Resumo: | Abstract The bromeliads are desirable vase plants because of the flowering bract and the usually large, bold, colored and exotic format of the leaves that forms a cistern. The main function of epiphytic bromeliads roots is the fixation on the substrate, while water and nutrients uptake are performed mainly by leaves. However, recent studies have shown that the roots of epiphytic bromeliads can also help in the absorption of water and nutrients, contributing to plant growth and development. The present study aimed to evaluate the importance of the root system in the mineral nutrition of an epiphytic ornamental bromeliad silver vase bromeliad (Aechmea fasciata) that occurs in Brazil. 80 plants were cultivated for 240 days in plastic pots (900 mL) containing composted pine bark and were subjected to 5 treatments with 50 mL of 0% (control), 25%, 50%, 75% and 100% Hoagland & Arnon (HA) nutrient solution, applied twice a week only onto the substrate. Biometric and biomass variables of root and shoots, as well as macro- and micronutrients content in silver vase bromeliad leaves were evaluated. Results showed that all biometric and biomass parameters increased with the application of increasing HA solution concentrations, while the nutritional content in leaves showed different responses, with increase in nitrogen and potassium, decrease in calcium, phosphorus, magnesium, manganese, copper, sulfur, iron and zinc. We conclude that silver vase bromeliad grows better when fertilized with 75% or 100% HA solution on the substrate. We emphasize that the roots of the epiphytic silver vase bromeliad are functional and plays important roles in its nutrition and growth. |
