Effects of salinity on growth, photosynthesis and respiration in a freshwater alga Rhizoclonium riparium (Chlorophyceae, Cladophorales)
SUMMARY A freshwater green alga, Rhizoclonium riparium (Roth) Harvey, was found to grow in diluted seawater with salinities (PSU) from 0.1 to 34.0 (0.1–34.0 S). It grew best at 13.6 S and least at 0.1 S which was the least salinity reported in its habitat. Net photosynthetic oxygen production of R....

| description | SUMMARY
A freshwater green alga, Rhizoclonium riparium (Roth) Harvey, was found to grow in diluted seawater with salinities (PSU) from 0.1 to 34.0 (0.1–34.0 S). It grew best at 13.6 S and least at 0.1 S which was the least salinity reported in its habitat. Net photosynthetic oxygen production of R. riparium rose with salinity up to 34.0. However, in the medium adjusted at pH 8.1. the net photosynthesis rose at low ranges of salinity and was almost at the same level in all ranges of salinities examined. The net photosynthesis was increased by the addition of bicarbonate in the medium. Respiratory oxygen consumption did not rise with the increase of external salinities from 0.1 to 34.0. The results indicate that R. riparium can grow by increasing net photosynthesis in diluted seawater in which the pH value is suitable for effective bicarbonate supply to photosynthesis. |
