    Abstract. Seedlings of Laminaria groenlandica Rosenvinge. L. saccharina (L.) Lamour. and Cymathere triplicata (Post. & Rupr.) J. Ag. were produced directly from mixed gametophytes and indirectly from cloned gametophytes. When cultivated in the sea, these seedlings produced up to 8 wet kg.m−1 of cultivation rope for L. saccharina, 20 wet kg.m−1 for L. groenlandica and 2·7 wet kg.m−1 for C. triplicata. These values are similar to those reported from other parts of the world. Plant sizes for cultivated L. groenlandica and C. triplicata were greater than observed in wild stands Production by L. groenlandica was positively correlated with nutrient concentrations and negatively correlated with temperature. The time required to achieve harvestable size may he reduced from 16 to 9 months by employing seedlings produced indirectly from cloned gametophytes.

    Abstract Nitrate and ammonium uptake rates were measured for three year-classes of the perennial macrophyte Laminaria groenlandica Rosenvinge, collected from nitrogen-depleted waters in Barkley Sound, British Columbia, Canada, in summer 1981. A time course of uptake rate revealed that ammonium uptake was high during the first hour and then decreased for all three year-classes; the opposite pattern was exhibited for the time course of nitrate uptake rate. Nitrate uptake rate increased linearly with nitrate concentration up to the highest level tested (60 μM). The nitrate uptake rate of first-year plants was three times higher than second- and third-year plants; ammonium uptake rates showed similar patterns to those for nitrate. The interaction between nitrate and ammonium was examined for first-year plants. Nitrate and ammonium were taken up simultaneously and uptake rates were identical and equal to uptake rates when only nitrate or ammonium was present in the medium. Therefore, first-year plants are able to take up twice as much inorganic nitrogen per unit time when both nitrate and ammonium are present. First-year plants showed significant diel periodicity in ammonium uptake rates, whereas second- and third-year plants showed no periodicity in nitrate or ammonium uptake rates.
