A cost-effective climate change adaptation strategy for the forestry sector is to move seed sources more northern and higher elevation planting sites as part of ongoing reforestation programs. This meant match locally adapted populations with anticipated environments, but adaptive traits do not always show population differences suitable mitigate impacts. For white spruce, drought tolerance a critical trait prevent mortality productivity losses. Here, we use 40-year-old provenance experiment...
Abstract Background Genomic prediction (GP) and genome-wide association (GWA) analyses are currently being employed to accelerate breeding cycles identify alleles or genomic regions of complex traits in forest trees species. Here, 1490 interior lodgepole pine ( Pinus contorta Dougl. ex. Loud. var. latifolia Engelm) from four open-pollinated progeny trials were genotyped with 25,099 SNPs, phenotyped for 15 growth, wood quality, pest resistance, drought tolerance, defense chemical...
The differential stomatal regulation of transpiration among plant species in response to water deficit is not fully understood, although several hydraulic traits have been reported influence it. This knowledge gap partly due a lack direct and concomitant experimental data on transpiration, conductance, traits. We measured sap flux density (Js), conductance (gs), different five crop species. Our aim was contribute establishing the causal relationship between consumption its using trait-based...
Abstract Understanding local adaptation of tree populations to climate allows the development assisted migration guidelines as a tool for forest managers address change. Here, we study relationship among climate, wide range physiological traits, and field performance selected white spruce provenances originating from throughout species range. Tree height, survival, cold hardiness, hydraulic, wood anatomical traits were measured in 32‐year‐old common garden trial, located center Provenance...
ABSTRACT Drought tolerance of tree species is a concern in the context climate change, and ring analyses can be used to assess past growth response(s), drought events. In current study, we applied this approach 1281 individuals with known pedigree long‐term genetic test plantations lodgepole pine western Canada. We assessed resistance, resilience, recovery metrics, analyzed their causal relationships susceptibility disease through structural equation modeling. found that trees low short‐term...
ABSTRACT Crop plants, including fruit trees, are particularly vulnerable to water scarcity because past selection prioritized productivity over drought resistance, making it challenging maintain with minimal use in the context of climate change. This study aims determine which trait combination 10 tree species influences their and carbon use, goal understanding adaptability scarcity. The results showed that stress traits (turgor loss point, TLP; vulnerability index, VI), a carbon‐related...
Tree improvement programs often focus on improving productivity-related traits; however, under present climate change scenarios, change-related (adaptive) traits should also be incorporated into such programs. Therefore, quantifying the genetic variation and correlations among productivity adaptability traits, importance of genotype by environment interactions, including defense compounds involved in biotic abiotic resistance, is essential for selecting parents production resilient...
Xylem anomalies that are caused by unusual climate events have long been used to aid cross-dating in tree ring research. Here, we analyzed a range of xylem 39-year-old common garden experiment white spruce (Picea glauca [Moench] Voss) central Alberta, Canada, designed investigate local adaptation. We extracted wood cores from trees representing 24 provenances covering much the species across Canadian boreal forest. Using double stain and light microscopy analysis, four their causes could be...
Abstract The environment could alter growth and resistance tradeoffs in plants by affecting the ratio of resource allocation to various competing traits. Yet, how why functional change over time space is poorly understood particularly long-lived conifer species. By establishing four common-garden test sites for five lodgepole pine populations western Canada, combined with genomic sequencing, we revealed decoupling pattern genetic underpinnings between height growth, drought based on δ13C...

In this study we applied approach 1,281 individuals with known pedigree long-term genetic test plantations lodgepole pine western Canada. We assessed resistance, resilience recovery metrics, analyzed their causal relationships susceptibility disease through structural equation modeling. found that trees low short-term events also...
Abstract Mechanistically predicting the evolutionary response of tree species to climate change requires an understanding genetic variation in relevant traits. Here we compared phenotypic and Leaf Economics Spectrum (LES) traits gas exchange vapour pressure deficit (VPD) lodgepole pine (Pico) white spruce (Pigl), early a late successional dominating boreal forests western Canada. We measured exchange, foliar nitrogen lamina mass area ratio 697 c . 30‐year‐old trees two field progeny trials....
