Fine Root Density Dynamics and Carbon Stock of Eucalyptus spp.: Interplay of Age, Genotype, and Edaphoclimatic Conditions

Roots play a fundamental role in forest ecosystems, but obtaining samples from deep layers remains a challenging process due to the methodological and financial efforts required. In our quest to understand the dynamics of Eucalyptus roots, we raise three fundamental questions. First, we inquire abou...

In our quest to understand the dynamics of Eucalyptus roots, we raise three fundamental questions. First, we inquire about the average extent of the roots of two contrasting Eucalyptus genotypes. Next, we explore the factors that directly influence the growth and depth of these roots, addressing elements such as soil type, climate, and water availability. Lastly, we investigate how the variation in Eucalyptus species may impact root growth patterns, biomass, and carbon stock. In this study, we observed that the maximum root depth increased by an average of 20% when genotypes were grown on sites with higher water availability (wet site). E. urophylla stands had a higher biomass and carbon stock (5.7 Mg C ha−1) of fine roots when cultivated on dry sites (annual rainfall~727 mm) than the wet sites (annual rainfall~1590 mm). In E. grandis × E. camaldulensis stands, no significant differences were observed in the stock of fine root biomass (3.2 Mg C ha−1) between the studied environments. Our results demonstrated that genotypes with greater drought tolerance (E. grandis × E. camaldulensis) tend to maintain higher stocks of fine root biomass (3.2–6.3 Mg ha−1) compared to those classified as plastic (E. urophylla), regardless of the edaphoclimatic conditions of the cultivation site. Finally, our research helps understand how Eucalyptus trees adapt to their environment, aiding sustainable forest management and climate change mitigation. We also provide a practical tool to estimate underground biomass, assisting forest managers and policymakers in ensuring long-term forest sustainability.Department of Forestry Sciences Federal University of Lavras (UFLA)Department of Forestry Sciences São Paulo State University “Júlio Mesquita Filho” (UNESP)Institute of Forestry Research and Studies (IPEF)Warnell School of Forestry & Natural Resources University of GeorgiaSuzano SAKlabinDepartment of Forestry Sciences São Paulo State University “Júlio Mesquita Filho” (UNESP)Universidade Federal de Lavras (UFLA)Universidade Estadual Paulista (UNESP)Institute of Forestry Research and Studies (IPEF)University of GeorgiaSuzano SAKlabin2025-04-29T20:06:23Z2024-06-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://dx.doi.org/10.3390/plants13111503Plants, v. 13, n. 11, 2024.2223-7747https://hdl.handle.net/11449/30649910.3390/plants131115032-s2.0-85195936225Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengPlantsinfo:eu-repo/semantics/openAccessBasílio, Josiana Jussara Nazaré [UNESP]Campoe, Otávio Camargo [UNESP]Queiroz, Túlio Barroso [UNESP]de Souza, Cléber RodrigoCarneiro, Rafaela LorenzatoAlvares, Clayton Alcarde [UNESP]Figura, Marco Aurélio2025-04-30T13:55:16Zoai:repositorio.unesp.br:11449/306499Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestrepositoriounesp@unesp.bropendoar:29462025-04-30T13:55:16Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
