Rate of growth (mg, cm<sup>2</sup>) and O<sub>2</sub> output of the intertidal red alga <i>Porphyra umbilicalis</i> from Helgoland, North Sea, were measured during a 3 week culture in 3 different salinities (1/2-, 1- and 2-concentrated artificial sea water; Table 1). Under hypertonic conditions (2-concentrated sea water) growth rate and photosynthesis rate were depressed, compared to values obtained in normal concentrated sea water. Under hypotonic conditions (1/2-concentrated sea water), growth expressed in mg was the same as in normal concentrated sea water, or higher when expressed in cm<sup>3</sup>. Rate of O<sub>2</sub> output was almost unaltered in one of the two experiments, lowered in the other. Cell size increased at higher salinity, while swelling of cell walls and intercellular substances as well as the intensity of colouring decreased with salinity. The discrepancies between growth and photosynthesis under hypotonic conditions cannot be completely explained by the observed influences of salinity on morphological structures (cell size, swelling of cell substances). Detailed studies on the time course of photosynthesis and respiration rates, and preparation of a metabolic balance for the algae are necessary.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Some observations on the influence of salinity on growth and photosynthesis in <i>Porphyra umbilicalis</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-15 01:32:56.211754","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Cell wall; Respiration; Cell size ","OtherDescriptors":null,"Notes":null,"AnaPub":1971,"MonPub":null,"DateUpdate":"2018-09-11","DateCreate":"2018-09-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1971J996500010","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/bf02026768"},"refs":null,"anarec":{"AnaID":301042,"PubliDate":1971,"Pagination":"70-76","XtraPublOfAnaID":null,"ISBN":null,"Volume":"10","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
