SEROLOGICAL STUDIES OF MALE AND FEMALE STRAINS OF EUDORINA ELEGANS (CHLOROPHYCEAE)1,2

Male and female strains of Eudorina elegans Ehrenberg were examined by serological methods for flagellar and cellular antigenic differences. No significant differences could be detected between the strains by using agglutination, immobilization and diffusion tests. However, differentiated sperm were neither agglutinated nor immobilized by anti-vegetative cell sera.
