Concentration and application method of selenium in pepper seedlings

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, there...

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. El selenio (Se) es considerado un elemento benéfico para las plantas; sin embargo, concentraciones elevadas pueden causar trastornos fisiológicos y morfológicos. El objetivo del estudio, fue identificar la concentración y método de aplicación de Se que permita la obtención de plántulas de calidad en cultivo de pimiento, por ello, se establecieron dos experimentos bajo condiciones de invernadero cultivados en solución nutritiva. En el experimento 1, para aplicación radical, se cultivaron plántulas en solución nutritiva enriquecida con Se en forma de Na3SeO4 en concentraciones de: 0.0, 1.0, 2.5, 5.0 y 10.0 μM. En el experimento 2, para aplicación foliar, las plántulas se asperjaron con Se en forma de Na3SeO4 en concentraciones de 0, 5, 10, 25 y 50 μM. En cada experimento se utilizó un diseño experimental completamente al azar con cinco repeticiones por tratamiento. El suministro de 1 y 5 μM de Se mediante aplicación radical y foliar respectivamente, estimularon el crecimiento de las plántulas de pimiento, asimismo, la presencia de Se en ambos métodos de aplicación, aumentó la concentración de pigmentos fotosintéticos en hojas. El Se mejoró la calidad de las plántulas, al inducir respuestas favorables en el crecimiento y concentración de pigmentos fotosintéticos.
