treesh opology Simplification
2011/2/21
This paper applied the functional structural model GreenLab to adult Chinese pine trees (pinus
tabulaeformis Carr.).
No Longer Anchored, Antarctic Ice Stream Surges to Sea--Under-Ice Sub Finds Ridge That May Have Held Back Pine Island Glacier（图）
Antarctic Ice Stream Sea Ice Sub Back Pine Island Glacier
2010/6/22
Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide...
Emissions and ambient distributions of Biogenic Volatile Organic Compounds（BVOC）in a ponderosa pine ecosystem: interpretation of PTR-MS mass spectra
Biogenic Volatile Organic Compounds BVOC ponderosa pine ecosystem PTR-MS mass spectra
2010/2/21
Two proton-transfer-reaction mass spectrometry systems were deployed at the Bio-hydro-atmosphere interactions of Energy, Aerosols, Carbon, H2O, Organics and Nitrogen-Southern Rocky Mountain 2008 field...
Carbonyl sulfide exchange in a temperate loblolly pine forest grown under ambient and elevated CO2
Carbonyl sulfide loblolly pine forest CO2
2010/2/1
Vegetation, soil and ecosystem level carbonyl sulfide (COS) exchange was observed at Duke Forest, a temperate loblolly pine forest, grown under ambient (Ring 1, R1) and elevated (Ring 2, R2) CO2. Duri...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Autumn temperature and carbon balance of a boreal Scots pine forest in Southern Finland
Autumn temperature carbon balance a boreal Scots pine forest Southern Finland
2010/1/21
We analyzed the dynamics of carbon balance components: gross primary production (GPP) and total ecosystem respiration (TER), of a boreal Scots pine forest in Southern Finland. The main focus is on inv...
Eddy covariance methane measurements at a Ponderosa pine plantation in CaliforniaEddy covariance methane measurements at a Ponderosa pine plantation in California
Eddy covariance methane measurements Ponderosa pine plantation California
2009/11/19
Long term methane flux measurements have been mostly performed with plant or soil enclosure techniques on specific components of an ecosystem. New fast response methane analyzers make it possible to u...

New particle formation oxidation direct emissions pine seedlings
2009/11/9
Measurements of particle formation following the gas phase oxidation of volatile organic compounds (VOCs) emitted by Scots pine (Pinus sylvestris L.) seedlings are reported. Particle formation and con...
Estimation of Canopy Reservoir Capacity and Oxygen-18 Fractionation in Throughfall in a Pine Forest
Canopy Reservoir Capacity Oxygen-18 Fractionation Pine Forest
2009/10/27
Amount and oxygen-18 content of rainfall and throughfall have been monitored
in a pine forest in Uppsala during summer 1983. It is found that the free
throughfall coefficient, C, the canopy reservoi...
Simulation of the long-term carbon and nitrogen dynamics in Dutch forest soils under Scots pine
long-term carbon Dutch forest soils nitrogen dynamics Scots pine
2009/6/5
Dynamics of C and N in forest soils in the Nutrient Cycling and Soil Acidification Model (NUCSAM) are described by the transformation and decomposition of three organic matter compartments, litter, fe...
