Competition trials of Pinus banksiana and Populus tremuloides under a range of proportions and densities
(1986)
This study was the -first study designed specifically to
analyse the competitive effects of density and species mixture
for both Pinus banksiana and Populus tremuloides
seedlings during the initial stages of growth and ...
Within and between-species competition and individual tree growth in a young jack pine-aspen stand
(1986)
The competitive relationship between jack pine (Finns banksiana Lamb.) and trembling aspen (Populus tremuloides Michx.) was studied in an 8-year-old mixed stand in North Central Ontario, Canada. During the summer of 1984, ...
Approach to predict nutrient status and growth response of fertilized jack pine by foliar diagnosis
(1979)
A factorial experiment testing N, P and K fertilizers, and a
series of simpler, two-treatment (control and NPK) fertilizer trials
were established in a range of jack pine stands to determine the
application of a foliar ...
Effects of Photoperiod, Soil Moisture and Soil Temperature on the Northward Migration Potential of Jack Pine under the Scenario of Doubled Atmospheric CO2 Concentration
(2016)
Climate envelope models predict that boreal trees can potentially migrate northward by as much as 10º by 2100 as a consequence of the predicted climate change associated with the doubling of atmospheric CO2 concentration, ...
Soil-site relations for jack pine in the Thunder Bay area
(1986)
Site index of natural jack pine (Pinus banksiana Lamb.) in the Thunder Bay area was related to features of soil and topography using multiple regression analyses. Site index (SI, height of jack pine trees at 50 years from ...
Establishment and early growth of jack pine (Pinus banksiana Lamb.) in Acton Township Ontario
(1986)
The objective of this study was to investigate the effect of different site
preparation methods on the establishment and growth of jack pine (Pinus banksiana Lamb.) on two different soil types. These sites were either ...
An assessment of the utility of an unmanned aerial vehicle for measuring tree heights in a jack pine provenance trial
(2020)
This independent study is an assessment of the utility of an unmanned
aerial vehicle (UAV) for measuring the heights of jack pine (Pinus banksiana)
trees in a provenance trial. An electronic hypsometer, the Haglöf Vertex ...
Effective root growth potential of jack pine (Pinus banksiana Lamb.) container stock
(1989)
The effective root growth potential (RGP) of both potted and
outplanted jack pine seedlings grown in Lannen-Sokeri FH-408 paperpots
and Can-Am #2 Multipots was measured on three test dates during the
summers of 1986 and ...
Jack pine fitness under current and future climate
(2020)
Climate change has the potential to drastically alter the functioning of Canada’s forests and the species that live there. The importance of understanding patterns of adaptive variation in relation to climate is imperative ...
