Resumo: | Soils destined for forest crops are often limiting with respect to boron (B) and in several eucalyptus crops boron deficiency has been found to be a common occurrence. The objective of this study is to evaluate biomass production, B accumulation and Ca/B ratio in eucalyptus cultivated under different conditions of soil, water availability and doses of B. To that end, an experiment was conducted using a completely randomized design with a 5 x 2 x 2 factorial arrangement consisting of five doses of B (0.00, 0.25, 0.75, 2.25 and 6.25 mg kg-1), two types of soil, namely a Dark Red Latosol (LE) and a Red-Yellow Latosol (LV), and two water tension levels (-0.033 and -0.010 MPa), with four replicates. After plants were grown, determinations were made of Ca and B contents as well as Ca/B ratios in different portions of the plants. Accumulation of B was obtained from the ratio of its contents to dry biomass in each plant portion. It was found that, under natural conditions, both Dark Red Latosol and Red-Yellow Latosol fail to meet the nutritional requirements for B in eucalyptus, potentially being limiting to that species. Overall, soil moisture influenced dry biomass production and accumulation of B only in the case of the more sandy texture soil (Red-Yellow Latosol), denoting that this factor is conditional on soil texture. Ca/B ratio results showed that application of B to the soil without a suitable supply of Ca can lead to an imbalance between these nutrients, with possible implications for plant growth and nutrition. |

Os solos destinados aos plantios florestais são geralmente limitantes em boro (B) e, em vários plantios de eucalipto a deficiência desse elemento tem sido comum. Objetivou-se, no presente trabalho, avaliar a produção de biomassa, acúmulo de B e relação Ca/B em eucalipto cultivado em diferentes solos, disponibilidade de água e doses de B. Para tanto, foi conduzido um experimento utilizando o delineamento experimental inteiramente casualizado, em esquema fatorial 5 x 2 x 2, sendo cinco doses de B (0,00; 0,25; 0,75; 2,25 e 6,25 mg kg-1); dois tipos de solos: Latossolo Vermelho Escuro (LE) e Latossolo Vermelho Amarelo (LV) e duas tensões hídricas (-0,033 e -0,010 MPa), com quatro repetições. Após o cultivo das plantas, determinaram os teores de Ca e B, em seguida, as relações Ca/B nas diversas partes das plantas. O acúmulo de B foi obtido pela relação entre seus teores com a produção de biomassa seca das respectivas partes. Verificou-se que tanto o LE quanto o LV, nas suas condições naturais, não atendem às exigências nutricionais de B para o eucalipto, o que pode tornar limitante para a espécie. De maneira geral, a umidade do solo interferiu na produção de biomassa seca e no acúmulo de B somente no solo mais arenoso (LV), o que mostra um efeito dependente da textura do solo. A relação Ca/B mostrou que a aplicação de B ao solo sem o devido suprimento de Ca pode levar a um desequilíbrio entre esses nutrientes, com possíveis implicações no crescimento das plantas.CERNE2016-04-052017-08-01T20:15:20Z2017-08-01T20:15:20Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/903RAMOS, S.
