        Establishment and early growth of jack pine (Pinus banksiana Lamb.) in Acton Township Ontario 

        Sianga, Cassian W. (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 Examination of bark beetles and their associated blue stain fungi on boreal jack pine (Pinus banksiana) and white spruce (Picea glauca) in the Thunder Bay Region 

        Andersen, Steen Peder Korsgaard (2009)
        Blue stain, caused by members of the Ophiostomatales, is of concern to the forest industry because it can quickly devalue timber by penetrating deep into the sapwood and creating dark blue to black staining. These fungi ...

        Genecology of jack pine in north central Ontario 

        Van Niejenhuis, Annette (1995)
        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 ...

        Ground speed : its influence on the direct seeding of jack pine (Pinus banksiana Lamb.) with the Bracke scarifier 

        McNutt, John W. (1993)
        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 ...

        Height, growth and site index of jack pine (Pinus banksiana Lamb) in the Thunder Bay area : a system of site quality evaluation 

        Lenthall, Daniel J. (1986)
        Height growth patterns and site index were studied using stem analyses taken from dominant and codominant trees growing on 109 plots located in mature, natural, fully stocked evenaged stands of jack pine {Pinus banksiana ...

        Interactive effects of elevated CO2 and temperature, nutrition, and ectomycorrhizas on morphological traits and summer shoot formation in jack pine 

        Kielt, Erin (2022)
        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 ...
