Abstract
Male and female gametophytes of Desmarestia aculeata have been grown as clonal cultures. Red light permits vegetative growth only. Differentiation of oogonia and antheridia takes place under illumination with blue light as has been previously reported for several species of Laminaria. Morphological details for differentiation of oogonia and antheridia are presented, stressing the strong resemblance with the respective processes in Laminaria. Experimental evidence indicates the presence of a hormonal factor secreted by the eggs, which is responsible for discharge and subsequent attraction of spermatozoids to the egg.Keywords
