Productivity of two morphological forms of Laurencia papillosa (Forsk.) Grev. (Rhodophyta) in culture
Краткое описание
Productive properties of the Black Sea agar-containing alga Laurencia papillosa (Forsk.) Grev. (Rhodophyta) have been investigated in enrichment culture for 30 days. It was shown that under a temperature of 15 °C and light intensity of 40 W/m2 PAR alga had a higher specific growth rate. Values of specific growth rate and maximal specific growth rate were 0.085 and 0.165 day−1, respectively. Two morphological forms of laurencia were tested concerning their reaction on the changes of light intensity and temperature to find a correlation between morphostructure of the thallus and its productive characteristics under different conditions of cultivation. The experiment demonstrated that the morphostructure of thalli in the population may determine productive properties of laurencia under nearly optimal conditions.
