Sumario:Selenium (Se) is considered a beneficial element for plants; however, high concentrations can cause physiological and morphological disorders. The objective of the study was to identify the concentration and application method of Se that allow obtaining quality seedlings in pepper cultivation, therefore, two experiments were established under greenhouse conditions cultivated in nutrient solution. In experiment 1, for root application, seedlings were grown in a nutrient solution enriched with Se in the form of Na3SeO4 at concentrations of: 0.0, 1.0, 2.5, 5.0 and 10.0 μM. In experiment 2, for foliar application, the seedlings were sprayed with Se in the form of Na3SeO4 at concentrations of 0, 5, 10, 25 and 50 μM. In each experiment, a completely randomized experimental design with five replications per treatment was used. The supply of 1 and 5 μM of Se through root and foliar application, respectively, stimulated the growth of pepper seedlings, similarly, the presence of Se in both application methods increased the concentration of photosynthetic pigments in leaves. Se improved seedling quality by inducing favorable responses in growth and concentration of photosynthetic pigments.
