Abstract To study the effect of exogenous selenium on fruit quality in walnut (Juglans regia L.), 8-year-old walnut
(Qingxiang) was taken as the research object. In the fruit expansion stage, 300 mg/L of sodium selenate, yeast
selenium and sodium selenite solutions were applied on the leaf of walnut, and the selenium levels in leaves,
pericarp and kernel were determined at the ripening stage. The fruit quality, mineral nutrient content, antioxidant
enzyme activity, and related genes’ expression were analyzed. The results showed that the three exogenous
selenium increased the selenium levels in leaves, pericarp and kernel of walnut. They also significantly increased… More >
