The aim of this work was to determine the effect of phosphorus in the relationship between total flavonoids concentration in leaves and fruits of Dimorphandra mollis Benth and the effect of different phosphorus levels, in nutrient solution, in the fresh and dry matter production by this specie. The experimental design was completely randomized with six replications and five treatments, with six plants per plot. The treatments were five levels of P in nutrient solution: 0.1, 0.5, 1.0, 2.0 and 4.0 mg L⁻¹ of P. After 90 days of cultive in nutrient solution, the plants were harvested and fresh and dry weights were evaluated and total flavonoids were quantified through spectrophotometric method using AICI₃ at 425 nm and rutin as standard. It was verified the increase of phosphorus levels and the biomass decrease. The highest total flavonoids concentration was verified with 0.1 mg/L of P.
