ABSTRACT

The regularity of formation of morphological structure of Laurencia papillosa (Forsk.) Grev. (Rhodophyta) thallus in bath culture for different temperature (15 and 20 °С) and light intensity (31 and 40 W/m2 PАR) were studied. Under transfer of Laurencia from the natural environment into culture the morphological organization follows extensive strategy (increase of the biomass through increasing the diameter and length of axis of thallus) that is most usual in the natural environment. Then the strategy changes for intensive through formation of new growth zones in secondary to quaternary branches but never in primary branches. Increase of the secondary branches for 30 day cultivation was about 180 and increase of the tertiary branches was more 100. As the result, the specific surface increases. In altering one strategy for the other temperature plays an important role and the intensity of light is the essential factor.
