Modeling Jack Pine (Pinus banksiana) Foliage Density Distribution
The vertical distribution of foliage biomass is important because it is associated with photosynthesis and is closely related to some wood quality attributes such as branch diameter and sapwood content. In this article we propose a model to predict foliage biomass distribution within the crown for jack pine trees in Eastern Canada. This model has two parts. The first one distinguishes the propo...
متن کاملDiterpenoids from the buds of Pinus banksiana Lamb.
Three new diterpenoids, namely 7α-hydroxyabieta-8,11,13,15-tetraen-18-oic acid, 7β,15,18-trihydroxyabieta-8,11,13-triene, 13,15-dihydroxypodocarpa-8,11,13-triene, and 12 other known compounds were isolated from buds of Pinus banksiana Lamb. All these compounds, except for 7-oxodehydroabietinol, were isolated for the first time from this plant. Their structures were elucidated by detailed spectr...
متن کاملA mitochondrial DNA minisatellite reveals the postglacial history of jack pine (Pinus banksiana), a broad-range North American conifer.
Jack pine (Pinus banksiana Lamb.) is a broadly distributed North American conifer and its current range was covered by the Laurentian ice sheet during the last glacial maximum. To infer about the history and postglacial colonization of this boreal species, range-wide genetic variation was assessed using a new and highly variable minisatellite-like marker of the mitochondrial genome. Among the 5...
متن کاملDifferential effects of plant ontogeny and damage type on phloem and foliage monoterpenes in jack pine (Pinus banksiana).
Coniferous trees have both constitutive and inducible defences that deter or kill herbivores and pathogens. We investigated constitutive and induced monoterpene responses of jack pine (Pinus banksiana Lamb.) to a number of damage types: a fungal associate of the mountain pine beetle (Dendroctonus ponderosae Hopkins), Grosmannia clavigera (Robinson-Jeffrey & R.W. Davidson); two phytohormones, me...
متن کاملDevelopment and growth of the aerial part of Pinus banksiana Lamb. from natural and planted stands
In Quebec, jack pine (Pinus banksiana Lamb.) is an important commercial species, used principally for timber wood and pulp. The natural ecology of jack pine is related to fire, which allow opening of the cones and dispersal of seeds (Burns and Honkala 1990). The exploitation of jack pine stands disturbs this cycle and the regeneration remains low after harvesting and plantation must be done to ...
