Physalis angulata L. (Solanaceae), popularly known as ‘camapu’, has high pharmacological and agroindustrial potential. However, because it essentially is a wild species, studies on the physiological quality of its seeds are still scarce. In this sense, the objective was to evaluate the physiological performance of P. angulata seeds as a function of pre-germination treatments with chemical promoters. For this, germination, first germination count, germination speed index and seedling emergence tests were performed. The substrate was previously moistened with solutions of gibberellic acid – GA3 (0.00, 0.02, 0.04, 0.06 and 0.08%), potassium nitrate – KNO3 (0.0, 0.2, 0.4, 0.6, 0.8 and 1.0%) and Stimulate ® (0.00, 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50%). Each chemical promoter constituted an independent experiment, in a completely randomised design, with four replicates of 25 seeds each. The three chemical promoters enhanced the physiological performance of P. angulata seeds, and the concentrations of 0.05% GA3, 0.4% KNO3 and 1.0% Stimulate ® were most suitable.
