Juveniles generados a partir de esporas no asentadas de Chondracanthus chamissoi (Rhodophyta, Gigartinales) presentan capacidad de adhesión al sustrato

Spores of some Gigartinaceae can germinate while drifting, and develop into unattached, multicellular, spherical juveniles (JNA). In the lab, growth of JNA of Chondracanthus chamissoi was positively affected by light intensity. Also, when 4-month old JNA were placed on artificial substrata, over 60%...
