Figs. 14–19

Dictyota dichotoma. Temporal variation of vegetative parameters (mean ± SD). 14 Variation of frond length, daylength and surface water temperature monitored during April 2009 and March 2010. 15 Seasonal variation of frond length, frond dry mass and daylength. 16 Seasonal variations of length and width interdichotomies and daylength. 17 Seasonal variation of primary branches occurrence, main axes and daylength. 18 Seasonal variation of apical and basal branching and daylength. 19 Seasonal variation of length, width and height of cortical cells and daylength. In Figs. 15, 16, 17, 18 and 19, significant differences between seasons (α < 0.05) are indicated by different letters (SNK-tests)
