Abstract

The aim of this study was to investigate the physiological characteristics and quality of hypocotyls in the production of selenium-enriched sprouts from peanut seeds soaked in selenium (Se) solution. Peanut seeds were soaked with 0, 2.5, 5.0, 7.5, and 10 μmol/L Na2SeO3 for 12 h and then germinated. The results showed that the selenium concentration in peanut shoots increased with increasing levels of selenite soaking, and there existed a crossroads of selenite soaking concentration (5.0 μmol/L) when selenium concentrations in cotyledons and hypocotyls were equal. Below and above this concentration, Se concentrations in shoots were radicle > cotyledon > hypocotyl or cotyledon > radicle > hypocotyl, respectively. In addition, Se significantly promoted the elongation of hypocotyls and radicles, increased shoot biomass, increased the activity of antioxidant enzymes and the concentration of antioxidants in hypocotyls, and decreased malondialdehyde levels. Moreover, Se significantly increased the concentrations of soluble sugars, proteins, free amino acids and resveratrol in hypocotyls. These results indicate that soaking peanut seeds with selenite significantly increased Se concentration, biomass, antioxidant capacity and quality of peanut shoots. This study provides a theoretical basis for the rapid and standardised production of Se-enriched peanut shoots from selenite-soaked seeds.
