Interactive Effects between Zinc and Selenium on Mineral Element Accumulation and Fruit Quality of Strawberry

In this study, we evaluated zinc (Zn) and selenium (Se) biofortification in strawberry fruits under substrate soil cultivation, along with their effects on mineral element accumulation fruit quality. To achieve this, foliar Zn (0.1% 0.2%) Se (0.003% 0.006%) fertilizers were applied separately or combination at the initial flowering stage. The contents increased spraying dosage. Compared to control, content first batch of Zn-treated strawberries by 36.9–109% 27.1–102% respectively, while 313–444% 21.3–53.3%, respectively. However, application could not ensure long-term sustainability as gradually decreased two subsequent batches, was more stable. three batches Se2 (0.006%)-treated grown 32.9%, 124%, 109%, Meanwhile, compared alone, Zn–Se combined 61.2–77.6% 24.9–45.7% low doses promoted enrichment (by 8.62–40.9%) high inhibited it 13.2–28.9%) cultivation. Moreover, copper cultivation after Se1 (0.003%) treatment significantly higher 75.0%) than that control. A positive correlation observed between Cu both consistent impact also (0.006%) caused an increase ascorbic acid 37.2%) fruits. soluble sugar 36.3% Zn1 (0.1%) treatment. present study provides a practical basis for Se.
