Resumo: The objective of this work was to evaluate the effect of mineral nutrients on tree growth and wood quality of Pinus taeda, on commercial plantation at 20 years after planting, on different soil types. Experimental plots were set, and from trees representing each population, stem disks were collected at different heights. Treegrowth, wood quality and growth ring parameters – tracheids diameter and radial density by X-ray densitometry – were analyzed and related to mineral nutrient contents. Results showed negative correlation among Mn and Mg stem disk contents and Pinus taeda tree growth; negative correlation was also obtained among Ca, Mg and Mn contents and tracheids dimensions and wood density. There was no correlation among N, P, K and B contents in stem disks and tree growth or wood quality studied variables.  Dendronutrition concept – study of relationship among tree growth parameters and growth rings to mineral nutrient contents in stem – is discussed in this work.

Foram demarcadas parcelas experimentais e selecionadas árvores representativas da população para coleta de discos do lenho, a diferentes alturas do tronco. Parâmetros de crescimento das árvores e de qualidade da madeira e dos anéis de crescimento - dimensões dos traqueídeos e densidade radial por densitometria de raios X - foram analisados e relacionados com o teor de nutrientes minerais. Os resultados mostraram correlações negativas entre o teor de Mn e Mg no lenho com o crescimento das árvores e entre os teores de Ca, Mg e o Mn e as dimensões dos traqueídeos e densidade do lenho; não foi verificada correlação entre os teores de N, P, K e B no lenho com as variáveis analisadas. O conceito de dendronutrição - estudo da relação entre os parâmetros de crescimento das árvores e dos anéis de crescimento com os nutrientes minerais no lenho - é discutido no presente trabalho.Embrapa Florestas2010-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/132Pesquisa Florestal Brasileira; n. 54 (2007): jan./jun.
