Effect of dissolved calcium on the formation of secondary attachment structures in different types of branches of Chondracanthus chamissoi (Rhodophyta, Gigartinales)

Development of secondary attachment structures (SAS) was evaluated in apical fragments of pinnules, and basal and lateral branches in the carrageenophyte Chondracanthus chamissoi. When no dissolved calcium was added to the culture medium, most basal and lateral branches initiated SAS formation, whil...
