The effect of tissue N and P on growth of Porphyra yezoensis (strain U-51) blades in suspension cultures was investigated. Blades had the ability to store N in excess of requirements. The critical (0.40% fresh wt) and subsistence (0.153% fresh wt) levels of N were constant regardless of N source (NO−3 − or NH4 +) or light level. Blades did not have the ability to store excess P over the range of P loads given. The subsistence quota for P was higher when NH4 + was given, suggesting a decreased… CONTINUE READING
