Adaptation of Lodgepole pine (Pinus contorta) provenances to extreme climate events

长期的种源试验可以评估树种不同基因类型的气候-生长关系。这一知识对于减轻气候变化对森林生态系统的影响至关重要。本项目利用一个独特的机会，基于破坏性全树分析，在罗地松种源试验中研究气候生长关系。前男友。响亮。)。通过结合年高度增长、径向生长、年内高分辨率木材密度和碳同位素剖面，这种方法将能够全面评估气候变化对碳汇、木材生产和木材特性的影响。它还将允许确定在不断变化的气候下重新造林所需的具有弹性和生产力的基因类型。

Long-term provenance trials allow assessing climate-growth relationships of different genotypes of a tree species. This knowledge is crucial in efforts to mitigate impacts of climate change on forest ecosystems. This project is taking advantage of a unique opportunity to study climate growth relations based on destructive whole-tree analysis in provenance trials of Lodgepole pine (Pinus contorta Dougl. ex. Loud.). By combining annual height increment, radial growth, intra-annual high resolution wood density and carbon isotope profiles, this approach will allow for a comprehensive assessment of climate change impacts on carbon sequestration, wood production and wood characteristics. It as well will allow identifying resilient and productive genotypes for reforestation in a changing climate.
