Cerium improves plant growth and fruit quality of strawberry plants under salt stress by changing the antioxidant capacity and water physiology

This study investigated the effects of cerium (Ce) on growth and fruit quality strawberries under salt stress. The findings revealed that stress markedly enhanced activities antioxidant enzymes increased contents malonaldehyde (MDA) hydrogen peroxide (H2O2) in leaves anthocyanins, phenolic compounds, vitamin C (Vc), soluble sugar (SS) titratable acid (TA) fruits. Ce improved ascorbate peroxidase, superoxide dismutase, peroxidase catalase Vc SS fruits, but significantly decreased MDA H2O2 levels TA content fruits However, chlorophyll (Chl) carotenoids (Car), photosynthetic rate (Pn), transpiration (Tr), stomatal conductance (gs), relative water (RWC), plant height biomass, weight sugar-acid ratio (SAR). Compared with alone, obviously Chl Car contents, Pn, Tr, gs, RWC, as well SAR. above results suggested showed beneficial
