Resumo: The senescence and fall of the leaves and branches are mechanisms where thetrees can recycle the nutrients by biochemical cycling and by biogeochemical cycling. The objective of this paper was to evaluate the nutrients retranslocation in the non-deciduous leaves and branches and also in the deciduous leaves and branches. The leaves and branches for analysis were collected in the subplots of Acacia mearnsii stand at the age of three years old.The stand is located in the Rio Grande do Sul State – Brazil – in low fertility soil. The nutrients analysis results showed that the N was the element which had highest concentration for both, leaves and branches. The most retranslocated nutrients were P, K and Mg respectively. The elements N and Ca showed the lowest retranslocation in the leaves and branches.

Nesse sentido, o trabalho teve como objetivo avaliar,através da análise de folhas e galhos, a redistribuição de nutrientes entre as folhas e galhos não decíduos das árvores e as folhas e os galhos decíduos coletados nos coletores e subparcelas de um povoamento de Acacia mearnsii,com três anos de idade, plantado no Estado Rio Grande do Sul, Brasil, em solos de baixa fertilidade. Dentre os nutrientes analisados, o N de um modo geral, foi o que teve maior teor nas folhas e galhos. Em ordem crescente, o Mg, K e P foram os nutrientes que mais redistribuíram e o N e o Ca o que menos redistribuíram nas folhas e nos galhos.Embrapa Florestas2002-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1751Pesquisa Florestal Brasileira; n. 45 (2002): jul./dez.; 69-88Pesquisa Florestal Brasileira; No. 45 (2002): jul./dez.; 69-881983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1751/682Caldeira, Marcos Vinicius WincklerSchumacher, Mauro ValdirRodrigues, Loiva Mariainfo:eu-repo/semantics/openAccess2018-11-30T16:01:20Zoai:pfb.cnpf.embrapa.br/pfb:article/1751Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-11-30T16:01:20Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
