Abstract: Abstract:The influence of NO3(superscript -),NO2(superscript -) and NH4(superscript +)(0.4 mM,1 mM,2 mM,4 mM and10mM)on the growth of the conchocelis of Porphyra haitanensis collectedfrom Kinmen was examined.After 30 days of cultivation in the modifiedSWM Ⅲ solution containing different concentrations of NO3(superscript -),NO2(superscript -)and NH4(superscript +)under the condition of 20℃,12:12 and 60 μE/m^(2)/s,the conchocelis showed anoptimum growth in the medium containing 1 mM NO3(superscript -).Under that conditionit increased 20.12 fold and 33.25 fold in term of dry weight and original volumerespectively.In general,NO3(superscript -)was the most favorable N-source for the growthof conchocelis and NH4(superscript +)the least.It was also found that the growth ofconchocelis decreased with increasing concentration of the N-salts.Theinfluence of different salinities(20,25,30,40,45 and 50‰)on the growth ofthe conchocelis was also tested.Under 20℃,60 μE/m^(2)/s,12:12 condition,theconchocelis grew well in the modified SWM Ⅲ medium at all salinities tested,with optimum at salinity 30‰,at which it increased 4.93 fold in term of dryweight,or 17.65 fold in term of volume.The lowest growth rate was observedin the medium with salinity of 50‰,at which it increased only 1.14 fold and8.40 fold in term of original dry weight and volume respectively.
