Resumo: | http://dx.doi.org/10.5902/1980509812350This study had as objective to evaluate nutrients content and allocation pattern in different biomasscomponents of Platanus x acerifolia, in a 5.5 year stand, located in Dom Feliciano, Rio Grande do Sul state.Twenty-four trees were sampled, based on diametric amplitude, with biomass determination in the followingcomponents: leaves, fruits, stem bark, wood and roots. To study the variation of nutrients concentration,wood and bark samples were collected in different positions along the stem. Nutrients stock estimation, ineach component, was based on biomass average values and nutrients content, by the number of trees perdiametric classes per hectare. Nutrients content variation along the stem, in bark and in wood was studiedbased on regression equations adjustment, correlating nutrients concentration and the point of collection.Considering all biomass components, the following sequence according to nutrients concentration was: N> Ca > K > Mg > P > S > Fe > Mn > B > Zn > Cu. The highest contents, for most nutrients, were observedin leaves and the lowest, for all nutrients, were observed in the wood. Total nutrients stock in Platanus xacerifolia biomass was 574.72 kg ha-1, according to the following allocation order, among the components:wood ~ branches > roots ~ leaves > bark > fruits. Regarding to nutrients, the accumulation sequence was feasfollows: N > K > Ca > Mg > S > P > Fe > Mn > B > Zn > Cu, where N, K and Ca represent 82.9% fromthe total. It was verified a great variance in nutrient concentration along the stem, bark and wood, withdistinction of basic patterns: growing, decreasing and invariable, from the base of the tree towards to thetop. |

Foram amostradas 24 árvores, com base na amplitude diamétrica, com determinação da biomassa, concentração e estoque de nutrientes nos seguintes componentes: folhas, frutos, galhos, casca do tronco, madeira do tronco e raízes. Para estudar a variação no teor dos nutrientes foram coletadas amostras de casca e madeira em diferentes posições ao longo do tronco. A estimativa do estoque de nutrientes, em cada componente, baseou-se nos valores médios, da biomassa e do teor de nutrientes, pelo número de árvores por classe diamétrica por hectare. A variação da concentração dos nutrientes ao longo do tronco, na casca e na madeira, foi estudada a partir do ajuste de equações de regressão, correlacionando concentração de nutrientes e a altura de coleta das amostras. Em termos médios, considerando-se todos os componentes da biomassa, prevaleceu a seguinte sequência quanto à concentração nutricional: N > Ca > K > Mg > P > S > Fe > Mn > B > Zn > Cu. Os maiores teores, para a maioria dos nutrientes, foram observados nas folhas e os menores, para todos os nutrientes, foram verificados na madeira do tronco. O estoque total de nutrientes na biomassa de Platanus x acerifolia foi de 574,72 kg ha-1, de acordo com a seguinte ordem de alocação, entre os componentes: madeira do tronco ~ galhos > raízes ~ folhas > casca do tronco > frutos. Quanto aos nutrientes, a sequência de acúmulo foi a seguinte: N > K > Ca > Mg > S > P > Fe > Mn > B > Zn > Cu, sendo que N, K e Ca, representam 82,9% do total. Foi verificada grande variação na concentração de nutrientes ao longo do tronco, na casca e na madeira, com distinção dos padrões básicos: crescente, decrescente e invariável, da base da árvore em direção do ápice.
