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 کاملEcosystem carbon stocks in Pinus palustris forests
Longleaf pine (Pinus palustris Mill.) restoration in the southeastern United States offers opportunities for carbon (C) sequestration. Ecosystem C stocks are not well understood in longleaf pine forests, which are typically of low density and maintained by prescribed fire. The objectives of this research were to develop allometric equations for aboveand below-ground biomass and quantify ecosyst...
متن کاملRoot distribution of Pinus banksiana (Lamb.) from natural and planted stands
In Quebec, the law requires forestry companies to look after the regeneration of the forests they exploit. The natural cycle of jack pine (Pinus banksiana Lamb.) is related to fire, which allows opening of the cones and dispersal of the seeds. But after harvesting, the exploited sectors are normally replanted. It has been shown that the current methods of seedling production and planting cause ...
