Abstract –      We carried out greenhouse experiment to evaluate the effect of silicon (Si) on growth and mineral nutrition of yellow passion fruit (Passiflora edulis) submitted to saline stress in a nutritive solution. The experiment comprised a completely randomized design in a 5x4 factorial scheme: five NaCl concentrations (0; 7.5; 15; 30 and 60 mmol L-1) and four SiO2  concentrations (0; 0.5; 1.0 and 1.5 mmol L-1) with four replicates. At the end of 35 days, we measured stem diameter, leaves, stem, and roots dry matter, as well as the macronutrient, Na, Cl, and Si leaf accumulation in plants. In most cases, the increase in NaCl supply in a nutritive solution reduced the dry matter of roots, stem, and leaves. The SiO2  supply attenuated the effect on higher tested saline stress (30 and 60 mmol L-1 NaCl) on roots and stem dry matter. The application of 0.5 mmol L-1 of SiO2 reduced the deleterious effect of salinity on all macronutrients absorption in yellow passion fruit cultivated in a nutritive solution.

Resumo -       Realizou-se um experimento em casa de vegetação para avaliar o efeito do silício (Si) no crescimento e na nutrição mineral do maracujazeiro-amarelo (Passiflora edulis) submetido ao estresse salino em solução nutritiva. Utilizou-se o delineamento inteiramente casualizado em esquema fatorial 5x4: cinco concentrações de NaCl (0; 7,5; 15; 30 e 60 mmol L-1) e quatro concentrações de SiO2  (0; 0,5; 1,0 e 1,5 mmol L-1) com quatro repetições. Ao final de 35 dias, mensuraram-se o diâmetro do caule, a matéria seca das folhas, caule e raízes, além dos teores de macronutrientes, Na, Cl e Si nas folhas das plantas. Na maioria dos casos, o aumento no fornecimento de NaCl em solução nutritiva reduziu a produção de matéria seca das raízes, do caule e das folhas das plantas. O suprimento de SiO2  atenuou o efeito do maior estresse salino (30 e 60 mmol L-1 NaCl) na matéria seca das raízes e do caule. A aplicação de 0,5 mmol L-1 de SiO2  reduziu o efeito deletério da salinidade na absorção de todos os macronutrientes pelo maracujazeiro-amarelo cultivado em solução nutritiva.
