Abstract
Investigations were conducted on the germination of tetraspores of the intertidal seaweed
Stoechospermummarginatum (C. Ag.) Kutz. The influence of light on the polarity of the spores
was also studied, and preliminarystudies were carried out on the response of the germlings to
different salinities. A wide range in tetraspore size was observed. After the first cell division one
cell developed into a rhizoid, and the other into a mass of cells, the central nodule, from which a
primary shoot with a single apical cell arose. This shoot developed into a broad and flat structure,
which subsequently branched dichotomously. Secondary shoots were formed in two ways: from
the central nodule and from the primary rhizoid. The spores showed light induced polarity. Very
high and very low salinities were not tolerated.
