Details about some published studies on applied Se-based NPs biofortification.

Targeted plant (scientific name) Applied nano-dose Nutrient forms (preparing type) Growth media (applied method) Main findings References
Cucumber (Cucumis sativus L.) 25 mg L−1 Nano-Se (biological) Protected cultivation (foliar) Improved growth under heat and salinity stress Shalaby et al. (2021)
Bell pepper (Capsicum annuum L.), variety Kitrino Se-NPs at 10 and 50 mg L−1 Se-NPs (2–20 nm, chemical) Bags contained mixture peat and perlite in (1:1) Cu-NPs increased the content of bioactive compounds in fruits (flavonoids, carotene, yellow carotenoids) under saline stress González-García et al. (2021)
Chicory (Cichorium intybus L.) Nano-Se (4 and 40 mg l−1) Se-NPs (10–45 nm, chemical) Pots contained peat and perlite (1:1) Applied Se-NPs increased ascorbate concentration (31.5%) but reduced glutathione (35%) Abedi et al. (2021)
Paddy rice (Oryza sativa L.) 25–100 μmol L−1 Se NPs Nano-Se (chemical) Pot experiment (foliar) 50 μmol L−1 Se NPs is the best to ameliorate polluted soil (3.0, 300 mg kg−1 Cd and Pb Wang et al. (2021)
Bitter melon (Momordica charantia L.) From 1 to 50 mg L−1 Na2SeO4 and Se-NPs (10–45 nm, chemical) In vitro experiment Se treatments at low dose enhanced the activity of leaf nitrate reductase (52%) Rajaee Behbahani et al. (2020)
Strawberry (Fragaria×ananassa Duch.) Se/SiO2-NPs (50 and 100 mg L−1) Se-NPs (25 mg L−1, 60 nm, chemical) Pots filled with mixture of ratio (1:1:2) sand: animal manure: topsoil Applied Se/SiO2 at 100 mg L−1 can manage harmful impacts of soil drought stress via higher level of osmolytes like proline and carbohydrate Zahedi et al. (2020)
Tomato (S. lycopersicum L.), saladette “El Cid F1 From 10 to 20 mg L−1 Se-NPs (2–20 nm, chemical) Bags filled with peat moss and perlite (1:1) Se-NPs at 10 mg L−1 recorded the highest yield and improved quality of fruits Hernández-Hernández et al. (2019)
Tomato (S. lycopersicum L.), saladette El Cid F1 From 10 to 20 mg L−1 Se-NPs (2–20 nm, chemical) Bags filled with peat moss and perlite (1:1) Se-NPs at 20 mg L−1 promoted antioxidant system under biotic stress of fungal pathogen (Alternaria solani) Quiterio-Gutiérrez et al. (2019)
Groundnut (Arachis hypogaea L.) 20 and 40 mg l−1 Se-NPs (10–30 nm, chemical) Pot experiment (foliar) Improved yield components and oil production of seeds Hussein et al. (2019b)
Groundnut (Arachis hypogaea L.) 20 and 40 mg l−1 Se-NPs (10 – 30 nm, chemical) Pot experiment (foliar) Stimulator enhanced plant antioxidant defense system Hussein et al. (2019a)
Tomato (S. lycopersicum L.), saladette El Cid F1 From 5 to 20 mg L−1 Se-NPs (2–20 nm, chemical) Bags filled with peat moss and perlite (1:1) Se-NPs generated a positive impact against salinity stress and bioactive compounds in fruits for human health Morales-Espinoza et al. (2019)
Pomegranate: Punica granatum L. cv. Malase Saveh 5 L per tree at 1 or 2 μM Na2SeO4 and Se-NPs (10–45 nm, chemical) Field trial (foliar) NPs enhanced the maturity index; decreased cracking of fruits Zahedi et al. (2019b)
Strawberry (Fragaria ananassa Duch.), cv. Kurdistan 10 and 20 mg L−1 Se-NPs (10–45 nm, chemical) Pots filled with perlite, coco peat and sand (5:7:23) as foliar applied Se-NPs at 20 mg L−1 mitigated soil salinity stress and improved plant tolerance to salinity Zahedi et al. (2019a)
