Assessing local adaptation vs. plasticity under different resource conditions in seedlings of a dominant boreal tree species

PMCID: 5811874
PMID: 29479406
DOI: 10.1093/aobpla/ply004

[…] ), dry stem biomass (Biomassstem), dry total biomass (Biomasstotal), total root length (TRL; using WinRhizo version 2012b, Regent Instruments Inc., Quebec, QC, Canada) and total leaf area (TLA; using WinSeedle version 2004a, Regent Instruments Inc., Quebec, QC, Canada). Total root length and TLA were measured on fresh tissue. We also investigated allocation patterns in the seedlings by calculating […]


Ecophysiology and Growth of White Spruce Seedlings from Various Seed Sources along a Climatic Gradient Support the Need for Assisted Migration

Front Plant Sci
PMCID: 5766665
PMID: 29358942
DOI: 10.3389/fpls.2017.02214

[…] The projected surface area of the needles, as well as their length (mm) and width (mm), were measured using the WinSeedle (Version 2007 Pro. Regent Instruments, Québec, Canada) image analysis software. The needles were then dried at 63°C for 3 days and subsequently weighed. The specific leaf area (SLA) correspo […]


Thermal acclimation of photosynthesis and respiration of southern and northern white spruce seed sources tested along a regional climatic gradient indicates limited potential to cope with temperature warming

Ann Bot
PMCID: 5838847
PMID: 29300870
DOI: 10.1093/aob/mcx174

[…] Following the measurements of gas exchange, the shoots were carefully removed from the cuvette, harvested, placed in plastic bags and refrigerated (−20 °C). Projected needle area was measured using WinSeedle (Version 2007 Pro, Regent Instruments, Québec, Canada). Samples were then oven-dried for 72 h at 56 °C and their dry mass was determined. Specific leaf area (SLA) was calculated as the ratio […]


Reconstructing grassland fire history using sedimentary charcoal: Considering count, size and shape

PLoS One
PMCID: 5407794
PMID: 28448597
DOI: 10.1371/journal.pone.0176445

[…] and the sample was sieved with a 60μm mesh. The area of each charcoal particle, the length and width of each particle, and the total count of charcoal pieces per sample were measured with the program WinSeedle (Regent Instrument Inc., regular version 2016).The area of charcoal has been demonstrated to limit biases on the interpretation of charcoal count, due to possible fragmentation of charcoal p […]


Variation in short term and long term responses of photosynthesis and isoprenoid mediated photoprotection to soil water availability in four Douglas fir provenances

Sci Rep
PMCID: 5223217
PMID: 28071755
DOI: 10.1038/srep40145

[…] −2 s−1 light intensity after steady state of photosynthetic CO2 gas exchange was achieved, typically after 10–12 min. After the measurement, the light exposed needle surface area was determined using WinSeedle software and scanner (Regents Instruments Inc., Québec, Canada). The rate of photosynthetic gas exchange was expressed per projected needle area exposed to the light. Intrinsic water-use eff […]


Morpho Physiological Variation of White Spruce Seedlings from Various Seed Sources and Implications for Deployment under Climate Change

Front Plant Sci
PMCID: 5042969
PMID: 27746795
DOI: 10.3389/fpls.2016.01450

[…] gas exchange measurements, the branch was excised and immersed in liquid nitrogen. All of the needles were then detached from the branch for calculation of the projected foliar surface area using the WinSeedle software (Regent Instrument Inc., Québec, QC, Canada). […]
