Other claims from this paper (15)
- Intervention effect Fe-peptide increased lettuce leaf iron concentration by up to 690% versus control.
- Intervention effect Zn-peptide increased lettuce leaf zinc concentration by 222% versus control.
- Observation Fertilizers induced cultivar-specific changes in primary and secondary metabolism.
- Intervention effect Aquino shoot fresh weight and root fresh and dry weight increased, especially with peptide and Zn-peptide.
- Observation Aquino leaf total amino acids, vitamin C, and soluble carbohydrates increased.
- Observation Barlack had a stronger antioxidant response, DPPH activity, and higher leaf flavonoids and anthocyanins.
- Intervention effect Peptide fertilizers reduced soluble carbohydrates and total anthocyanins in both cultivars.
- Intervention effect Peptide fertilizers reduced vitamin C in Aquino leaves.
- Intervention effect Peptide fertilizers reduced amino acids in Barlack leaves.
- Intervention effect Peptide treatment increased amino acids in Aquino leaves.
- Intervention effect Zinc peptide reduced Barlack shoot dry biomass.
- Intervention effect Zinc peptide reduced Barlack leaf total phenol and antioxidant activity.
- Intervention effect Zn-peptide and peptide treatments reduced leaf phosphorus in both cultivars.
- Intervention effect Zn-peptide and peptide treatments increased leaf boron concentration in both cultivars.
- Recommendation The authors support cultivar-specific peptide biochelates for targeted lettuce biofortification.
