The effects of nitrogen fertilizer ( NF ) and phosphorus fertilizer ( PF ) on the growth as well as protein amino acid ( PAA ) and free amino acid ( FAA ) contents of Porphyra yezoensis in sea water were investigated. Single NF application did not improve P. yezoensis growth, but significantly increased its amino acid content. Single PF application significantly increased P. yezoensis growth, but decreased its amino acid content. Combined application of NF and PF could significantly promote the P. yezoensis growth, increase its amino acid content (including flavour amino acid) and thus improve its edible quality. Results indicate that combined application of NF and PF contributed to the growth and quality of P. yezoensis .
