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 ...

The effects that ground speed and obstacle height have upon microsite creation by the Bracke scarifier and upon the seeding characteristics of the integral seeder were studied. The study was conducted in a former gravel ...

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 ...

This study looks at the influence of the ectomycorrhizal fungus Hebeloma longicaudum to form associations and impact growth of jack pine seedlings under simulated drought conditions. Four treatment groups of jack pine ...

The objectives of this investigation were 1) to examine the duration and pattern of jack pine growth response to urea fertilization and low thinning, and 2) to examine methods commonly used in the measurement of ...

Pollen pool heterogeneity, which violates an assumption of the mixed-mating model, is one of the major problems facing population geneticists concerned with measuring plant mating systems. In the present study, isozyme ...

The influence of "acid rain" (watering with tap water acidified to pH 3.0 ) and drought on jack pine seedlings and balsam poplar cuttings growing in two different soil types was studied in a short-term greenhouse experiment. ...

Understanding the responses of trees, ectomycorrhizal fungi (ECM) and their association to climate change can be challenging due to their interactions with multiple environmental factors. The combined impacts of elevated ...

To understand the pattern of adaptive variation of jack pine in north central Ontario better, short-term provenance tests were established. Seed was collected from 64 sites to the east and west of Lake Nipigon and grown ...

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 ...
