摘要

The growth of an individual thallus of the brown alga Laminaria japonica was studied in a laboratory environment. It was found that daily accretion of the Laminaria thallus can remain constant for a long time. The blade grew in length at a distance from 0 to 15-25 cm from the stipe-blade border, which makes up 60% of the blade length. In width, the blade grew both in the central and in the lateral parts of the blade, 0 to 7-10 cm from the stipe-blade border, which makes up 30% of the frond length. The transposition of a perforation hole mark from the stipe-blade border toward the blade tip evidenced the formation of new tissue in the growth zone even when the thallus diminished in size due to destruction of the blade tip. Based on the results of this observation, it was concluded that both restraint of accumulation and even reduction of the algal thallus in biomass and size cannot be taken as an indication of algal growth cessation.
