Dictyota dichotoma. Temporal variation of vegetative and reproduction parameters. 20 Seasonal variation of length, width and height of medullar cells and daylength. Significant differences between seasons (α < 0.05) are indicated by different letters (SNK-tests). 21 Monthly variation of diploid, haploid and vegetative thalli. 22 Seasonal variation of diploid, haploid and vegetative thalli. 23 Monthly variation of female and male gametangia/10 mm2 of examined algal tissue, male/female ratio and daylength. 24 Monthly variation of female and male gametangia formed per mm2 of examined algal tissue and daylength. 25 Seasonal variation of female and male gametangia/mm2 of examined algal tissue and total apical and basal gametangia/mm2 examined algal tissue. Significant differences between seasons (α < 0.05) are indicated by different letters (SNK-tests)
