The selenium accumulation characteristics of grape seedlings

Abstract

To study the selenium accumulation characteristics of fruit tree, different selenium concentrations (0.00, 0.05, 0.10, 0.25, 0.50, 1.00, 2.00 mg/L) were used on the grape seedlings, and the selenium accumulation characteristics of grape seedlings were studied by a pot experiment. With the increase of selenium concentration in culture medium, the biomass of grape seedlings had increase trend when the culture medium selenium was no more than 0.05 mg/L, and decreased when the culture medium selenium was exceeded than 0.05 mg/L. When the culture medium selenium was 0.05 mg/L, the biomass of grape seedlings got the maximum. For selenium content in plants, with the increase of selenium concentration in culture medium, the selenium contents in roots and shoots of grape seedlings increased. Therefore, lower selenium concentration in culture medium could promote the growth of grape seedlings, while higher selenium concentration inhibited, and grape seedlings had strong selenium uptake ability.
